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.
This page provides an introduction to junctional rhythms and links to training materials on this website. The SA node is the normal origin of the electrical impulse for a heart beat. When the SA node cannot perform this role, the atrioventricular (AV) node may take-over pacemaking. When this occurs, the EKG will likely have distinctive waveform features that reveal important aspects of these junctional rhythms.
