摘要：An electrocardiographic measurement system, method and device uses a devicesuch as an inclinometer, which measures the body position in three orthogonal planes x, yand z in order to correct the calculated vector for changes in ECG parameters, especiallyS-T segment level during ischemic attacks. Recordings are made with a sixteen channelrecorder for twenty four hours and so it is necessary to have a measure of the posture ofthe 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 threeplanes x, y and z. By initial calibration of the ECG changes due to body position orcontinuous running average the calculated vector of the ECG can be corrected bystandard geometric methods.
