The following are key points to remember from a review article on cardiac implantable electronic devices (CIEDs), which include pacemakers for bradycardia, biventricular pacemakers for heart failure, and implantable cardioverter–defibrillators (ICDs) for the treatment of sudden cardiac death:

Here is the transcript of the video: Implantable defibrillator is an important life saving device. Then, why is it mentioned that, implanting a defibrillator soon after an acute myocardial infarction, in those with left ventricular dysfunction and prone for ventricular arrhythmias and sudden cardiac death, is not useful?

The biopsy was consistent with cardiac sarcoidosis. She was given CRT-D (Cardiac Resynchronization Therapy-Defibrillator). SCD (sudden cardiac death) from sarcoid heart disease is thought to be caused by either from high-grade AV block or VT. Medical treatment with oral steroids and methotrexate was started.

The limb lead abnormalities appear to be part of the Brugada pattern, as described in this article: Inferior and Lateral Electrocardiographic RepolarizationAbnormalities in Brugada Syndrome Discussion Brugada Type 1 ECG changes are associated with sudden cardiac death (SCD) and the occurrence of ventricular dysrhythmias.

Regardless of further evaluation, she should avoid bradycardia, AV nodal blockers, Na channel blockers, and fevers. --If Fever not only unmasks a Brugada-type electrocardiogram (ECG) but also increases the risk of ventricular tachyarrhythmias such as ventricular fibrillation (VF) or sudden cardiac death.
