Who can join
Ages 18 and older · All sexes
Full eligibility criteria
Inclusion Criteria: * Diagnosis of ischemic cardiomyopathy * Single or dual chamber implantable cardioverter-defibrillator (ICD) Exclusion Criteria: * Non-Ischemic cardiomyopathy * Contraindication to catheter ablation * Severe peripheral arterial disease or medical condition that prohibit arterial access * Ventricular tachycardia (VT) or sudden cardiac arrest (SCA) within 30 days of acute coronary syndrome or within 90 days of coronary revascularization
About the study
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.
