Task: Answer Verification
Input (English): Question: Do multiple monophasic shocks improve electrotherapy of ventricular tachycardia in a rabbit model of chronic infarction?
Answer: Maintenance of shock-induced virtual electrode polarization by multiple monophasic shocks over a VT cycle is responsible for unpinning of reentry leading to self-termination. Elimination of virtual electrode polarization by shock polarity reversal during multiple biphasic shocks proved ineffective. A significant reduction in CVT can be achieved by applying multiple monophasic shocks within one VT CL or one single shock at the proper coupling interval.
Output (English): yes
