[A study on location of poles of terminal leads of ventricular fractionated potentials].
To eliminate the electromyogram-noise-signal from recording ventricular fractionated potentials (VFP) of the terminal leads(TLs), the multi-locations of leads were used to record ECG and VFP in 36 cases of controls and 68 cases of coronary heart disease. It was shown that the electromyogram-noise-signal could be minimized when TLs located separately at the point of infraclavicular cross lines axillaries media and the point of upperinguen cross lines axillaries media, and the essential formation of the ECG and VFP signals could not be changed except the QRS potentials becoming higher.
