Atrial fibrillation can be interpreted by noting.

But in atrial fibrillation, the signals in the upper chambers of the heart are chaotic. As a result, the upper chambers tremble or shake. The AV node is flooded with signals trying to get through to the lower heart chambers. This causes a fast and irregular heart rhythm.

Atrial fibrillation can be interpreted by noting. Things To Know About Atrial fibrillation can be interpreted by noting.

Atrial fibrillation (AF) describes the rapid, irregular beating of the left atrium or upper chamber of the heart. These fast contractions of the heart are weaker than normal contractions. This results in slow flow of blood in the atrium. The blood pools and becomes sluggish and can lead to the forming of blood clots.The cardinal manifestation of pacing on surface ECG is the stimulation artifact (Figure 1). In atrial pacing, the stimulation artifact precedes the P-wave. In ventricular pacing, the stimulation artifact precedes the QRS complex. Two artifacts are seen if both chambers are paced. The stimulation artifact is larger in unipolar pacing, as ...Introduction. Atrial fibrillation (AF) is the most common arrhythmia among adults, and its clinical implications are significant. AF is associated with an increased risk for thromboembolic events, specifically cardioembolic ischemic stroke, as well as elevated risk for heart failure and all-cause mortality 1-5.Given its profound public health burden, AF diagnosis and management have been the ...Atrial fibrillation (AF) can manifest in a broad range of acute medical and surgical conditions.
