Device for recording the heart rhythm has electrodes and converter, so that the heart trace can be converted to an audible signal that can be used to detect irregularities in the heart in an easier way than visually

摘要

Device for monitoring the heart has electrodes connected to the skin with the measured potential difference amplified and then converted (3) into a sound signal that gives a distinctive melody for the sound of the heart rhythm. A certain melody is recorded for normal operation and is standardized so that abnormal behavior can be recognized. Adjusters (4,5) can be used to change volume and time interval between audible signals.
