This is fortuitous, since automatic ectopic rhythms often have a rate that is the same or almost the same as that of the existing sinus rhythm. 11. Atrial Flutter.

The possibility that ectopic ventricular rhythms, particularly ventricular tachycardia and fibrillation, result from pacemaker stimuli that arise at the vulnerable period of the cardiac cycle has ...

The second ECG strip below shows an ectopic atrial rhythm. Note that the P wave is down in lead II and only up (not biphasic) in lead V1. Ectopic atrial rhythms including atrial tachycardia, ...

Women with circadian rhythm misalignment may be at a greater risk for developing ovarian endometriosis, according to data presented at the European Congress of Endocrinology. In a cohort of women ...

In this article, the focus is on cardiac rhythm and conduction abnormalities of the heart, which all have unique presenting characteristics. These characteristics include ectopic beats, tachycardias ...

Note the gradual onset of the junctional mechanism as the sinus cycle length increases from 635-670 milliseconds while the ectopic rhythm usurps the sinus rhythm at a more rapid cycle length of ...

Background A routine sports evaluation identified constant alternation between a junctional and idioventricular rhythm in a 9-year-old child. During exercise testing, electrography demonstrated ...

Incomplete erasure of tape. Two independent ventricular rhythms are identified: a larger QRS, labeled R, whose P wave and T wave are also labeled, and a smaller QRS, considered "ectopic" and ...

The last of three articles on using an electrocardiogram to assess the heart’s electrical activity focuses on causes of cardiac rhythm and conduction abnormalities and how to spot them This is the ...
