E30 Digital Electrocardiograph User’s Manual
5-6
If missing of check of R wave is caused by some lead fall-off and QRS
low voltage, the measurement of HR will possibly have big error.
In case of QRS low voltage, the calculation of ECG axis and the
dividing point identification of QRS wave are unreliable sometimes.
Frequent ventricular extrasystole is occasionally regarded as
representative heart beat through checkup.
Identification of P wave is difficult in case of combined arrhythmia,
and the relevant parameters are possibly unreliable.
The Electrocardiograph has the function of automatic analysis. It only
conducts automatic ECG analysis of the ECG waveform acquired,
instead of reflecting all the status of the patient. The analysis result is
sometimes different from diagnosis of doctor, so the final conclusion
shall be made by doctor after comprehensive diagnosis and analysis
based on analysis result, clinical symptoms and other test results of
the patient.
