Isoelectric segments of ECG
All the signal is one continuous flow, so all isoelectric segments between the global QRS onset and the global QRS offset should
be captured, recorded, and displayed. This also includes the duration measurements of the respective adjacent waveform.
Heart Rate calculation method
Heart rate is calculated by converting the time between consecutive beats (obtained from the measuring the R-R interval)
and converting this value to beats per minute.
Measurement Ranges
Heart Rate 1 - 240 bpm
Respiration
0 to 60 breaths/min (1 breaths/min) as derivation from
ECG, calculated in frequency.
ST segments detection
•
ST Segments analysis is performed on the one Lead.
•
A slope qualifier is implemented if the value is less than 90 degrees.
•
The ST Analysis has a minimum duration of 60 seconds, designed with the option of increasing it or decreasing it to a
maximum of 30 seconds.
•
Detection of both elevation (range: 1 to 4 mm, default: 2 mm) and depression (range: 0 to -3 mm, default: -1 mm) is
implemented.
•
The heart rate is always being reported, even in the case of an ST Segment being detected
