E.1. Heart Rate Feedback from ECG
When an ECG device is connected to the ergometer it is advantageous to supply the
ergometer with a feedback of the recorded heart rate. This allows the heart rate to be
continuously monitored as an alarm parameter. When performing pulse-steady-state
training a continuous heart rate input is indeed absolutely necessary. If the ECG device
used supports a QRS trigger output, this can be connected to the ergometer. There are
two possible connections (see appendix C), either the analog interface (J13, Pin 7) or over
the opto-input (J11, Pin 2).
E.2. Pulse Monitor
Ergoline offers a pulse monitor, type Polar, that can be used for heart rate input to the ergom-
eter without an ECG. The receiver of the pulse monitor is connected to the opto-input of the
ergometer. The QRS impulse is then radio transmitted from the chest strap to the ergometer.
