Left-ventricular performance in man during breath-holding and simulated diving
cardiovascular human breath holding
2009/7/20
We measured left-ventricular (LV) systolic time intervals (STI) to determine whether breath-holding and simulated diving evoke a depression of LV performance in man similar to that previously demonstr...
Changes in left ventricular activity during apnea and face immersion
human face immersion left ventricular function apnea cardiac
2009/7/20
Apneic face immersion in water has been analyzed with respect to its effects upon heart rate and ventricular function in a group of highly trained teenaged swimmers of both sexes. Both parameters have...
Absence of antiarrhythmic effects of helium in patients with spontaneous eprematur ventricular beats at rest
human air spontaneous eprematur ventricular beats
2009/7/17
Six patients with spontaneously occurring arrhythmias were studied to assess the antiarrhythmic properties of helium. The patients were divided into two subgroups breathing air, helium-oxygen (heliox)...
Influence of hyperbaric oxygen on left ventricular contractility, total coronary blood flow, and myocardial oxygen consumption in the conscious dog
HBO CO2 carbon dioxide hyperbaric cardiac output air dog animal myocardial contractility
2009/6/12
It is known that hyperbaric oxygenation (HBO) decreases total coronary blood flow (TCBF) and cardiac output (CO). To determine whether this is related to an alteration in myocardial contractility, 10 ...
Effects of hyperbaric oxygen on ventricular performance,pulmonary blood volume,and systemic and pulmonary vascular resistance
pulmonary cardiovascular hyperbaric air
2009/6/8
The cardiovascular effects of hyperbaric (3 atm abs) air, 100% oxygen, and hyperbaric oxygen (HBO2) at 3 atm abs were investigated in 13 pentobarbital-anesthetized dogs. We measured heart rate, arteri...
