why is r on t dangerous?
What does r on t mean in ECG?
The " R-on-T phenomenon" is the superimposition of an ectopic beat on the T wave of a preceding beat. Early observations suggested that R-on-T was likely to initiate sustained ventricular tachyarrhythmias.

Why is R on T PVC a major concern?
PVCs may occur early in the cycle ( R-on-T phenomenon ), after the T wave (as seen above), or late in the cycle - often fusing with the next QRS (fusion beat). R-on-T PVCs may be especially dangerous in an acute ischemic situation, because the ventricles may be more vulnerable to ventricular tachycardia or fibrillation.

Why is the R on T premature ventricular complex PVC of major concern quizlet?
When premature ventricular contraction ( PVC ) falls on the T wave of the preceding beat, R -on- T phenomenon occurs. Because the ventricle is repolarizing and there is increased excitability of cardiac cells, there is an increased risk of ventricular tachycardia or ventricular fibrillation.
