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. WebbOn an ECG, atrial flutter resembles F waves with a sawtooth pattern. This is the result of an ectopic atrial pacemaker or because of a rapid reentry pathway somewhere within the atria but outside of the SA node area. …
