You can choose to superpose the beats of a single lead or of all leads. The superposition of all
leads makes the position of the 6 mark points more accurate. (As Figure 72)
Figure 72
6 mark points are as followings:
P1: the start position of P wave P2: the end position of P wave
Q: the start position of QRS wave S: the end position of QRS wave
T1: the start position of T wave T2: the end position of T wave
When you adjust these points, the corresponding results will change. When you think that the
current case is not Sinus bradycardia, you can superpose or exchange P1 and P2, then the data
related to P wave will be cleared. Notice: don’t confuse the sequence of the six mark points.
You can adjust gain and speed to magnify the waves on the screen to observe waves more
conveniently. (As Figure 73)

The data which are read automatically or recalculated are displayed in the list box in the bottom
right corner, including:
l. Heart rate (bpm) 2. P duration (ms) 3. QRS duration (ms)

. T duration (ms) 5. PR interval (ms) 6. QT interval (ms)
