[Optimal methods of the physical rehabilitation of patients with chronic ischemic heart disease with rhythm disorders]. / Optimizatsiia sredstv fizicheskoi reabilitatsii u bol'nykh khronicheskoi ishemicheskoi bolezn'iu serdtsa s narusheniiami ritma.

A study of 186 coronary patients with rhythm disturbance has shown that early incorporation of the elements of physical rehabilitation in combined treatment improves functioning of all the links of the blood circulation system, helps to raise cardiac rhythm stability and reduces the period of patients' stay in hospital.

[Prevention of ventricular fibrillation with the aid of protopine in animal experiments]. / Profilaktika fibrilliatsii zheludochkov serdtsa s pomoshch'iu protopina v eskperimente.

The anti-arrhythmic activity of protopin, quinidine and novocainamide infused intravenously as a preventive and relieving measure was studied in acute experiments on rats with calcium chloride and aconitic arrhythmia. In myocardial fibrillation induced by calcium chloride the contents in the rat heart of adrenalin, noradrenaline, dopa and dopamine were studied by spectrofluorimetry before and after the use of protopin. It was established that in the size of its minimum effective doses which arrest or prevent calcium chloride and aconitic arrhythmias in rats protopin is two to three times more potent than quinidine and novocainamide. The mechanism of the anti-arrhythmic effect of protopin in calcium chloride and aconitic arrhythmias is complex and is due to the suppression of the foci of heterotopic stimulation, decrease in excitability of the myocardial cells and normalization of the catecholamine content in the myocardium.
