%X The purpose of the case report is the analysis of the effects of rhythm changes on ejection fraction (EF) of the left ventricle (LV), which can be determined by transthoracal echocardiography. For this purpose, we have analyzed five patients with different rhythm changes. From three of them the conversion was spontaneous, one patient was converted with DC shock of ICD, and the other patient was converted medicamentosly.While analyzing the hemodynamic changes of the heart rhythm, one can see the need and the urgency for converting some of these changes ¡ª based on the effects that rhythm changes have in the hemodynamic function of the heart. According to the data, some of hemodynamic changes of the LV are almost minimal, like in the paroxysmal supraventicular tachycardia (PSVT), while the changes are enhanced in the atrial fibrillation (AF) with an uncontrolled ventricular rhythm, and especially in the ventricular tachycardia (VT). This indicates the need for a fast conversion of the rhythm in VT and with a DC shock when required. Also in the cases of AF, in cases of inability of conversion of the rhythm in a sinus rhythm, control of the heart rate gives an important hemodynamic effect that can be seen from echocardiographic parameters
