When your electrical system is working normally, the two upper chambers of the heart (atria) contract and pump blood into the two lower chambers (ventricles) in a well-coordinated way. This results in ...

Atrial flutter and atrial fibrillation (AFib) both occur when the electrical signals that make your heart chambers contract occur faster than typical. However, they differ in the organization of ...

3. Premature supraventricular beat with aberrancy (left bundle branch block pattern). Multifocal atrial tachycardia (MAT) occurs when multiple areas (ectopic foci) within the atrium generate ...

At times it is difficult to distinguish atrial fibrillation from atrial flutter on the ECG. This example shows coarse "fibrillatory waves" in the setting of atrial fibrillation. This are of varying ...

A new study has linked prolonged P-wave duration to increased risk for sudden cardiac death (SCD), independent of cardiovascular risk factors and atrial fibrillation. 1 This suggests P-wave duration ...

April 12, 2004 — Lone atrial flutter (ie, the occurrence of atrial flutter in patients without underlying heart disease) is associated with an increased risk of thromboembolism and subsequent ...

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 ...
