The temperature of saline as it enters the vessel, the temperature of blood and saline mixed in the distal part of the vessel, and the distal coronary pressure were measured by a pressure\/temperature sensor-tipped guidewire. The feasibility and safety of the method were tested in 135 patients who were referred for coronary angiography. No significant adverse events were observed; in 11 (8.1%) patients, bradycardia and concomitant atrioventricular block appeared transiently and were reversed immediately on interruption of the infusion. The reproducibility of measurements was tested in a subgroup of 80 patients (129 arteries). Duplicate measurements had a strong correlation both for coronary blood flow (\u03c1=0.841,\n              <jats:italic>P<\/jats:italic>\n              &lt;0.001; intraclass correlation coefficient=0.89,\n              <jats:italic>P<\/jats:italic>\n              &lt;0.001) and R (\u03c1=0.780,\n              <jats:italic>P<\/jats:italic>\n              &lt;0.001; intraclass correlation coefficient=0.89,\n              <jats:italic>P<\/jats:italic>\n              &lt;0.001).
