Dear Mayo Clinic: Recently, I was diagnosed with ventricular tachycardia, but doctors said a cause cannot be determined. What usually causes this problem? Does knowing the cause make a difference in ...

Ventricular tachycardia is when the lower chamber of the heart beats too fast to pump efficiently. A common heart rate with VT is around 150 to 250 beats per minute. VT can occur due to conditions ...

In patients without established cardiac disease, the occurrence of premature ventricular complexes without sustained ventricular tachycardia is more an annoyance than a medical risk, and treatment is ...

This ECG (Figure 1), recorded in the emergency room, shows a wide complex tachycardia at 205 bpm. Wide complex tachycardias are more likely to be ventricular tachycardia (VT) than supraventricular ...

Ventricular tachycardia arises from an abnormal electrical focus or circuit in the myocardium of the ventricle and is usually manifested as a tachyarrhythmia with a wide QRS complex on ...

Patients with structural heart disease are at risk for life-threatening ventricular tachycardias (VTs). Implantable cardioverter-defibrillators (ICDs) can terminate VT, but often at the cost of ...

A new multicenter trial has used a new ablation technique for patients with ventricular tachycardia, an abnormally rapid heart rhythm that is a leading cause of sudden cardiac death worldwide. A first ...

Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT) is a rare genetic ventricular tachycardia which can result in sudden cardiac death and/or syncope in young individuals with structurally ...

The incidence of ventricular fibrillation or pulseless ventricular tachycardia as the first recorded rhythm after out-of-hospital cardiac arrest has unexpectedly declined. The success of ...

Thermedical®, a developer of advanced thermal-ablation technologies, today announced the members of the independent data ...

Verapamil sensitive ventricular tachycardia is a form of idiopathic ventricular tachycardia that occurs with a structurally normal heart arising from the left posterior fascicle. This manifests as a ...
