Cardiac Complication Following Subarachnoid Hemorrhage
Besides its severe neurological injuries, spontaneous subarachnoid hemorrhage (SAH) commonly causes cardiac complications. These complications could include three different aspects of cardiac diseases, that is, electrocardiographic abnormalities, myocardial injuries, and left ventricular dysfunction. These complications not only may lead to misdiagnosis of SAH as myocardial infarction, but also...
متن کاملAutonomic influences on cardiac function in the newborn lamb.
The influences of reflexly induced changes of sympathetic outflow to the heart on left ventricle contractility, heart rate, and systemic vascular resistance were studied in 26 technically successful experiments with newborn lambs ranging in age from 1 to 11 days. Reduction of brachiocephalic artery perfusion pressure was associated with a large increase of heart rate and of systemic vascular re...
متن کاملInfluences of hypercapnia on cardiac function in the newborn lamb.
There is an abundance of evidence which suggests that hypercapnia impairs the performance of isolated heart-lung preparations, and that this is primarily consequent to diminished contractility of the myocardium.'7 Patterson' showed that the cardiac depressant effect of CO2 could be prevented largely by the addition of epinephrine. In intact adult dogs acidosis produced by CO2 retention causes s...
متن کاملCoronary flow and myocardial oxygen metabolism in the newborn lamb.
Analysis of factors which may influence oxygen metabolism of the heart has received much attention since the early part of this century (1). Quantitative measurements of coronary blood flow and myocardial oxygen consumption (MVO,) have been accumulated from both human and animal studies (2, 3). These studies were uniformily concerned with adults, however, and virtually no information is availab...
متن کاملEstrus cycle: influence on cardiac function following trauma-hemorrhage.
Since cardiac function is depressed in males but not in proestrus (PE) females following trauma-hemorrhage (T-H), we examined whether different estrus cycles influence cardiac function in female rats under those conditions. We hypothesized that females in the PE cycle only will have normal cardiac function following T-H and resuscitation. Sham operation or T-H was performed in five groups of ra...
