Hans Strandberg: Body activity controlled heart pacer. Siemens Aktiengesellschaft, Hill Van Santen Steadman & Simpson, December 12, 1989: US04886064 (131 worldwide citation)

Body activity sensors, such as termperature, motion, respiration and/or blood oxygen sensors, are positioned in a patient's body outside the pacer capsule. These sensors wirelessly transmit body activity signals, which are processed by circuitry in the heart pacer, such that a stimulation pulse gene ...

Anders Lekholm: Body activity controlled heart pacer. Siemens Aktiengesellschaft, Hill Van Santen Steadman & Simpson, April 4, 1989: US04817606 (8 worldwide citation)

A body activity sensor in a rate adaptive pacer responds to myoelectrical signals in the patient's electrocardiogram (ECG). These myoelectrical signals are a measure of body activity and thus control the pulse generation rate of the pacer. Preferably, the myoelectrical signals are obtained by filter ...

Strandberg Hans: Body activity controlled heart pacer.. Siemens Elema, Siemens, May 31, 1989: EP0317986-A1 (6 worldwide citation)

Body activity sensors (6,7), such as temperature, motion, respiration and/or blood oxygen sensors, are positioned in a patient's body outside the pacer capsule (1). These sensors (6, 7) wirelessly transmit body activity signals, which are processed by circuitry (9, 10, 11)in the heart pacer (1), suc ...
