    Abstract:
    Considers the design of a computer system for measuring cardiac electrical signals while simultaneously controlling heart rate and rhythm. The system is used for investigations ranging from ECG measurements from patients to the electrical study of isolated strands of animal hearts in a tissue bath. The system comprises five basic tasks: (1) synchronizing the system with events occurring in the heart (cueing); (2) recording heart signals in digital form and immediately displaying their wave forms; (3) controlling heart rate and rhythm by appropriately timed stimuli; (4) continuously displaying the status of the computer and the experiment; and (5) receiving, checking, and executing commands from the investigator. The system's hardware is controlled by a single dedicated laboratory computer
