Catheter ablation is a procedure that uses radio-frequency energy or other sources to terminate or modify a faulty electrical pathway from sections of the heart of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter and Wolff-Parkinson-White syndrome.
Ablation near the electrode in a flashtube.The high-energy electrical arc slowly erodes the glass, leaving a frosted appearance. Ablation (Latin: ablatio – removal) is the removal or destruction of something from an object by vaporization, chipping, erosive processes, or by other means.
In the process, chlorine gas is decomposed into free radical chlorine which is then reacted with PVC in a post-production step, essentially replacing a portion of the hydrogen in the PVC with chlorine. Depending on the method, a varying amount of chlorine is introduced into the polymer allowing for a measured way to fine-tune the final properties.
It is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride (PVC). Vinyl chloride is a colourless flammable gas that has a sweet odor and is carcinogenic . Vinyl chloride monomer is among the top twenty largest petrochemicals ( petroleum -derived chemicals) in world production. [ 2 ]

A premature ventricular contraction (PVC) is a common event where the heartbeat is initiated by Purkinje fibers in the ventricles rather than by the sinoatrial node. PVCs may cause no symptoms or may be perceived as a "skipped beat" or felt as palpitations in the chest.
To change this template's initial visibility, the |state= parameter may be used: {{Strength training exercises | state = collapsed}} will show the template collapsed, i.e. hidden apart from its title bar. {{Strength training exercises | state = expanded}} will show the template expanded, i.e. fully visible.
