Fortunately … WebAug 18, 2016 · A pseudofusion beat is a QRS complex that is formed by a depolarization of the myocardium initiated by a patient’s intrinsic heartbeat completely; however, a pacemaker spike is present, distorting the QRS complex. These can be normal occurrences in pacemaker patients due to timing of the depolarization wave in the ventricle.
