Overview

There are several other diagnostic tests being done for sudden cardiac death. These include the signal-averaged electrocardiogram, exercise testing, provocative diagnostic tests such as the sodium channel blocker testing, adenosine test, and epinephrine test, electrophysiology study, and genetic testing [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [6] [15] [16] [17].

2017AHA/ACC/HRS Guideline for management of sudden cardiac arrest and ventricular arrhythmia

[19]

Class I, Level of evidence:B
In patients who recovered from SCA due to ventricular arrhythmia suspected ischemic heart disease, coronary angiography and probabley revascularization is recommmended
Class I, Level of evidence:C
In patients with anomalous origin of a coronary artery leading ventricular arrhythmia or SCA, repair or revascularization is recommended
Class IIa, Level of evidence:B
In patients with ischemic or nonischemic cardiomyopathy or congenital heart disease presented with syncope arrhythmia and do not meet criteria for primary prevention ICD, an electrophysiological study is recommended for assessing the risk of sustained VT
Class III, Level of evidence:B
In patients who meet criteria for ICD implantation, an electrophysiological study is not recommended for only inducing ventricular arrhythmia
Class III, Level of evidence:B
An electrophysiological study is not recommended for risk stratification for ventricular arrhythmia in patients with Long QT syndrome, short QT syndrome, cathecolaminergic polymorphic ventricular arrhythmia




Class I (Level of Evidence: C)
  • In patients with SCA or SCD in their family member, genetic tests and genetic counselling is recommended
