title: [Effect of hyperoxia and increased environmental gas density on the contractile function of the right of the heart].
abstract: Rheocardiography, phonocardiography, and electrocardiography were used to investigate right ventricle function of 16 test subjects exposed to various gas atmospheres under increased pressure. During short-term exposures the adverse effect of an increased pressure on the contractile function of the right ventricle grew in the following order: hyperoxia--normoxic nitrogen-oxygen atmosphere--compressed air.
