Non-invasive mapping using the Cardio Insight system is performed in heart failure patients requiring biventricular pacing to optimize therapy, and understand mechanisms underlying pacing-induced cardiomyopathy and ventricular arrhythmias.
Non-invasive mapping using the Cardio Insight system is prospectively performed routinely in heart failure patients requiring cardiac resynchronization therapy. Control patients are included, requiring chronic permanent right ventricular pacing. Specific focus include: optimization of programming parameters, pacing-induced cardiomyopathy, ventricular arrhythmias, defibrillation threshold testing and electrical shocks.
