11 Recording an event
The device records events either when the patient presses the
pushbutton, automatically when settable limit values are ex-
ceeded or specified target values are not reached, or at settable
time intervals.
You can set the
pre- and post-event times
as explained in the
“The “Setup” window” section on page 43.
11.1 Manual recording by pressing the
pushbutton
Manual recording is always available even if automatic recording
is activated.
The patient must press the appropriate pushbutton to start man-
ual recording either whenever any symptoms occur or at regular
intervals specified by the doctor.
An acoustic signal (beep) sounds to indicate that the recording
was started.
11.2 Automatic recording
Automatic recording is always started either when the recorder
has detected an event or at specified time intervals.
11.2.1 Automatic detection of arrhythmias
The recorder uses built-in algorithms for automatic detection of
certain arrhythmias (bradycardia, tachycardia, atrial fibrillation,
pause).
These algorithms are based on the continuous detection of the R
waves and the calculated heart rate values. The automatic ar-
rhythmia detection is automatically turned off if the ECG signal is
noisy or very weak.
You may specify the limit values and other parameters for auto-
matic arrhythmia detection by way of the software CM 100 Con-
figurator.
