MI Related Malignant Ventricular Arrhythmia
Conditions
Keywords
myocardial infarction, ventricular arrhythmia, radiofrequency ablation, Coronary Artery Bypass Grafts
Brief summary
Patients with myocardial infarction related potential malignant ventricular arrhythmia have high risk of sudden death. The aim of this clinical trial is evaluating therapeutic efficacy of unipolar or bipolar radiofrequency ablation in Coronary Artery Bypass Grafts (CABG) Surgery, which can reduce myocardial ischemia and block reentry circuits of ventricular arrhythmia at the same time. The observation indexes include the morbidity of potential malignant ventricular arrhythmia and major adverse cardiovascular events in mid-long-term after CABG surgery.
Interventions
Patients with myocardial infarction related potential malignant ventricular arrhythmia undergoing unipolar or bipolar radiofrequency ablation and Coronary Artery Bypass Grafts at the same time
Patients with myocardial infarction related potential malignant ventricular arrhythmia undergoing Coronary Artery Bypass Grafts
