This definition refers to localized activities without specifying the underlying ... the mechanism underlying the different types of electrograms using high density mapping (Rhythmia, Boston ...

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 ...

An increased burden of premature atrial contractions (PACs) has long been considered a benign phenomenon. However, strong evidence of their involvement in the occurrence of atrial fibrillation (AF), ...

Little is known with regard to the frequency of paroxysmal AF in MS. In 63 patients with MS in SR (mean age 49 years), 24 hours Holter ECG showed that 56% had paroxysmal supraventricular arrhythmias ...

Atrial fibrillation (AFib) is the most common form of irregular heartbeat (arrhythmia). People with AFib have many treatment options, including medications and medical procedures. However ...

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.

Therapies targeting this dysregulation have been actually developed. Figure 3. Twelve-lead ECG tracing during stress test shows the typical aspect of bidirectional ventricular tachycardia ...

Atrial fibrillation (AFib) can affect life expectancy due to factors that include age, underlying health conditions, race, and how this common cardiac arrhythmia—or abnormal heart rhythm— is treated.

Cardiac involvement has been predominantly noted in amyloid light chain (AL) amyloidosis (also known as primary amyloidosis), hereditary, senile, and isolated atrial amyloidosis ... but also requires ...

1 Frequent ventricular ectopic (VE) beats (or premature ventricular contractions (PVC)), non-sustained ventricular tachycardia (NSVT), and atrial fibrillation (AF) are the most common arrhythmias seen ...

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