The implantable cardioverter defibrillator (ICD) represents an important development in the effort to reduce the incidence of sudden cardiac death (almost 400,000 yearly in the United States). Early generation ICDs, which required epicardial lead systems and abdominal placement of the pulse generator, have been replaced by transvenous leads and pectoral implants. Other important refinements, which include biphasic waveforms, extensive memory capability, antitachycardia pacing, and enhanced sensing algorithms, have greatly improved patient tolerance. Ongoing trials and those in the planning stages will continue to expand the indications for ICDs and will focus on cost-effectiveness.

D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D001145	Arrhythmias, Cardiac	Any disturbances of the normal rhythmic beating of the heart or MYOCARDIAL CONTRACTION. Cardiac arrhythmias can be classified by the abnormalities in HEART RATE, disorders of electrical impulse generation, or impulse conduction.	Arrhythmia,Arrythmia,Cardiac Arrhythmia,Cardiac Arrhythmias,Cardiac Dysrhythmia,Arrhythmia, Cardiac,Dysrhythmia, Cardiac
D016757	Death, Sudden, Cardiac	Unexpected rapid natural death due to cardiovascular collapse within one hour of initial symptoms. It is usually caused by the worsening of existing heart diseases. The sudden onset of symptoms, such as CHEST PAIN and CARDIAC ARRHYTHMIAS, particularly VENTRICULAR TACHYCARDIA, can lead to the loss of consciousness and cardiac arrest followed by biological death.

D017147	Defibrillators, Implantable	Implantable devices which continuously monitor the electrical activity of the heart and automatically detect and terminate ventricular tachycardia (TACHYCARDIA, VENTRICULAR) and VENTRICULAR FIBRILLATION. They consist of an impulse generator, batteries, and electrodes.
