Supraventricular Tachycardia ECG Interpretation #314
Supraventricular Tachycardia
- Supraventricular tachycardia (SVT) occurs when the heart rhythm occurs as a result of electrical impulses initiated above the ventricles at a rate of 150 - 250 bpm or more.
- What will remain will be a normal appearing and measuring QRS complex depolarizing at a rapid rate.
- As a result of the rapid rate, the SVT ECG complexes will be very close to one another.
- The T waves of the previous SVT rhythm complex will cover the P wave of the next complex. P waves will be entirely buried making it impossible to describe their morphology and measure the PR interval.
