“…Several methods have been used in the past to provide a quantitatiye means of measuring coronary blood flow in man, including indicator-dilution and radioisotope techniques as well as Doppler ultrasonic flow catheter measurements and densitometric evaluations of coronary angiograms. [1][2][3][4][5][6][7][8] Generally x-ray densitometry is based on the determination of the mean transit time of contrast medium. Mean transit time is defined as the difference between the mean appearance times of the contrast medium measured from the "densograms" (time function of x-ray density) at a proximal site and a distal site over the vessel.…”

“…Gorlin and Storaasli (1956) firstly measured the transcoronary circulation time in man using the radioactive iodinated serum albumin. Benchimol et al (1971) measured instantaneous coronary artery blood flow rate by means of a catheter-tip ultrasonic flowmeter and investigated the effects of respiration and nitroglycerin on coronary circulation in man. Recently, Liedtke et al (1973) compared myocardial transit times in patients with and without coronary artery disease utilizing rapid injection of dye into the coronary artery and recording dye-dilution curve from the coronary sinus.…”

“…8 The method for obtaining such carotid artery blood flow velocity signals by radiotelemetry has been previously described in detail. 6 The Doppler ultrasonic method of measuring blood flow velocity has been applied to more than 1,000 subjects in the past four years in order to study coronary, 9 renal, 10 superior mesenteric, 11 and aortic blood flow velocity 12 under a variety of clinical and experimental conditions. Right carotid artery flow velocity, lead II of the electrocardiogram, tricuspid area phonocardiograms and at times apexcardiograms, external carotid pulse tracings and right atrial or ventricular pressures were recorded simultaneously.…”
