Supraventricular Tachycardia - Junctional Dysrhythmia.
- 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.
- Rhythm: Regular
- Rate: 200
- P wave: Buried
- PR interval: Unable to measure
- QRS: 0.06 sec
- Interpretation: Supraventricular Tachycardia
