摘要：
A wrist worn device heart monitoring device is presented. The wrist worn heart monitoring device includes a radial tonometer configured to output a pressure signal indicating a pulse pressure wave at a user s wrist two or more electrodes configured to output an electrical signal indicating a user s heart has been commanded to contract and a microphone configured to output an audio signal indicating a closing of a user s aortic valve. The wrist worn heart monitoring device further includes a pulse transit time monitor configured to calculate a pre ejection period of the user s heart based on at least the pressure electrical and audio signals and calculate a pulse transit time based on at least the pre ejection period the pressure signal and the electrical signal.
