Monitoring device and method for operating a monitoring device

A monitoring device for a patient for predicting a cardiovascular anomaly, the monitoring device comprising:

• a first input;
• a sensor connectable to the first input and configured to acquire a value of a physiological parameter based on a cardiovascular anomaly, the first input and the sensor being implantable;
• a second input;
• a detection unit connectable to the second input and configured to detect a value change of a state parameter that is different from the physiological parameter, the state parameter being a different physiological parameter or a parameter characterizing a state of a medical device connected to the patient or a parameter characterizing another physical or pharmacotherapeutic state of the patient;
• an analysis unit operationally linked to the implantable sensor and the detection unit, the analysis unit configured to, upon a detection of the value change of the state parameter, determine a value change of the physiological parameter occurring upon the value change of the state parameter and configured to provide a first differential signal as a function of the determined value change of the physiological parameter;
• a transformation unit configured to receive the first differential signal and to transform it into a characteristic variable as a function of a chronological correlation of the value changes of the state parameter and the physiological parameter and/or as a function of an absolute value and/or a direction of the detected value change of the state parameter and to provide it;
• and
• a prediction unit configured to receive and evaluate the characteristic variable and to provide an evaluation result signal indicative of an imminence of a cardiovascular anomaly as a function of the evaluation,
• wherein the analysis unit is configured to ascertain a time duration between the beginning of the value change of the state parameter and the end of the value change of the physiological parameter and wherein the transformation unit is configured to relate the first differential signal to the ascertained time duration and to provide the time-related first differential signal as the characteristic variable.
