[[Ischemic heart disease]] is the most common cause of ventricular tacchycardia in the US, followed by [[cardiomyopathy]]. VT causes approximately of half of the 300,000 [[sudden deaths]] which occur out of hospital annually in the US. [[Brugada syndrome]] is thought to be the cause of half of the sudden cardiac deaths which occurs in young individuals without structural heart disease.
[[VT]] is more prevalent among [[patients]] with [[coronary artery disease]]. Eldery [[patients]] are more commonly affected by ideopathic [[VT]]. Ideopathic [[VT]] is commonly observed in [[women]].There is no racial predilection for [[VT]].

* Sustained [[ventricular tachycardia]] (VT) is an important cause of 150,000 to 300,000 out of hospital [[sudden death]]s that occur annually in the US.<ref name="pmid19768192">{{cite journal| author=Stevenson WG| title=Ventricular scars and ventricular tachycardia. | journal=Trans Am Clin Climatol Assoc | year= 2009 | volume= 120 | issue=  | pages= 403-12 | pmid=19768192 | doi= | pmc=PMC2744510 | url= }} </ref>


* The most common cause of [[wide complex tachycardia]] ([[WCT]]) is [[ventricular tachycardia]] ([[VT]]), which accounts for 80% of all cases of [[WCT]].<ref name="pmid11233948">{{cite journal| author=Gupta AK, Thakur RK| title=Wide QRS complex tachycardias. | journal=Med Clin North Am | year= 2001 | volume= 85 | issue= 2 | pages= 245-66, ix-x | pmid=11233948 | doi= | pmc= | url= }} </ref> 
*[[Supraventricular tachycardia]] (SVT) with aberrancy accounts for 15% to 20% of WCTs.

* However, the underlying substrate varies: [[ischemic heart disease]] in 75–80% cases; idiopathic [[cardiomyopathy]] in 10–15%; and 1–2% due to rare monogenic [[mutation]]s in [[cardiac]] [[ion channels]] or associated proteins.<ref name="book2"> Zipes DP, Jalife J(2009).
