ABSTRACT:
An electrocardiographic measurement system, method and device uses a device such as an inclinometer, which measures the body position in three orthogonal planes x, y and z in order to correct the calculated vector for changes in ECG parameters, especially S-T segment level during ischemic attacks. Recordings are made with a sixteen channel recorder for twenty four hours and so it is necessary to have a measure of the posture of the subject to interpret the ECG. An inclinometer, which measures gravitational acceleration in all planes to the nearest degree is used, giving three traces for the three planes x, y and z. By initial calibration of the ECG changes due to body position or continuous running average the calculated vector of the ECG can be corrected by standard geometric methods.
