Fibrillation thresholds and their relationship to the duration of 60 Hz current flow, expressed as the number of 60 Hz cycles applied to the heart are described. Results are obtained for catheter surface areas ranging from 0.224 mm2 to 90 mm2. The in

The effect of 1.0 MHz ultrasound at an intensity of 1.0 W/cm2 SATA on brain function of anaesthetized cats was assessed using Visual Evoked Potentials (VEPs). Ultrasound alone did not significantly modify the averaged VEP signals. However, acute hypo

Cardiac stimulation thresholds of short-duration large-amplitude electrical transients were studied. An isolated rabbit heart model was used and transients were applied directly to the heart through electrodes of 1 mm2 and 1 cm2 surface area. A varie

A single-shot procedure for coronary arteriography has provided effective visualization in dogs. An electronic circuit controls injection of a small bolus of contrast medium over two or three heart cycles by the retrograde approach, and automatically

A new method for the continuous measurement and recording of sweat rate has been developed. The sweat rate is determined by continuously measuring the change in resistance of a sensing element which, in turn, reflects the change in moisture content o
