RESUMO
Objective To analyze 5 patients suptered heart failure and ventricular tachycardia((VT).)Methods The Implantable Biventricular pacing cardioverter defibrillator was used to analyzed 5 patients(4 with primary dilated cardiomyopathy and 1 with coronary heart disease) suffered from heart failure and ventricular tachycardia(VT).Results 2 cases had history of syncope,4 patients were implanted INSYNC 7272 implantable cardioverter defibrillator(ICD) and 1 patient was implanted V-350 ICD.During the 1~14 month follow-up period,all the cardio functions were improved without VT or syncope.1 patient with VT and VF was detected and terminated by ICD.The patient was saved.Conclusions Implantable biventricular pacing cardioverter defibrillator is an effective approach to treat sudden cardiac death,mortal ventricular arrhythmia and heart failure.
