| CDISC-2579 | C90412 | C90013 | ECG Lead | LEAD V1 | Lead C1 | A unipolar electrocardiogram lead site; the electrode is placed at the fourth intercostal space on the anterior chest wall (between ribs 4 and 5) to the right of the sternal border. In small animals, it is placed at the right fifth intercostal space near the sternum. (NCI) | Lead Site V1 | Add synonym. | ||
| CDISC-2579 | C90414 | C90013 | ECG Lead | LEAD V2 | Lead C2 | A unipolar electrocardiogram lead site; the electrode is placed on the anterior chest wall at the fourth intercostal space (between ribs 4 and 5) to the left of the sternal border. In small animals it corresponds to V2-V3 where it is placed at the 6th left intercostal space near the sternum. In large animals it is placed over the 6th rib at the level of the costochondral junction on the left side of the thorax. | Lead Site V2 | Add synonym. | ||
| CDISC-2579 | C90415 | C90013 | ECG Lead | LEAD V3 | Lead C3 | A unipolar electrocardiogram lead site; the electrode is placed on the anterior chest wall midway between leads V2 and V4. In large and small animals, it is placed over the dorsal spinous process of the 7th thoracic vertebra. (NCI) | Lead Site V3 | Add synonym. | ||
| CDISC-2579 | C90416 | C90013 | ECG Lead | LEAD V4 | Lead C4 | A unipolar electrocardiogram lead site; the electrode is placed at the fifth intercostal space on the anterior chest wall (between ribs 5 and 6) at the left midclavicular line. In small animals it corresponds to V4-V6 where it is placed at the 6th left intercostal space near the costochondral junction. In large animals it is placed over the 6th rib at the level of a horizontal line drawn through the scapulohumeral articulation on the left side of the thorax. (NCI) | Lead Site V4 | Add synonym. | ||
| CDISC-2579 | C90417 | C90013 | ECG Lead | LEAD V5 | Lead C5 | A unipolar electrocardiogram lead site; the electrode is placed on the anterior chest wall level with lead V4 at the left anterior axillary line. In large animals it is placed on the sixth ICS on the right side of the thorax along a line parallel to the level of the point of the shoulder corresponding to the electrical center of the heart (central terminal). (NCI) | Lead Site V5 | Add synonym. | ||
| CDISC-2579 | C90418 | C90013 | ECG Lead | LEAD V6 | Lead C6 | A unipolar electrocardiogram lead site at which the electrode is placed on the anterior chest wall level with lead V5 at the left midaxillary line. | Lead Site V6 | Add synonym. | ||
