pos: Premature ventricular contraction Premature ventricular contraction A premature ventricular contraction (PVC)—also known as a premature ventricular complex, ventricular premature contraction (or complex or complexes) (VPC), ventricular premature beat (VPB), or ventricular extrasystole (VES)—is a relatively common event where the heartbeat is initiated by Purkinje fibers in the ventricles rather than by the sinoatrial node, the normal heartbeat initiator. PVCs may cause no symptoms at all, but they may also be perceived as a "skipped beat" or felt as palpitations in the chest. Single beat PVC abnormal heart rhythms do not usually pose a danger. The electrical events of the heart detected by the

pos: Concealed conduction Concealed conduction Concealed conduction is tissue stimulation without direct effect, but leading to a change in conduction characteristics. A common example would be an "interpolated PVC" (a type of premature ventricular contraction) during normal sinus rhythm; the PVC does not cause an atrial contraction, because the retrograde impulse from the PVC does not completely penetrate the AV node. However, this AV node stimulation can cause a delay in subsequent AV conduction by modifying the AV node's subsequent conduction characteristics. Hence, the P-R interval after the PVC is longer than the baseline P-R interval. Another variation on this concept is seen

pos: Concealed conduction in atrial flutter. As a result of the rapid atrial rate, some of the atrial activity fails to get through the AV node in an antegrade direction but can alter the rate at which a subsequent atrial impulse is conducted. In this circumstance, an alteration in the F-wave to QRS relationship is seen.

neg: Polyvinyl chloride In Europe the consumption of PVC for medical devices is approximately 85,000 tons each year. Almost one third of plastic-based medical devices are made from PVC. The reasons for using flexible PVC in these applications for over 50 years are numerous and based on cost effectiveness linked to transparency, light weight, softness, tear strength, kink resistance, suitability for sterilization and biocompatibility. Flexible PVC flooring is inexpensive and used in a variety of buildings, including homes, hospitals, offices, and schools. Complex and 3D designs are possible, which are then protected by a clear wear layer. A middle vinyl foam layer also

Reviewing Series 1, Episode 1 for "Radio Times", Tristram Fane Saunders found the show suited Amos "down to the ground; there's a touch of "Seinfeld" about "What Does the K Stand for?" in the way it flows from stand up into a deliciously awkward

neg: PVC clothing PVC clothing PVC clothing, commonly known as "vinyl clothing", is shiny clothing made of the plastic polyvinyl chloride (PVC). The PVC plastic is also called vinyl. For this reason, this type of clothing is also called vinyl clothing. PVC is sometimes confused with the similarly shiny patent leather. The terms "PVC", "vinyl" and "PU" tend to be used interchangeably by retailers for clothing made from shiny plastic-coated fabrics. These fabrics usually consist of a backing woven from polyester fibers with a surface coating of shiny plastic. The plastic layer itself is typically a blend of PVC and polyurethane (PU), with

Different coloured PVC garments, especially white, should be stored separately from each other, otherwise staining may occur. PVC clothing is best stored hanging in a garment bag away from other clothing. The fabric used for PVC clothes is typically plastic-coated polyester. This PVC fabric is more resistant to wear and tear than rubber, and PVC clothing does not require the use of any shining products. However one can polish PVC clothing if desired with liquid silicone spray which is available from car accessory shops.

Another important medical advancement for UHMWPE in the past decade has been the increase in use of fibers for sutures. Medical-grade fibers for surgical applications are produced by DSM under the "Dyneema Purity" trade name. UHMWPE is used in the manufacture of PVC (vinyl) windows and doors, as it can endure the heat required to soften the PVC-based materials and is used as a form/chamber filler for the various PVC shape profiles in order for those materials to be 'bent' or shaped around a template. UHMWPE is also used in

These fabrics usually consist of a backing woven from polyester fibers with a surface coating of shiny plastic. The plastic layer itself is typically a blend of PVC and polyurethane (PU), with 100% PVC producing a stiff fabric with a glossy shine and 100% PU producing a stretchy fabric with a silky shine. A manufacturer's label may say, for example, 67% polyester, 33% polyurethane for a fabric that contains no PVC; or 80% polyvinyl chloride, 20% polyurethane with

