WebVentricular tachycardia is a regular fast heartbeat which starts from the ventricles (pumping chambers) instead of starting from the SA node in the atria. Due to the speed of contraction and the origin of the beat, the heart may not have time to fully fill with blood before pumping. WebMonomorphic ventricular tachycardia means that the appearance of all the beats match each other in each lead of a surface electrocardiogram (ECG). 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]

Monomorphic ventricular tachycardia - Medical Dictionary

WebMonomorphic ventricular tachycardia is treated with synchronized cardioversion. Synchronization avoids the delivery of a LOW ENERGY shock during cardiac repolarization (t-wave). If the shock occurs on the t-wave (during repolarization), there is a high likelihood that the shock can precipitate VF (Ventricular Fibrillation). Web1. Tachyarrhythmias. Sustained ventricular tachycardia with a duration of greater than 3 seconds or symptomatic nonsustained ventricular tachycardia commonly causes presyncope or syncope. Amiodarone can be used in patients with structural heart disease, but an implantable cardioverter defibrillator may be necessary. WebWhat is ventricular tachycardia? Ventricular tachycardia (VT or V-tach) is a type of abnormal heart rhythm, or arrhythmia. It occurs when the lower chamber of the heart beats too fast to pump well and the body doesn't receive enough oxygenated blood. teacher with white dress
