By definition, multifocal atrial tachycardia must have at least three distinctly different P wave morphologies and a ventricular rate of greater than 100 beats per minute. Multifocal atrial ...

Ventricular tachycardia is an abnormally fast heart beat (with three or more consecutive heart beats at least 100 beats per minute) that originates from one of the ventricles in the heart.

Multifocal atrial tachycardia — or MAT — is a rhythm that frequently occurs in the setting of severe lung disease. MAT is characterized by three different P-wave morphologies within one 10 ...

Most people with sinus tachycardia have little to no symptoms, but some experience heart palpitations, chest pain, and dizziness. Supraventricular and ventricular tachycardia, on the other hand ...

Background: Only a few algorithms for predicting the site of origin of focal atrial tachycardia (AT) have been reported. We aimed to develop a new and more effective algorithm. Methods ...

Such techniques can be automatically applied using implantable cardioverter defibrillators (ICDs) and offer the potential for painless termination of ventricular tachycardia (VT). Reduction in ...

FieldForce is the first PFA system specifically designed for the ablation treatment of ventricular tachycardia (VT ... with a next-generation, focal PFA tool for fast, accessible VT care." ...
