Experimental
External Electrocardioversion
Internal Electrocardioversion
Cardioversion with an external cardioverter-defibrillator with a step-up energy protocol (100, 150, 200, 360 J biphasic) in antero-posterior orientation, maintaining a > 8 cm distance between shock electrodes and device and complying with a "cool-down" phase of 2 minute between shocks, if more than one shock is required.
Cardioversion via the implanted ICD with a maximum energy synchronized shock (41 J, with a RV -> SVC+can shock orientation in pts with SVC leads). After 1 ineffective internal shock, the patient will be counted as internal CV failure and cardioverted externally, following the same protocol as the external CV group.
