Supraventricular Tachycardia ECG Interpretation

ECG Strip

Supraventricular Tachycardia Rhythm Strip Features

Rate: Fast (150-250 bpm)
Rhythm: Regular
P Wave: Merged with T wave
PR Interval: Normal (0.12 sec)
QRS: Normal (.10 sec)
Occurs when a junctional rhythm exceeds 100 bpm. Cardiac complexes will be very close to one another. The T waves of the previous complex will cover the P wave of the next complex. P waves will be entirely buried
Supraventricular tachycardia (SVT) is a rapid heart rhythm originating at or above the AV node. SV rhythm rates are above 100 beats per minute and are typically 150-250 bpm. SVT is a common pediatric rhythm problem. SVT’s rapid heart rate does not allow the ventricles to completely fill with blood, decreasing cardiac output.
