Overview
Ischemic heart disease is the most common cause of ventricular tachycardia. VT causes approximately 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.
Epidemiology
- Between 2005-2013, the incidence of vetricular arrhythmia associated cardiomyopathy was estimated to be 28800 cases per 100,000 individuals in Minnesota.[1]
- Age
- The prevalence of [disease name] is approximately [number or range] per 100,000 individuals worldwide.
- In [year], the incidence of [disease name] was estimated to be [number or range] cases per 100,000 individuals in [location].
- Age
- Patients of all age groups may develop [disease name].
- [Disease name] is more commonly observed among patients aged [age range] years old.
- Ideopathic Ventricular tachycardia is more commonly observed among elderly patients.
- Gender
- [Disease name] affects men and women equally.
- Females are more commonly affected with ideopathic VT than men.[1]
- The [gender 1] to [Gender 2] ratio is approximately [number > 1] to 1.
- Race
- There is no racial predilection for [disease name].
- [Disease name] usually affects individuals of the [race 1] race.
- [Race 2] individuals are less likely to develop [disease name].
- Sustained ventricular tachycardia (VT) is an important cause of 150,000 to 300,000 out of hospital sudden deaths that occur annually in the US.[2]
- The most common cause of wide complex tachycardia (WCT) is ventricular tachycardia (VT), which accounts for 80% of all cases of WCT.[3]
- Supraventricular tachycardia (SVT) with aberrancy accounts for 15,000 to 20,000 in every 100,000 of WCTs.
- SVTs with bystander preexcitation and antidromic atrioventricular reentrant tachycardia (AVRT) account for 1000 to 6000 in every 100,000 of WCTs.[4]
- However, the underlying substrate varies: ischemic heart disease in 75,000-85,000 in every 100,000 cases; idiopathic cardiomyopathy in 1000-1500; and 1000-2000 in every 100,000 due to rare monogenic mutations in cardiac ion channels or associated proteins.[5]
- Brugada Syndrome may account for up to 50% of all SCDs in young individuals without structural heart disease. [5]
Demographics
Age
- VT is unusual in children but may occur in the postoperative cardiac setting or in patients with associated congenital heart disease.[6]
- Tachydysrhythmias in children is more commonly due to paroxysmal supraventricular tachycardias (PSVTs).
- The incidence of ischemic VT increases with age.
- VT rates peak in the middle decades of life.
- Idiopathic VT can be observed at any age.
- Men are more commonly affected by ventricular tachycardia than female, because ischemic heart disease is more prevalent in men.[7]
- Females with acquired or congenital long QT syndromes are at greater risk for sudden death.
