Delivery of an electrical current timed for delivery during the QRS complex is called defibrillation
Indicate whether the statement is true or false
F
Synchronized cardioversion is the delivery of a shock to the heart by means of a defibrillator to terminate a rapid dysrhythmia. A synchronized shock means that the shock is timed to avoid the relative refractory period of the cardiac cycle. On the ECG, this period occurs during the peak of the T wave to approximately the end of the T wave. Defibrillation is the delivery of an electrical current across the heart muscle over a very brief period to terminate an abnormal heart rhythm. Defibrillation is also called unsynchronized countershock or asynchronous countershock, because the delivery of current has no relationship to the cardiac cycle.
