| Zusammenfassung: | An implantable medical device for detecting physiological events includes a first sensor for sensing a first signal in a patient correlated to a first physiological condition, a second sensor for sensing a second signal in the patient corresponding to a second physiological condition and a third sensor for sensing a third signal in the patient corresponding to a third physiological condition responsive to the second physiological condition. Control circuitry for receiving the first, second and third signals is configured to determine a relationship between the second signal and the third signal, detect a change in the relationship between the second signal and the third signal and determine a threshold in response to detecting the change in the relationship between the second signal and the third signal. A physiological event is detected in response to the first signal crossing the determined threshold. |
