These additional leads are V3R, V4R and V7. V3R and V4R are used in children under the age of 5 years due to the fact that their right ventricle is located to the right of sternum. Thus, normally, in the precordial leads there can be no ST-segment elevation (or an elevation of less Figure 1. Electrocardiograms Showing Normal ST-Segment Elevation and Normal Variants. Tracing 1 shows normal ST-segment elevation. Approximately 90 percent of healthy young men have ST-segment eleva-tion of 1 to 3 mm in one or more precordial 2021-04-06 The Fontaine bipolar precordial leads are placed at the manubrium of sternum, xiphoid, and V4 positions using the right arm connection, left arm connection, and left foot connection, respectively. Epsilon waves are detected by: 1) Standard 12-lead electrocardiography (S-ECG) 2) Right-sided precordial lead electrocardiography (R-ECG) 2021-01-20 · A precordial lead is one of the leads placed on the chest for an electrocardiogram. A precordial lead refers to one of the six standard electrocardiogram (EKG or ECG) leads, or electrodes, placed on the chest in order to obtain a 12-lead EKG report graphically showing the heart's electrical activity.

Hence, the chest leads are excellent for detecting vectors traveling in the horizontal plane. EKG Precordial Leads These six unipolar leads, each in a different position on the chest, record the electric potential changes in the heart in a cross sectional plane. Each lead records the electrical variations that occur directly under the electrode. Precordial leads The precordial leads lie in the transverse (horizontal) plane, perpendicular to the other six leads. The six precordial electrodes act as the positive poles for the six corresponding precordial leads: (V 1, V 2, V 3, V 4, V 5, and V 6). Wilson's central terminal is used as the negative pole.
