[Ventricular tachycardia and premature ventricular contraction] |
Ventricular tachycardia is defined as a sudden rapid heart beat that originates in a ventricle. Subjective symptoms can include palpitations, vertigo, or fainting. It can be largely classified as either idiopathic ventricular tachycardia (no underlying cardiac disorder) or ventricular tachycardia with organic heart disease (e.g. myocardial infarction). |
1) Idiopathic ventricular tachycardia
Idiopathic ventricular tachycardia can derive either from the right or left ventricle. The main complaint is a suddenly occurring palpitation, but the prognosis is good. |
2) Ventricular tachycardia with organic heart disease
This type of tachycardia is complicated by a previous myocardial infarction or myocardiopathy. Subjective symptoms can include palpitations and vertigo or, in a severe case, ventricular fibrillation that can lead to sudden death. |
