Abstract: The present invention discloses a hand based blood pressure measurement system, apparatus and method. In one embodiment two or more hand-based electrocardiogram (E.C.G.) sensor and one or more hand-based arterial pulse wave measurement sensor are used. These respectively determine the E.C.G. waveform associated with the heart beat blood transmission pulse and the GO arterial pulse/wave measurement. This data is used to measure the pulse transit time for one or more heart beats. In one embodiment the arterial pulse measurement is done using a photoplethysmogram sensor. In another embodiment the arterial pulse measurement is done using a pressure sensor.
