Tang et al. developed an algorithm to distinguish left and right atrial foci, and pioneered the prediction of focal ATs using surface P waves. [10] They reported that a positive P wave in lead V1 was ...

PHILADELPHIA — Accelerometer-based atrial sensing with a novel, enhanced, automated algorithm in patients with atrioventricular block and a single-chamber leadless pacemaker in the right ventricle ...

Atrial tachycardia is an unusually fast heartbeat that originates in the atria, or upper chambers, of the heart. It is a type of supraventricular tachycardia (SVT). This means it begins above the ...

The retrospective study population included 61 patients (29 men) with a mean age of 42 ± 5 years. Echocardiography showed normal LA (33.4 ± 1.5 mm) and normal ejection fraction (63.1 ± 2.3%). Two ...

Atrial tachycardia is an abnormal heart rhythm where the top chambers in your heart beat quicker than usual. During an atrial tachycardia episode, your heart rate may exceed 100 beats per minute (bpm) ...
