About this trial
The purpose of this study is to understand why certain hearts have ventricular arrhythmias and help identify areas of the heart that cause arrhythmias. There is still a significant gap in understanding why ventricular arrhythmias occur. This study will examine the electrical properties of the heart tissue to understand how these arrhythmias occur, and hopefully identify areas that might lead to ventricular arrhythmias. The hope is that studying this might be able to improve outcomes during ventricular tachycardia (VT) ablations.
