sudden cardiac death
implantable cardioverter defibrillator
The majority of sudden cardiac death （SCD） is caused by fatal arrhythmias （brady-and tachyarrhythmia）, most of leading to SCD are tachy-arrhythmias like ventricular tachycardia （VT） or ventricular fibrillation （VF）.
Implantable cardioverter defibrillator （ICD） therapy to VT and VF is dramatically demonstrating improved survival from SCD by randomized clinical trials. Today’s ICD devices are implanted pectorally with transvenous lead in most patients, so procedures can be done by physician （duration of procedure １-２ hrs）.
We had performed ICD therapy to forty-two patients including with low left ventricular function. Although all patients could leave hospital, several patients died of heart failure and suffered from inappropriate therapy. In patients with advanced heart failure, cardiac-resynchronization therapy may decrease the risk of death from heart failure, when combined with ICD.
Resynchronization therapy may have clinical benefit, especially when combined with an implantable defibrillator.
