Abstract

A method for presenting the heart rate of intact animals as a kymographic record is described. A transistorized impulse generator with a dry battery power supply is used to produce pulses. The pulses are integrated and make a pen motor drived. The ability of the instrument to follow a wide range of heart rate change is demonstrated. The instrument is especially usefull to observe an acute and transitory heart rate change. A method for changing the heart beat to sound and a method for counting the heart rate of intact animal and isolated preparations by employing post office counter were also described.
