Ventricular tachycardia is a potentially life threatening cardiac arrhythmia. On the ECG, ventricular tachycardia can be defined as three or more ventricular ectopic beats occurring in a sequence at a rate more than 100 per minute. Another rare form of ventricular tachycardia is bidirectional ventricular tachycardia.

This is the shock coil and identifies this device as a defibrillator. CRT-D is cardiac resynchronization therapy with defibrillation capability, like the CXR above. CRT-P is cardiac resynchronization therapy with pacing only, without the ability to defibrillate. So the most likely rhythm in ECG 1 is ectopic atrial tachycardia.

Tetralogy of Fallot (TOF) represents the poster child for monomorphic ventricular tachycardia (MVT) in congenital heart disease. Sustained MVT affects approximately 10% of such patients at 30 years after cardiac repair and is inextricably related to the burden of sudden cardiac death (SCD).(1)

Intrinsic antitachycardia pacing (iATP) may be beneficial both as first-line and secondary therapies to terminate ventricular tachycardia (VT) effectively in comparison with conventional antitachycardia pacing (ATP). However, the clinical efficacy of iATP in comparison with conventional ATP is unknown.

Patients with repaired tetralogy of Fallot are at risk of ventricular tachycardia (VT) and sudden cardiac death. Historically, risk stratification electrophysiologic studies involved programmed ventricular stimulation with VT induction guiding implantable cardioverter-defibrillator (ICD) implantation or VT ablation.

ABSTRACT The extravascular implantable cardioverter-defibrillator (EV-ICD) was developed to overcome complications associated with transvenous leads while being able to deliver anti-tachycardia pacing (ATP). The lead is implanted in the substernal space, which makes extraction a cautious procedure.

Progressive decline across periods in mortality rates among patients with implantable cardioverter-defibrillator (ICD). Chagas disease (ChD) was associated with increased rates of ventricular tachycardia and ventricular fibrillation in ICD patients only in the initial two periods, but there was no statistical difference in the last period.
