A wristwatch worn by a user for measuring a three-lead ECG includes three electrodes placed separately on the front, either side, and back or strap thereof. The wristwatch further includes an electrode panel having the electrode on the front or either side of the watch, sensing elements, pressure, infrared or impedance detectors, and circuits. The electrode panel is capable of sensing the contact or press of fingers to trigger the ECG measuring. While the electrode in the back-side of the watch contacts the hand wearing the watch, the electrode and electrode panel on the front or either side of the watch are pressed by fingers from the other hand, and the electrode in the strap contacts the abdomen or left leg simultaneously. Thus, a three-lead ECG can be measured. ECG data can be transmitted to a personal or hospital computer by wireless networks or flash memory.

What is claimed is: 1. A wristwatch for measuring a three-lead ECG, comprising:a case including a front side and a back side opposite to the front side;a strap attached to both ends of the case and including an inside surface and an outside surface, with the inside surface being intermediate the back side and the outside surface;a circuit board disposed in the case;a first electrode positioned on the outside surface of the strap;a second electrode positioned on the front side of the case;a third electrode positioned on the back side of the case, with the first, second and third electrodes being electrically separate for detecting voltage differences generated by cardiac systems, with the circuit board detecting voltage differences generated by the first and second electrodes, by the first and third electrodes, and by the second and third electrodes to obtain a set of ECG data comprising ECG lead I, ECG lead II, and ECG lead III;a display disposed on the case;a control panel comprising one of the electrodes and a plurality of sensing elements; andat least one control button for inputting information, changing function, and modifying user's mode of the wristwatch.
