Overview

ECG is the first diagnostic test that should be obtained in hemodynamically stable Ventricular tachycardia. For detection of tachyarrhythmia symptoms related exercise such as cathecolaminergic polymorphic VT, Exercise stress test is recommended. Findings on resting ECG associated with diagnosis of VT include evidence of structural hear disease such as prior MI or chamber enlargement, evidence of inherited arrhythmia disorders such as long QT syndrome, Brugada syndrome, arrhythmogenic right ventricular cardiomyopathy. QRS duration and conduction abnormality may have prognostic value in structural heart disease.

Diagnostic Study of Choice

2017 AHA/ACC/HRS Guidelines for Management of Patients With Ventricular Arrhythmias

Class I
"In patients with sustained, hemodynamically stable, wide QRS tachycardia , 12 leads ECG should be obtained (Level of Evidence B)"
"In patients with exercise induced ventricular tachyarrhythmia such as IHD or cathecolaminergic polymorphic VT, exercise treadmill test is recommended (Level of Evidence B)"
"In patients with suspected or documented VT, 12 leads ECG during sinus rhythm should be obtained for detecting structural heart disease (Level of Evidence B)"
" Ambulatory electrocardiogram monitoring is recommended for patients presented with palpitation, syncope, presyncope suspected ventricular arrhythmia (Level of Evidence B)"
  1. Evidence of structural hear disease such as prior MI or chamber enlargement
  2. Evidence of inherited arrhythmia disorders such as long QT syndrome, Brugada syndrome, arrhythmogenic right ventricular cardiomyopathy
