Method and apparatus for trend detection in an electrocardiogram monitoring signal
First Claim
1. A trend detection method for detecting trends in an electrocardiogram monitoring signal of a patient, comprising:
- extracting locations of base points from said electrocardiogram monitoring signal;
for each said location of base points, the location of the base point is compared against a predetermined threshold range based on a slow adaptative learning process using said patient'"'"'s own cardiac movement, said range having an upper and lower threshold value for both an horizontal and vertical adjusted value for each of said base points;
if all locations are within the predetermined, threshold range, performing a proximity analysis to determine improbable locations;
if all locations are possible, determining an occurrence of a trend in said electrocardiogram monitoring signal from said locations.

Abstract
The present invention can be used in conjunction with a wearable digital wireless ECG monitoring system. A full ECG curve is received by a central module. The central module is worn on the belt like a cellular or a pager. It is made of four different devices operating together: a handheld computer, a GPS, a cellular board and a multiplexing device. The system wirelessly receives the complete cardiac curve from the ECG and is able to distinguish not only the beat rate, but also to analyze any abnormal heart contractions. In fact, most common heart diseases are not related to the acceleration or deceleration of the heart rate. In case of problem detected by the central unit, the system automatically calls a central station and can send the GPS positioning and ECG monitoring of the patient with the detected anomaly data. Voice communication with the patient or the passers by is also possible.
