Supraventricular tachycardia (SVT)
- Stable regular narrow-complex SVT → vagal maneuvers
- Adenosine is first-line acute drug
- Beta blocker/non-DHP CCB are alternatives
- Unstable SVT → synchronized cardioversion
- Recurrent symptomatic SVT → catheter ablation
- Avoid AV-node blockers in pre-excited AF
