Webb9 sep. 2015 · Telling Signs With EKG. When physicians review EKGs, a few telling signs may indicate that the patient has had a pacemaker implanted. In atrial pacing, a pacemaker spike is followed by a P wave with morphology dependent upon the location of the atrial pacer lead. The QRS complex appears as if in sinus rhythm.

Webb12 apr. 2024 · An increased P wave duration, an increased P wave, a leftward shift of the heart axis, and a low QRS voltage are commonly observed in a subject with a high BMI . Furthermore, obesity is the most significant risk factor for left atrial enlargement [ 41 ], which is significantly related to an increased prevalence of atrial fibrillation and the …
WebbThe P Wave: The P wave of an electrocardiogram (EKG or ECG) represents the depolarization (i.e., contraction) of the atrial muscles. The atria are the top two … WebbBackground: Typical atrial flutter (AFL) is a macroreentrant arrhythmia characterized by a counterclockwise circuit that passes through the cavotricuspid isthmus with passive depolarization of the left atrium.These electrical events are thought to be responsible for the classic “sawtooth” wave of atrial flutter seen on the surface electrocardiogram …
