Scar-related monomorphic ventricular tachycardia is the most common type and a frequent cause of death in patients having survived a heart attack, especially if they have weak heart muscle. [ 12 ] Right ventricular outflow tract (RVOT) tachycardia is a type of monomorphic ventricular tachycardia originating in the right ventricular outflow tract .
But ventricular tachycardia’s different than, say, a fast heart rate from exercising, which is called as “sinus tachycardia”. Normally, the electrical signals that generates each heart beat starts in the right atrium, at the sinus node, also known as the sinoatrial node or the SA node, if the rate goes over 100 bpm and originates in the ...
Ventricular tachycardia (VT or V-tach) is a potentially life-threatening cardiac arrhythmia that originates in the ventricles. It is usually a regular, wide complex tachycardia with a rate between 120 and 250 beats per minute.
This tissue allows the electrical impulse, which stimulates the heartbeat, to happen very rapidly. Right ventricular outflow tract tachycardia is the most common type of ventricular tachycardia in otherwise healthy individuals. This defect is due to an electrical node in the right ventricle just before the pulmonary artery.
These are typically a form of ventricular tachycardia known as Torsades de pointes which can cause faints, seizures, or even sudden death. [1] Less dangerous arrhythmias such as atrial fibrillation also occur, causing symptoms of heart racing or palpitations. However, many of those with Romano–Ward syndrome will remain free from arrhythmias ...

Torsades de pointes, torsade de pointes or torsades des pointes (TdP; also called torsades) (/ t ɔːr ˌ s ɑː d d ə ˈ p w æ̃ t /, [2] French: [tɔʁsad də pwɛ̃t̪], translated as "twisting of peaks") is a specific type of abnormal heart rhythm that can lead to sudden cardiac death. It is a polymorphic ventricular tachycardia that ...
In childhood hypertrophic cardiomyopathy, previous adverse cardiac events, non-sustained ventricular tachycardia, syncope, and left ventricular hypertrophy have been shown to predict sudden cardiac death. [161] Other causes can include drugs, such as cocaine and methamphetamine, or overdose of medications, such as antidepressants. [30]
