| augmented lead | Electrocardiogram recorded between one limb and two other limbs. The augmented lead are designated aVF, aVL, and aVR for recordings made between the foot (left), left arm, and right arm, respectively, and the other two limbs. (05 Mar 2000) |
| bipolar lead | A record obtained with two electrodes placed on different regions of the body, each electrode contributing significantly to the record; e.g., a standard limb lead. (05 Mar 2000) |
| black lead | Plumbago; graphite.It leaves a blackish mark somewhat like lead. See Graphite. Source: Websters Dictionary (01 Mar 1998) |
| red lead | A bright orange-red powder that turns black when heated; used in ointments and plasters. Synonym: red lead, red oxide of lead. (05 Mar 2000) |
| red oxide of lead | A bright orange-red powder that turns black when heated; used in ointments and plasters. Synonym: red lead, red oxide of lead. (05 Mar 2000) |
| CB lead | A bipolar chest lead with the negative electrode placed upon the subject's back. (05 Mar 2000) |
| V lead | A unipolar lead with the central terminal as the indifferent electrode; V is the symbol for unipolar (Latin "U"). (05 Mar 2000) |
