Abstract

The authors studied the isoenzymatic spectrum of lactic dehydrogenase of the myocardium, the frequency of cardiac contractions and ECG during the action of high carbon dioxide concentration, and also the survival of rats depending on the speed of carbon dioxide concentration increase in the atmosphere. Functional changes noted in the cardiac activity during the carbon dioxide action (concentration 30%, 7 1/2 hours) were not accompanied by any disturbances of carbohydrate metabolism in the myocardium. The most important condition for the survival of rats subjected to the action of high carbon dioxide concentration (up to 50% in the atmosphere) was the speed of elevation of this concentration.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
