Some findings in standard electrocardiogram (ECG) may be associated with paroxysmal atrial fibrillation (AF). The aim of the study was to evaluate P wave duration and P wave dispersion (Pdysp) derived from 12-lead standard surface ECG in sinus rhythm in patients with history of AF in comparison to control subjects without AF and with premature ventricular ectopic beats (PVEB). The study group consisted of 20 patients (pts), 9M. 11F, mean age 47.6 +/- 5.5 years with paroxysmal AF. The control group consisted of 19 pts, 9M, 10F, mean age 46.7 +/- 4.7 years without history of AF with PVEB. All patients in both groups were treated with antiarrhythmic drugs. Left atrium dimensions (LA) in the transthoracic echocardiographic examinations (TTE) and maximal (P(max)), minimal (P(min)) wave duration and P(dysp) in a ECG recordings were analyzed. Pdysp was calculated as the difference between P(max) and P(min). ECG analysis showed statistically significant differences, study group vs control group in P wave duration and P(dysp). We found that in AF group P(max) and P(dysp) were significantly greater (125.5 vs. 114.5 ms, p < 0.005 and 59.5 vs 45.4 ms, p < 0.01, respectively). LA were significantly greater in AF group (43.7 vs 41.8 mm, p < ...Continue Reading

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Anti-Arrhythmic Drug Therapies

Anti-arrhythmic drugs are used to prevent abnormal heart rhythms. These medications are used in conditions including, ventricular tachycardia, ventricular fibrillation and atrial fibrillation. Discover the latest research on anti-arrhythmic drug therapies here.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.


Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Antiarrhythmic Agents: Mechanisms of Action

Understanding the mechanism of action of antiarrhythmic agents is essential in developing new medications as treatment of cardiac arrhythmias is currently limited by the reduced availability of safe and effective drugs.
