Liquefied natural gas, or LNG, is natural gas in its liquid form. LNG is produced by purifying natural gas and super-cooling it to -260Â°F to turn it into a liquid. During the process known as liquefaction, natural gas is cooled below its boiling point, removing most of the extraneous compounds found in the fuel.
Ventricular tachycardia (V-tach, often abbreviated VT) refers to a rhythm that arises from the ventricles causing the heart to beat at a rate faster than 100 beats per minute. The ventricular rate is usually above 120 beats/min and may exceed 250 beats/min.
During EPS, sinus rhythm as well as supraventricular and ventricular arrhythmias of baseline cardiac intervals is recorded. The study is indicated to investigate the cause, location of origin, and best treatment for various abnormal heart rhythms. This type of study is performed by an electrophysiologist and using a single or multiple catheters situated within the heart through a vein or artery.
