Appendix II
Heart rate calculation method: The non-interference heart rate in the ECG picture segment is N,
and the heart rate (HR) calculation formula is as follows
HR = 60000 / Sum of R-R interval of N heartbeats / N)
Arrest recognition method: According to the pause maximum heart rate or minimum RR interval
set by the user in the "parameter definition" function, compare the RR intervals of
non-interference heartbeats, and the eligible heartbeats are classified as long Pause intermittently.
Supplementary explanation of ST segment analysis;
This software can analyze the elevation or depression of the ST-segment average voltage (ie
ST-segment displacement) for all leads.
The user can calibrate the ST segment of the ECG waveform in the "Arrhythmia Analysis"
function, and in the "Sequence Review" function
Click the "STE" button to set the judgment standard for ST-segment elevation in each lead, or
click the "STD" button to set the judgment standard for ST-segment depression in each lead, that
is, to change the judgment standard for ST-segment elevation or depression in each lead. voltage
range.
The user can view the number of ST-segment elevation and depression in each lead in the
