Abstract
|
|
|
|
A 57-year-old man was admitted to our institution with frequent implantable cardioverterdefibrillator (ICD) shock. The ICD was implanted for aborted sudden cardiac death due to nonischemic cardiomyopathy. Recurrent ventricular tachycardia (VT) was suspected, so an electrophysiological study was performed. Four types of VT were induced and delayed potential mapping visualized a critical isthmus. Successful ablation was performed and VT was no longer induced
