A multi-function health monitor is capable of performing a resting 12-lead ECG test, an ECG stress test, a 24-hour holter monitor evaluation and or a 30-day MCT monitoring. Using only 3 electrodes, the multifunction health monitor derives 6 channels (Limb leads & Augmented leads) of data with the noise cancellation (ground) effect of a virtual dynamic RL electrode. An electrode resistivity measurement system quantifies and may compensate for increasing resistance the electrodes and the patient that results from the length of time the electrodes are installed on a patient. The multi-function health monitor can provide data analysis through the gate array as the data is acquired. Data may also be stored for remote analysis as well as for transmission to remote stations upon occurrence of one or more threshold events. Parameters for threshold events may be adjusted remotely to obviate the need for a patient to travel for system adjustment.

Electrocardiogram system for synthesizing leads and providing accuracy measure
An electrocardiogram (ECG) system includes a database containing many entries. Each entry contains data used to synthesize a 12-lead ECG from the received ECG lead signals and a measure of the accuracy of the synthesized 12-lead ECG signal. The received ECG lead signal is missing one or more leads due to loosening of the corresponding electrode, or because it is not available at that location on the patient. The synthesized 12-lead ECG can synthesize the missing leads. Additionally, the received 12-lead ECG may also be derived from a patient in a different position than the reference position. The synthesized 12-lead ECG converts the ECG into a 12-lead ECG for the patient in the baseline position. In addition, the synthesized lead signal can be compared with the received lead signal to detect abnormal signals.
