Embodiments include a leadless implantable heart stimulator (that includes an acceleration sensor, wherein the acceleration sensor delivers an acceleration signal as an output signal. The acceleration sensor is connected to an activity determination unit. The activity determination unit generates an activity signal from the acceleration signal wherein the activity determination unit at least partially subtracts a component of the acceleration signal from the acceleration signal that represents an intrinsic heart movement.

Rate-adaptive heart stimulator and activity sensor

A device and method that detects a lead failure condition for a lead having at least one electrode in contact with body tissue, wherein the lead is connected to the device. The device includes a first filter that filters an electric signal sensed by the at least one electrode to a first filtered signal, and a lead failure detection unit that detects signal characteristics of the first filtered signal. The lead failure detection unit indicates a lead failure condition when the detected signal characteristics correspond to a step response of the first filter.
