Recommendations and Levels of Evidence for Therapy for VT Associated With Organic Heart Disease
| COR | LOE | GOR (MINDS) | LOE (MINDS) | |
|---|---|---|---|---|
| Immediate direct‐current defibrillation in the patients with sustained hemodynamically unstable VT | I | B | A | III |
| Use of ICD for recurrent VT and prevention of sudden cardiac death | I | A | A | I |
| Catheter ablation for drug‐resistant VT due to IHD * | I | B | A | II |
| Intravenous administration of amiodarone or nifekalant for resuscitation in patients with sustained or recurrent hemodynamically unstable VT after direct‐current defibrillation | IIa | A | B | II |
| Intravenous administration of procainamide for termination of hemodynamically stable monomorphic sustained VT | IIa | A | B | II |
| Use of oral amiodarone or sotalol for recurrence of VT | IIa | A | A | II |
| Intravenous administration of amiodarone for termination of hemodynamically stable polymorphic sustained VT | IIb | A | C1 | II |
*
Indication of catheter ablation is the same as in the “Guideline for Non‐pharmacotherapy of Cardiac Arrhythmias”. 3
