The correct diagnosis is sinus rhythm and atrial bigeminy (Figure 2). The rhythm appears to be regular; however, there is slight irregularity, ie, the RR intervals are 0.40 sec (⨅) alternating ...

A P wave (↓) occurs prematurely after each sinus beat (atrial bigeminy). These P waves occur at a time when the AV conduction system is refractory, and they are blocked (nonconducted atrial ...

The third and fourth complexes of this ECG show sinus bradycardia at about 50 beats per minute. The remainder of the tracing shows atrial bigeminy with a coupled aberrant atrial premature beat ...

One (A.H.) of the 3 had had ventricular bigeminy in the past, and after 0.3 mg. had been given, ... Atrial premature beats were not produced by acetylstrophanthidin.

The ECG findings include: 1. Normal sinus rhythm. 2. Premature atrial contractions in a pattern of atrial bigeminy. In atrial bigeminy every second beat is a PAC resulting in an regularly ...

Dr. Roach: Several months ago, I developed a case of a bigeminy heartbeat. My cardiologist prescribed metoprolol. At about the same time, I had reduced my intake of magnesium from ...

The situation in which atrial fibrillation can cause permanent heart damage is if a patient develop atrial fibrillation and the heart rate ends up being very very rapid for a long period of time.

In contrast, during atrial fibrillation, the atria are being activated at rates in excess of 400 beats per minute in a chaotic electrical pattern,” says Richard L. Page, MD, chair in the ...

The regular arrhythmia occurring at the beginning of the electrocardiogram was identified as ventricular bigeminy. Single ventricular premature complexes (VPCs), as well as pairs and triplets of ...
