Patients do not meet the evidence based ICD implantation criteria if they have (1) a myocardial infarction within 40 days before ICD implantation; (2) newly diagnosed heart failure at the time of ICD implantation without prior therapy; (3) NYHA class IV symptoms of congestive heart failure.

A seperate chapter deals with a more complete list of [[ICD indications]]

*Right ventricular lead
*Left ventricular lead (positioned in the coronary sinus)
*Left ventricular lead. The left ventricular lead is usually positioned in the coronary sinus, alternatively it can be positioned epicardially on the left ventricle (by a surgical procedure) or intracardially in the left ventricle (through a transseptal puncture).
 
===Programming, follow up and complications===
===Programming, follow up and complications===
Programming should specifically aim at ensuring atrial-synchronous permanent biventricular pacing, by performing AV-interval optimization (echocardiography guided or using invasive haemodynamic measurments) and performing ventricular-ventricle (VV) interval optimization. Further programming, follow up and complications are similar to pacemakers and ICDs (see above).
