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.
Supraventricular tachycardia, or SVT, is far different than the rhythms discussed above, which originate in the ventricles. Patients in a supraventricular tachycardia will have a rapid rhythm with a heart rate greater than 150 beats per minute.ine v-fib is sometimes mistaken for asystole. As the treatments for asystole and ventricular fibrillation are different, it is important to differentiate between the two. If in doubt, it is acceptable to deliver a shock.
