Supraventricular Tachycardia - Course # 314-12
- Supraventricular tachycardia 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 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 making it impossible to describe their morphology and measure the PR interval.
- Analyze this tracing using the five steps of rhythm analysis.
- Compare your answers with the answers on the next slide.
- Rhythm: Regular
- Rate: 200
- P wave: Buried
- PR interval: Unable to measure
- QRS: 0.06 sec
- Interpretation: Supraventricular Tachycardia
