Definitions
- Supraventricular tachycardia (SVT)
- Any tachycardia with its origin above ventricles
- Rates typically > 200 beats per minute (BPM)
- May have 1:1 atrioventricular (AV) conduction or variable degree of heart block (e.g., 2:1)
- Types
- Automatic rhythms
- Sinus tachycardia
- Atrial ectopic tachycardia
- Reentrant rhythms
- AV reentry
- Atrial flutter
- Automatic rhythms
- Ventricular tachycardia
- Ventricular rate exceeds atrial rate
- Supraventricular tachycardia (SVT)
