Guidant CONTAK RENEWAL 4 AVT (model M170). Cardiac Resynchronization Therapy Defibrillator (CRT-D). Sterile EO. Guidant Corporation, 4100 Hamline Avenue North, St. Paul, MN 55112-5798 USA. Cardiac resynchronization therapy defibrillators (CRT-D) provide both atrial and ventricular tachyarrhythmia and cardiac resynchronization therapies. Ventricular tachyarrhythmia therapy is for the treatment of ventricular tachycardia (VT) and ventricular fibrillation (VF), rhythms that are associated with sudden cardiac death (SCD). Atrial tachyarrhythmia therapy is for the treatment of supraventricular tachcardia (SVT) and atrial fibrillation (AF). Cardiac resynchronization therapy is for the treatment of heart failure (HF) and uses biventricular electrical stimulation to synchronize ventricular contractions. This device also uses accelerometer-based adaptive-rate bradycardia therapy. Cardioversion/defibrillation therapies include a range of low-and high-energy shocks using either a biphasic or monophasic waveform.
