METHOD AND APPARATUS FOR SENSING AND ANALYZING ELECTRICAL ACTIVITY OF THE HUMAN HEART

摘要

A method of sensing, and analyzing electrical activity of the human heart comprises the sensing of voltage signals generated by the heart between four electrodes (E, A, S and I) located at key positions on the surface of a subject's body. The E electrode is attachable to the anterior midline of the subject body at a level selected from the group consisting of the fourth rib interspace, and the fifth rib interspace. The A, and I electrodes are attachable to the subject's body on opposed sides of the anterior midline below the level of the E electrode but high enough so they are positioned over the subject's ribs or intercostal spaces. The S electrode is positioned over the subject's manubrium sterni. Signal processing means (100) combines, and scales the voltage signals to produce XYZ vectorcardiographic signals, electrocardiographic signals corresponding to the lead signals of a 12-lead electrocardiograph, or both.
