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.
Junctional rhythms occur when the AV node takes over as the primary pacemaker site in the heart either because the SA node has failed or the AV node is going faster and over takes the SA node. Junctional rhythms are classified as follows: Juntional Rhythm, rate is 40-60 beats per minute.
