    摘要: The present invention discloses an apparatus for non-invasive heart monitoring comprising a pulse wave transit time (PWTT) determining device for determining a PWTT at predefined intervals, a first storing means for storing PWTT values resulting of the determining, a blood pressure measuring device for measuring a blood pressure close in time with the determining and a second storing means for storing blood pressure values resulting of the measuring. Furthermore, the apparatus comprises a cardiovascular dynamic change calculating device for calculating a relative change of the PWTT values and the blood pressure values as a function of time. The apparatus further comprises an alarm emitting device for emitting an alarm if the blood pressure values are substantially constant as a function of time and the PWTT values decrease as a function of time. A method for non-invasive heart monitoring is also disclosed.
