Abstract:
Objective To compare the ECGs recorded from 2 different reference points on guinea pig body surface. Method ECGs were recorded synchronously from each of 18 testing points distributed in 3 intercostal planes cross the body surface of 30 full-grown guinea pigs, using the central terminal and the right forehead as 2 reference points, respectively. Comparison was made between the 2 groups of ECG R(r) wave amplitude from each of 18 points. Results R(r) wave amplitude with the right forehead as the reference point was significantly larger than that with the central terminal as the reference point (P<0.05). Conclusion The reference point for ECG recording on the right forehead is superior to that on the central terminal.
