Chapter 3 Preparing Work before Using
3.1 Electrode Placement
Notice: The placement of electrode is the basic of holter recorder collecting ECG data signal. The quality and position of electrode affect the quality of ECG signal. Please read this chapter carefully before first operation. The conductive part (applied part) of electrode should not contact with other conductive parts or the earth. Signal input/output part can be connected with the specified instrument only, please contact our company for any replacement. Position of the electrode placement is shown (as Fig.3-1).
Fig.3-1
Page 22
1
Deal with the skin When attaching and placing the electrode, we need to deal with the skin at first, and be sure to clean the skin. Use 95 % alcohol to scrub the skin, after the alcohol evaporates, use abrasive paper attached to the electrode to wipe the attached place to remove cuticula on the surface of the skin in order to reduce the resistance from the skin and the disturbance from the EMG. People who have much hair need to shave it to ensure the skin well connected with the electrode. The skin of old patients is dry and has many crinkles, so we have to clean the skin and make the attached place flat. If the attached place is near the bosom of the woman patient, electrode and cables should be covered by the bra and then fixed well.
Place the electrode Use high-quality ECG electrode to attach the right place and connect with the correspond electrode. To prevent the electrode drop and the baseline excursion caused by pulling, use the medical adhesive belt or plaster to fix every electrode and cable properly. After the cables get together, use the adhesive belt to fix in the abdomen; the rest cables can be tucked into the recorder's waistband. Don't use the common adhesive belt to attach the cables for fear of dirtying, corroding the cables and reducing the usage life span. If use the device in the environment of high temperature or easy perspiring, "EKG Medical Gel" could be wiped on the skin around the electrode beforehand.

T Wave alternation analysis module
Click
T wave alternation (TWA) is a periodic beat-to-beat variation in the amplitude or shape of the T
wave in an electrocardiogram, and the variation of the amplitude is ≥ 0.1mV. TWA is a
important index on judging and preventing Arrhythmia. The analysis adopts TWA measure basing on the maximum of T wave. The general method is:
choose continuous 8 (16, 32 …128) waveforms, number QRS waveform from the first one, such as 1, 2, 3, ……, 8, then compare the maximum of T wave. If the difference of T wave is larger
than the range that has preestablished, there is TWA phenomena. After comparing, carry out
superposition of the singular number (1, 3, 5……) wave and superposition of dual number (2, 4, 6……) wave respectively, then draw the result after superposition, it will be more obvious as

The green line is the superposition wave of the singular number, the red line is the superposition wave of the dual number. If there are red words below wave, it means there is TWA phenomenon for this lead (such as II-lead on above the picture). The number express the height difference after superposition of the singular number wave and superposition of dual number wave.
