title: Digital heart rate monitor derived from the arterial pressure pulse.
abstract: This monitor displays heart rate without the need for electrical contact with the experimental animal. The device uses a quartz pressure transducer connected to an arterial catheter and has a full scale accuracy of +/- 3 beats min-1; its range is 0-400 beats min-1. There is an output voltage proportional to heart rate and internal calibration facilities are provided at 60 and 360 beats min-1.
