measurement and interpretations:
(1) AC and EMG Interference might cause mistakes in reading P Wave and Q Wave;
baseline drift might cause misunderstanding in reading ST Segment and T Wave.
(2) Measuring error might occur due to blur endings of S Wave and T Wave.
(3) Low voltage might cause the measurement result of HR not reliable.
(4) Low voltage might cause the ECG coordinate axes calculation or QRS not reliable.
(5) Multi arrhythmia might make it difficult to recognize P Wave and the relative
parameters might be unreliable.
