This medical device was FDA approved on September 16, 2010. The Resynchronization Therapy Defibrillator (CRT-D) is an implantable (below the collar bone under the skin) medical device that is used for therapy – by delivering small electrical impulses to the heart. The pulses help synchronize heart beats.
The three leads of the medical device are placed: the right atrium (of the heart), the right ventricle and the last lead is placed on the coronary vein of the left ventricle.
The medical device senses and works to correct problems (abnormal heart rhythms) also know as arrhythmias.
An arrhythmia is a heart disorder that affects the rhythm of the heart. This can result if the heart beats come at abnormal pulses (i.e. irregular pattern) or if the heart beats too fast or too slow (bradycardia, tachycardia respectively).