Heavier fetishists often attempt duplicating all kinds of "everyday wear" into a rubber counterpart. Some PVC enthusiasts are turned on by PVC Hazmat suits and other forms of industrial protective clothing. For hygienic reasons, many sex toys such as dildos and butt plugs are made from rubber or similar materials, and this is also a factor in rubber fetishism. Some rubber fetishists are also medical fetishists or have an interest in klismaphilia; medical gloves and catheters are

During production, it emits toxic byproducts including dioxin which has been linked to many cancers, neurological damage, respiratory problems, and birth defects among others. In addition to the health risks associated with PVC production, environmentalists associated with the film suggest that dioxins released through PVC plants do not disappear but are absorbed by animals and humans. PVC is also non-recyclable and highly flammable causing complications with the life cycle

The most basic material for the forming web is polyvinyl chloride (PVC). The principal advantages of PVC are the low cost and the ease of thermoforming. The main disadvantages are the poor barrier against moisture ingress and oxygen ingress. In the case of blister packaging the PVC sheet does not contain any plasticizer and is sometimes referred to as Rigid PVC or RPVC. In the absence

However, DEHP is coming under increasing pressure in Europe. The assessment of potential risks related to phthalates, and in particular the use of DEHP in PVC medical devices, was subject to scientific and policy review by the European Union authorities, and on 21 March 2010, a specific labeling requirement was introduced across the EU for all devices containing phthalates that are classified as CMR

The California Office of Environmental Health Hazard Assessment, charged with maintaining the Proposition 65 list and enforcing its provisions, has implemented a "No Significant Risk Level" of 146 ug/day for DINP, as of 1 April 2016. Phthalates are used in some but not all PVC formulations, and there are no specific labeling requirements for phthalates. PVC plastics are typically used for various containers and hard packaging, medical tubing, and bags, and are labelled "Type 3" for recycling reasons. However, the presence of phthalates rather than other plasticizers is not marked on PVC items. Only

The University of Illinois Medical Center in Chicago states that people who use products containing PVC can become exposed with harmful toxic phthalates and lead, which eventually can become a big contributor with dioxins. Lois Gibbs, executive director of the Center for Health, Environment, and Justice, stated, "Target is doing the right thing by moving away from PVC and switching to safer alternatives." Other companies reducing the PVC on their shelves include Walmart, Microsoft, Johnson & Johnson, Nike, and Apple. Target stores have

In 1998, the U.S. Consumer Product Safety Commission (CPSC) arrived at a voluntary agreement with manufacturers to remove phthalates from PVC rattles, teethers, baby bottle nipples and pacifiers. Plasticized PVC is a common material for medical gloves. Due to vinyl gloves having less flexibility and elasticity, several guidelines recommend either latex or nitrile gloves for clinical care and procedures that require manual dexterity and/or that involve patient contact for more than a brief period. Vinyl gloves show poor resistance to many chemicals, including glutaraldehyde-based products and alcohols

However, Diamond started branding both female and male PVC statues under the Gallery label. Similarly, Diamond's PVC statues of Marvel characters (both comics- and MCU-based) are branded under the Gallery label. Diamond makes resin busts for some of their licenses. Recent ones include Spider-Man based on his appearance in "Spider-Man: Homecoming" and characters from "Batman: The Animated Series". Diamond also makes mid-range resin statues.

The production of the PVC used in the production of many artificial leathers are a plasticizer called a phthalate to make it flexible and soft. PVC requires petroleum and large amounts of energy thus making it reliant on fossil fuels. During the production process carcinogenic byproducts, dioxins, are produced which are toxic to humans and animals. Dioxins remain in the environment long after PVC is manufactured. When PVC ends up in a landfill it does

However, like PVC, polyurethane does not last as long as leather, uses toxic solvents in the production process, and cannot decompose. Artificial leathers are often used in clothing fabrics, furniture upholstery, and automotive uses. One disadvantage of plastic-coated artificial leather is that it is not porous and does not allow air to pass through; thus, sweat can accumulate if it is used for clothing, car seat coverings, etc. One of its primary advantages, especially in cars,

A question that follows from this is whether it is ever actually possible for there to be nothing at all, or whether there must always be something. Grammatically, ""something" and "anything" are commonly classified as pronouns, although they do not stand for another noun so clearly as does "thing" itself, a word always classified as a noun". In predicate logic, what is described in layman's terms as "something" can more specifically be regarded as existential quantification, that is,

neg: Bigeminy a pause that can lead to the development of bigeminy. A PVC wavefront often encounters a refractory AV node that does not conduct the wavefront retrograde. Thus the atrium is not depolarized and the sinus node is not reset. Since the sinus p wave to PVC interval is less than the normal P-P interval, the interval between the PVC and the next p wave is prolonged to equal the normal time elapsed during two P-P intervals. This is called a "compensatory" pause. The pause after the PVC leads to a longer recovery time which is associated with a higher likelihood

