SysName REFID Mnemonic Description PART CODE10
12-lead, unspecified | ECG, lead system | Heart | CVS MDC_ECG_LDSYS_12LD_UNSPECIFIED SCP_12LD_0 Unspecified. Systems that do not record the electrode placement information should use this term. 10 11264
12-lead, standard | ECG, lead system | Heart | CVS MDC_ECG_LDSYS_12LD_STD SCP_12LD_1 Standard 12-lead positions: RA, RL, LA, and LL are placed at limb extremities. V1 to V6 at standard positions on the chest. All electrodes are placed individually. This lead positioning supports the standard 12 leads I, II, III, aVR, aVL, aVR, V1, V2, V3, V4, V5, V6 and the Cabrera 12 leads aVL, I, aVR, II, aVF, III, V1, V2, V3, V4, V5, V5, V6. 10 11265
12-lead, Mason-Likar | ECG, lead system | Heart | CVS MDC_ECG_LDSYS_12LD_MASON_LIKAR SCP_12LD_2 RA, RL, LA, and LL are placed on the torso (Mason-Likar positions). V1 to V6 are placed at standard positions on the chest. All electrodes are placed individually. 10 11266
12-lead, V-Pad | ECG, lead system | Heart | CVS MDC_ECG_LDSYS_12LD_VPAD SCP_12LD_3 RA, RL, LA, and LL are placed on the torso (Mason-Likar positions). These limb electrodes are individually placed. V1 to V6 on the chest as part of a single electrode pad (V1 to V6 are NOT placed individually). 10 11267
12-lead, Pad | ECG, lead system | Heart | CVS MDC_ECG_LDSYS_12LD_PAD SCP_12LD_4 RA, RL, LA, LL, and V1 to V6 (all electrodes) are on the chest in a single electrode pad (such as Omnitrode). (None of the electrodes are placed individually) 10 11268
12-lead from Frank XYZ | ECG, lead system | Heart | CVS MDC_ECG_LDSYS_12LD_FROM_FRANK SCP_12LD_5 12-lead ECG is derived from Frank XYZ leads 10 11269
12-lead, non-standard | ECG, lead system | Heart | CVS MDC_ECG_LDSYS_12LD_NON_STANDARD SCP_12LD_6 12-lead ECG is derived from non-standard leads 10 11270
12-lead, bicycle | ECG, lead system | Heart | CVS MDC_ECG_LDSYS_12LD_BICYCLE Standard leads for bicycle exercise testing in Europe (Germany, Finland,..) where bicycle tests in upright position are performed the limb leads are often positioned not on the chest (Mason-Likar), but on the back (shoulder and on the hips) of the patient. Doing this has a practical reason, since the patient bows his back during bicycling and the limb lead electrodes applied on the chest would be disturbed. 10 11271
12-lead, raised intercostal | ECG, lead system | Heart | CVS MDC_ECG_LDSYS_12LD_RAISED_INTERCOSTAL Standard leads one intercostal space higher. The Wilson electrodes are applied one intercostal space higher the limb electrodes remain on their position. I..aVF, V1', V2' ... V6'. 10 11272
XYZ, unspecified | ECG, lead system | Heart | CVS MDC_ECG_LDSYS_XYZ_UNSPECIFIED SCP_XYZ_0 Unspecified. Systems that do not record the electrode placement information should use this term. 10 11273
XYZ, Frank | ECG, lead system | Heart | CVS MDC_ECG_LDSYS_XYZ_FRANK SCP_XYZ_1 Frank lead system (Frank, E., An accurate clinically practical system for spatial vectorcardiography. Circulation 13:737, 1956). 10 11274
XYZ, McFee-Parungao | ECG, lead system | Heart | CVS MDC_ECG_LDSYS_XYZ_MCFEE_PARUNAGO SCP_XYZ_2 McFee-Parungao lead system (see Benchimol, Vectorcardiography, Williams & Wilkins, Baltimore, 1973, Fig 1.6 on page 6) 10 11275
