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.

Background Brugada syndrome (BrS) is a channelopathy that can lead to sudden cardiac death in the absence of structural heart disease. Patients with BrS can be asymptomatic or present with symptoms secondary to polymorphic ventricular tachycardia or ventricular fibrillation. The patient did not have underlying diseases.

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.

Shortly after isoprenalin infusion was initiated, there were short runs of ventricular tachycardia. The biopsy was consistent with cardiac sarcoidosis. She was given CRT-D (Cardiac Resynchronization Therapy-Defibrillator). She was started on isoprenalin (isoproterenol). The above ECG initially shows AV block.

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)

Since its identification in 1981 its diagnosis has increased due to the advancements in cardiac imaging. It’s association with ventricular arrythmia (VA) and sudden cardiac death (SCD) underscores the importance of its identification.

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a disease characterised by fibrofatty replacement of the ventricular myocardium due to specific mutations, leading to ventricular arrhythmias and sudden cardiac death. Emerging evidence suggests that combining flecainide and bisoprolol may be efficacious.