The different international healthcare accreditation schemes vary in quality, size, cost, intent and the skill and intensity of their marketing. They also vary in terms of cost to hospitals and healthcare institutions making use of them. Increasingly, some hospitals are looking towards dual international accreditation, perhaps having both JCI to cover potential US clientele, and Accreditation Canada or QHA Trent. As a result of competition between clinics for American medical tourists, there have been initiatives to rank hospitals based on patient-reported metrics. Medical tourism carries some risks that locally provided medical care either does not

At a meeting of the ruling bodies of the PAIGC that month, Manuel Saturnino da Costa was appointed to replace Vieira as party leader. At a tripartite meeting conducted in late May by representatives of the government, the military junta and the political parties, agreement was reached that Vieira should stand trial for his involvement in arms trafficking to the Casamance separatists and for political and economic crimes relating to his terms in office. Vieira subsequently agreed to stand trial, but only after receiving medical treatment abroad, after which he pledged to return

The altered language and words used show a marked change in emphasis from talking in terms of disease or impairment to talking in terms of levels of health and functioning. It takes into account the social aspects of disability and does not see disability only as a 'medical' or 'biological' dysfunction. That change is consistent with widespread acceptance of the social model of disability. The medical model of disability focuses on the individual's limitations and ways to reduce those impairments or using adaptive technology to adapt them to society. Current definitions of disability accept biomedical assistance but focus

This is breach in its starkest, most commonsensical form: essentially a failure to comply with the terms of a contract. All terms are susceptible to breach; in other words, both positive and negative obligations can be breached. There are two requirements for ordinary breach in the case of a positive obligation: Where the debtor has a negative obligation, positive malperformance occurs when the debtor does the act he is bound to refrain from doing.

Flexner recommended that the proprietary medical schools should either close or be incorporated into existing universities. Medical schools should be part of a larger university, because a proper stand-alone medical school would have to charge too much in order to break even financially. Less known is Flexner's recommendation that medical schools appoint full-time clinical professors. Holders of these appointments would become "true university teachers, barred from all but charity practice, in the interest of teaching." Flexner pursued this objective for years,

But he does not invert this to find the "S" corresponding to a given "c" criterion (i.e. he does not solve for the hyperfocal distance), nor does he consider focusing at any other distance than infinity. He finally observes "long-focus lenses have usually a larger aperture than short ones,

Reductionism should be distinguished from eliminationism: reductionists do not deny the existence of phenomena, but explain them in terms of another reality; eliminationists deny the existence of the phenomena themselves. For example, eliminationists deny the existence of life by their explanation in terms of physical and chemical processes. Reductionism also does not preclude the existence of what might be termed emergent phenomena, but it does imply the ability to understand those phenomena completely in terms of the processes from which they are composed. This reductionist understanding is very different from emergentism, which intends that

UCC § 2-207(2) of the statute tells what to do with "additional" terms. It does not explicitly address what to do with "different" terms. A minority of states, led by California, infer that this was a typographical error by the drafters. As such, those states treat different terms in the same manner as additional terms. The majority rule, however, is that different terms do not become part of the contract; rather, both of the conflicting terms—from both

Those in favor of government policies for publicly funded medical research posit that removing profit as a motive will increase the rate of medical innovation. Those opposed argue that it will do the opposite, because removing the incentive of profit removes incentives to innovate and inhibits new technologies from being developed and utilized. The existence of sound medical research does not necessarily lead to evidence-based policymaking. For example, in South Africa, whose population sets the record for HIV infections, previous government policy limiting funding and access for AIDS treatments met with strong controversy given

After the war, PVC was not a popular choice of materials in the marine industry due to its density. In the 1970s, the need for a strong, moisture-resistant material led to plastic manufactures working with PVC to make it lighter. This led to the creation of PVC foamboard, by combining PVC with polyurea at the molecular level. PVC foamboard is made up of an interpenetrating polymer network between PVC and polyurea. Now, the manufacturing process has become much more involved. First,
