Method and a device for monitoring heart function
First Claim
Patent Images
1. A device for monitoring heart function comprising:
- sensor means for monitoring at least one of momentum and velocity of a heart mass, the sensor means being adapted for positioning in correspondence with a region of the heart mass which is exposed to a contractile movement of the heart;
means operably connected to the sensor means for generating a monitoring signal indicative of heart activity; and
means for eliminating from the monitoring signal a component of the signal which is inherent in the contractile movement of the heart mass.
