Left Ventricular Volume in Man Measured by Thermodilution.

Left Ventricular Volume Measurements in Man by Thermodilution.

A safe, rapid method for estimating left ventricular volume in man during the course of hemodynamic studies should prove helpful in the assessment of cardiac disease and useful in physiological research. It is the purpose of this report to present left ventricular volume measurements in man that were obtained by an indicator dilution method which employs cold as the indicator. This circulatory ...

Left ventricular volume in aortic stenosis measured by an angiocardiographic and a thermodilution method.

The action of the left ventricle is impaired in aortic stenosis to a variable degree, and since the extent of myocardial damage will influence the management and prognosis in the individual patient, some way of determining myocardial function is required. For a full assessment of left ventricular performance it is necessary to measure the changes in both volume and pressure throughout the cardi...

Left ventricular volume changes after amyl nitrite and nitroglycerin in man as measured by ultrasound.

SUMMARY The therapeutic effect of nitrites in myocardial ischemia is considered to be due in part to a reduction of left ventricular volume but measurement of this parameter in man has been difficult. The technique of echocardiography was used to measure changes in left ventricular end-diastolic volume (LVEDV) and end-systolic volume (LVESV) after administration of amyl ni

Changes in left ventricular stroke volume measured by Doppler echocardiography.

Cardiac stroke volume was measured simultaneously by Doppler echocardiography and thermodilution in 20 patients with coronary artery disease. Stroke volume as determined by ultrasound was calculated from the area of the aortic orifice and the flow velocity just distal to the aortic cusps. The recordings were made twice at rest. Ten patients were given dobutamine (2.5 and 5.0 micrograms/kg/min) ...
