ABSTRACT:
Methods, circuits and devices useful for maximizing the likelihood of successful defibrillation or cardioversion using an automatic implantable cardioverter/defibrillator ("AICD") system are provided which are capable of monitoring the impedance of AICDs for purposes of detecting lead malfunctions. After detection of a lead malfunction, the methods, circuits and devices are capable of connecting or disconnecting leads and electrodes to maximize the likelihood of effective cardioversion and defibrillation.
