[State of the atrial myocardium in patients with paroxysmal form of fibrillation arrhythmia].

Seven two patients with coronary heart disease complicated with paroxysmal atrial fibrillation were studied by using accelerated atrial vector cardiography and M-mode echocardiography. Vector cardiography made it possible to reveal the signs of left atrial hyperfunction with normal left atrial echocardiographic dimensions. There were lower values for left ventricular myocardial contractility in parallel with higher echocardiographic dimensions of the left atrium.

[Significance of echo- and vectorcardiographic studies of the heart atrium in the assessment of intracardiac hemodynamics and myocardial contractility].

Seventy three patients with coronary heart disease (CHD) complicated by paroxysmal atrial fibrillation (PAF) were examined. Vectorcardiography developed by I. A.

[The pharmacodynamics and pharmacokinetics of bonnecor in patients with different disorders of the heart rhythm].

The clinical pharmacokinetics and the effect of bonnecor on parameters of the pharmacodynamics were studied in 53 patients with cardiac rhythm disorders, including 23 patients in the acute period of myocardial infarction. At intravenous administration of bonnecor in a dose of 0.4-0.

[Use of ethacizine tablets in paroxysms of atrial flutter and fibrillation].

Tablets of ethacizine (a phenothiazine series agent) were used for relieving paroxysms of atrial fibrillation and flutter in 30 patients during 103 attacks. The agent produced a favourable effect in 15 patients in 80 paroxysms of atrial fibrillation. The mean time of sinus rhythm recovery was 1.
