Webb7 nov. 2024 · A 12-lead ECG obtained on admission (Figure 1) shows bradycardia with a slow ventricular rate of 50 beats/min. The P waves are inverted in leads II, III, aVF, and V4–V6 and upright in lead aVR, suggesting an ectopic atrial rhythm. The QRS duration is 90 ms, and the QT and QT c intervals are 402 and 391 ms, respectively.

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. WebbThere are five main parts of the electrocardiogram or EKG. The P wave is a small wave which represents atrial depolarization. The T wave represents ventricular repolarization which is obscure by the QRS complex. The PR interval measures time between the initial P wave and the initial deflection of the QRS complex.
