Regulation of Cardiac Output Through Stroke Volume

Regulation of cardiac output through stroke volume.

Pulsed Doppler echocardiographic determination of stroke volume and cardiac output

Two methods of measuring stroke volume and cardiac output with pulsed Doppler twodimensional echocardiography were developed and validated against the thermodilution technique in 39 patients, 33 of which were in an intensive care unit. With the use of the apical four-chamber view, a mitral inflow method combined the velocity of left ventricular inflow at the mitral anulus with the crosssectiona...

Changes in cardiac output and stroke volume during first four months after cardiac infarction.

The circulatory changes that occur within the first four months after cardiac infarction have not been studied to the same extent as those occurring during the acute phase ofthe illness. Measurements of cardiac output and stroke volume have been made in some patients before leaving hospital (Pritchard and Hellerstein, 1950; Gammill et al., 1955; Lee, 1957; Broch et al., 1959; Thomas, Malmcrona,...

Cardiac output and volume in hypertension

Of these three parameters, only blood pressure can be measured precisely and continuously. The two components which determine the height of blood pressure are influenced by numerous factors composing a regulatory system, the complexity of which is only too often neglected in the interpretation of data from studies in which changes of isolated parameters have been measured. The situation becomes...
