title: [Clinico-hemodynamic changes in paroxysmal cardiac arrhythmias].
abstract: The stroke and minute volumes, according to the method of Fick and formula of Staar, were studied with a view to the necessity of objectivization of some hemodynamic indices for the needs of clinical practice. Based on the good results, obtained by the formula of Staar, the stroke volume was calculated according to the same mode in patients with rhythm disorders. The stroke volume was established to reveal a dependence on heart rate, type of rhythm disorder and character of the basic disease. The manifested clinical signs of congestive cardiac insufficiency originate at a certain cardical rate (different in atrial flutter and paroxysmal supraventricular tachycardia), the type of the basic disease being with the highest significance (myocardial state). A viewpoint is presented on the expedience of one universally accessible, non-invasive study on the hemodynamics of patients with paroxysmal disorders of cardiac rhythm.
