Both of these features make inferior + RV MI by far the most likely ( Pseudoanteroseptal MI is another name for this ) There is also sinus bradycardia and t he patient is in shock with hypotension. A narrow complex bradycardia without any P-waves is also likely to respond to atropine, as it may be a junctional rhythm.

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:

Intraventricular conduction abnormalities (ICA) can progress without specific symptoms or occur after cardiac valve or ischemic heart interventions or surgeries, potentially causing severe bradycardia that may lead to falls or sudden cardiac death. To date, there is no appropriate way to predict this in advance.

Long QT syndrome is most commonly an inherited condition associated with a risk of sudden cardiac death. It is recognized that LQTS in the fetus may present as sinus bradycardia (SB), functional 2:1 atrioventricular block and ventricular arrhythmias (VA).

The granulomatous inflammation affects the heart, causing an infiltrative cardiomyopathy The most common manifestations of cardiac sarcoidosis are atrioventricular (AV) block and ventricular tachyarrhythmias (VT). SCD (sudden cardiac death) from sarcoid heart disease is thought to be caused by either from high-grade AV block or VT.

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? Mostly for protection against sudden cardiac death. So, this is how an ICD works.

The rule of thumb is less accurate, and the risk is higher because a long QT in the presence of bradycardia ("pause dependent" Torsades) predisposes to Torsades. 6) Use a different rule of thumb for bradycardia : Manually approximate both the QT and the RR interval. 3) At heart rates below 60, far more caution is due.
