The arterial and intracardiac blood pressures of the left and right hearts were measured to analyze several cardiac parameters in twelve adult beagle dogs. An experiment was performed under anesthesia of fluothane. Catheters were inserted into the left and right hearts through the common carotid artery and jugular vein under fluoroscopy. Each pressure wave was recorded on a visigraph and a data-recorder with a strain gauge pressure transducer. Values of cardiac parameters were analyzed with a signal processor.<BR>In the left heart, each pressure was measured systolic aortic pressure (Ps), diastolic aortic pressure (P<SUB>D</SUB>), mean aortic pressure (P<SUB>M</SUB>), left ventricular end-diastolic pressure (LVEDP), left ventricular peak-systolic pressure (LVP<SUB>KS</SUB>), left ventricular maximum dp/dt (LV max. dp/dt) and time to left ventricular maximum dp/dt (t-LV max. dp/dt).<BR>In the right heart, each pressure was measured systolic pulmonary arterial pressure (PA<SUB>S</SUB>), diastolic pulmonary arterial pressure (PA<SUB>D</SUB>), mean pulmonary arterial pressure (PAM), right ventricular end-diastolic pressure (RVEDP), right ventricular maximum dp/dt (RV max. dp/dt) and right atrial pressure (RAP).<BR>The results are as follows;<BR>1) In the left heart, Ps was 111.0mmHg, P<SUB>D</SUB>, 76.5mmHg, P<SUB>M</SUB>, 87.7mmHg. LVEDP, LVP<SUB>KS</SUB>, LV max. dp/dt, and t-LV max. dp/dt was 9.5mmHg, 113.5mmHg, 2608mmHg/sec and 64 msec, respectively.<BR>2) In the right heart, PA<SUB>S</SUB> was 24.6mmHg, PA<SUB>D</SUB>, 10.2 mmHg, and PA<SUB>M</SUB>, 14.7mmHg. RVEDP, RVPpks, and RV max. dp/dt was 5.0mmHg, 30.5mmHg and 552mmHg/sec, respectively. RAP was 4.1mmHg.<BR>3) There were no significant differences in the value of any cardiac parameter between adult beagles and mongrel dogs.
