Capture beats ecg
WebVT, capture beats occur when an occasional, normal sino-atrial node impulse is conducted through to the ventricle. Fusion beats occur when ventricular muscle is depolarized simultaneously by both a normal, supraventricular and abnormal, ventricular beat, which produces a QRS duration length between the two (Fig. 3). What is a capture beat on ECG?
