ECG measurements in watery environments.

(a) The ECG electrode remains robustly attached to the chest even when the electrode is submerged in bath water. The ECG acquisition module was affixed to the left arm with an elastic band and a Bluetooth communication system transmitted the ECG signal to a (b) distant notebook wirelessly. (c) The ECG waveform recorded during the bath. An EMG signal (arrows) arose intermittently when the subject changed his body posture.
