WebI don’t think the large downward wave is a qrs, if that’s what you are thinking. What I see is a rS wave, so going left to right following the isoelectric line is a negative p wave, followed by no q wave, then the r wave (the small positive wave). The S wave is the large downward wave and then finally the t wave. Probably looking at lead V1. Web9 de set. de 2015 · From this we know the patient has a dual chamber system because 1 lead must be in the atrium to sense the intrinsic activity and another in the ventricle to pace, most likely programmed DDD. However, the third P wave has no pacing spike or QRS following. Here oversensing must be considered in the differential.
