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.
A ventricular premature beat is an extra heartbeat caused by an abnormal electrical impulse starting in the lower chambers of the heart (the ventricles) before a normal heartbeat would occur. It is also known as a ventricular ectopic beat or a premature ventricular contraction.This is a form of arrhythmia that is similar to an atrial ectopic heartbeat. But where that affects the upper chambers of the heart (the atria), this affects the ventricles (or lower chambers of the heart). ventricular premature beat is an extra heartbeat caused by an abnormal electrical impulse starting in the lower chambers of the heart (the ventricles) before a normal heartbeat would occur. It is also known as a ventricular ectopic beat or a premature ventricular contraction.
