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.

Sinus tachycardia – sinus rhythm above 100 bpm is a sinus tachycardia. Sinus bradycardia – sinus rhythm below 60 bpm is a sinus bradycardia. Ventricular tachycardia – more than 7 consecutive complexes originating from ventricles at a rate of > 100 bpm. Usually does not exceed 160 bpm.

He denied any known medical history, specifically: coronary artery disease, hypertension, dyslipidemia, diabetes, heart failure, myocardial infarction, or any prior PCI/stent. Breath sounds were clear in all lung fields. No appreciable skin pallor. He reported to be a social drinker, but used tobacco products daily.

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.

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? Then, why is it mentioned that, an implantable defibrillator, is not useful, soon after myocardial infarction?

There is also bradycardia. Bradycardia puts patients at risk for "pause-dependent" Torsades de Pointes. Torsades in acquired long QT is much more likely in bradycardia because the QT interval following a long pause is longer still. See here for management of Polymorphic Ventricular Tachycardia , which includes Torsades.

Automatic activity refers to enhanced pacemaking function (typically from a non sinus node source), for example atrial tachycardia. AIVR is not always the result of significant pathology, but is classically associated with the reperfusion phase of acute myocardial infarction. Do not treat AIVR. Am Heart J 1999;137:799–805.
