Aportable electrocardiograph device is being used by the US Public Health Service in Alexandria, Va, to take an automated communitywide cardiac survey.
The Alexandria Health Department and the PHS Heart Disease Control Program collaborated with Honeywell, Inc., in the development of a 7 lb, battery-operated electrocardiograph machine and a magnetic tape system for recording the electrocardiograms (ECG's) at a receiving station in Washington, DC.
The ECG's are taken in the patient's home by Public Health nurses who transmit the data by special telephone hook-up to the magnetic tape system. After the electrodes have been positioned, the nurse dials a telephone number at the receiving station at George Washington University which is self-answering and which automatically starts the tape recorder. Then the telephone mouthpiece is inserted into a Bell System Dataphone which transmits high frequency signals to a similar set at the field station. The portable ECG machine produces the standard,
