Sudden cardiac death accounts for more than 300,000 cardiac events in the United States alone each year, representing 50% of all cardiovascular deaths. 115 Although resuscitation rates vary widely, most patients do not survive an out-of-hospital cardiac arrest. Thus, there is a major need to identify noninvasive diagnostic tests to screen patients at risk in broad populations and to provide potentially direct therapeutic interventions. To date, no individual technique as a gold standard has been identified with sufficient sensitivity and specificity to allow for accurate risk prediction. The purpose of this article is to examine the theoretic basis and data regarding risk-stratification techniques for patients with ventricular arrhythmias.
