A dynamics and origin of changes in the end part of spontaneous ventricular complexes has been studied in 109 patients with permanent ventricular pacing. Pacemaker inhibition test and potassium test have been shown to increase the detection rate of true functional Chaterier syndrome characterized by ST depression and T wave inversion in spontaneous QRS complexes in leads II, III, aVF and V2-V6 , from 39. 9 % to 72. 6 % cases. This allows to rule out non-Q wave myocardial infarction
