Premature ventricular contractions are considered precursors of ventricular tachycardia when they a) occur at a rate of more than six per minute. When PVCs occur at a rate of more than six per minute they indicate increasing ventricular irritability and are considered forerunners of ventricular tachycardia (VT). b) occur during the QRS complex. PVCs are dangerous when they occur on the T wave. c) have the same shape. PVCs are dangerous when they are multifocal (have different shapes). d) are paired with a normal beat. A PVC that is paired with a normal beat is termed bigeminy.
