Quizplus · Accepted Answer

Interpolation PVCs are considered benign and do not indicate increased myocardial irritability. They occur when the premature beat falls within the refractory period of the preceding beat, causing the sinus node to reset and resulting in a normal-looking QRS complex. However, couplets, runs, bigeminy, trigeminy, quadrigeminy, and R on T phenomenon are all considered warning signs of increased myocardial irritability and require further investigation.
