ARRHYTHMIAS-POLYMORPHIC VT MGM

SUMMARY

1. Stable: give amiodarone; haemodynamically compromised: shock. For refractory VT: give amiodarone. Ensure QT not prolonged prior to giving amiodarone.

2. IV beta-blockers if ischemia is suspected or cannot be excluded.

3. Urgent cath if ischemia is suspected.

4. Assess for torsades de pointes.

5. Never use verapamil as 30% of those with VT rapidly deteriorate.
