Webb14 apr. 2024 · In case of sinus bradycardia, the sequence of events on the surface ECG is atrial pacing spike →, paced P wave → preset, atrioventricular delay →, ventricular pacing spike →, and paced QRS. Atrioventricular synchrony is maintained. There is also an upper limit for atrial sensing to avoid fast ventricular rate during atrial fibrillation. Webb22 dec. 2024 · The P wave of the ECG represents atrial depolarization, which is followed by contraction and an increase in pressure in the atria (atrial systole). The AV valves are open, and there is no valve between the atria and veins, so this small increase in pressure is also evident in the ventricle (a wave) and in the veins.
