Abstract:
A method for self-diagnosis of acute myocardial infarction at the moment of chest pain indicating ischemic activity for an early diagnosis, in the first four to six hours of said acute myocardial infarction to determine with a high degree of effectiveness when an artery of the heart is acutely obstructed by trombus or rupture of atherosclerotic plaque related to said ischemic activity by means of a device attached with a negative wire to the patient's right armpit, a positive/negative wire attached to the patient's left armpit and a positive wire attached to the lower part of the patient's abdomen including the hipogastrium, and further including positive and negative electrodes placed in a V4 position at the 6th to 8th intercostal space along the midclavicular line, where the said electrodes may be placed against the skin of the patient without any gel or conductive substance, wherein said device further includes an analog to digital converter and a microcontroller, the method comprising;a) sensing a shift of st segment below or above a baseline, wherein a green light alarm is generated by said device if said shift is between 0-1 millimeters, or 0-100 microvolts, in absolute value and a yellow light alarm is generated by said device if said shift is between 1-2 millimeters, or 100-200 microvolts, in absolute value and a red light alarm is generated by said device if said shift is greater than 2 millimeters, or greater than 200 microvolts, in absolute value wherein said green alarm indicates low risk, said yellow alarm indicates medium risk, and said red alarm indicates high risk for said acute myocardial infarction of the subendocardial type; b) wherein said analog to digital converter digitizes the patient's ECG signal and inputs said digitized ECG signal into said microcontroller in real time, wherein said microcontroller processes said signal and senses said shift of st segment and further triggers said alarms.
