| 摘要 |
The invention relates to a method of interference-tolerant heartbeat measurement, in which method the heartbeat signal of a person is measured from a suitable part of the body and transmitted as burst signals from a transmitting means (1-4) to a receiver (5-10) by means of telemetric data transmission, the transmitting interval of the burst signals being proportional to the measured heartbeat rate of the person. According to the invention, the burst signal is amplitude-modulated with a frequency or a frequency sequence characteristic of each transmitter/receiver unit, or a phase-shift sequence characteristic of each transmitter/receiver unit is caused in the burst signal at desired intervals, the receiver recognizing bursts intended for it on the basis of this sequence.
