'22 Leads Test
Enter the letter for the matching Answer
| A. represents the complete ventricular depolarization last (0.08-0.12 secs or 2-3 small sq) anything +/- means "abnormal"B. T ; Unlike a single-channel ECG, the 3- and 6-channel ECG record multiple leads at once producing a 12-lead ECG in about 10 secsC. L. Arm ; positive deflectionD. the placement of the leadE. aVRF. - chest leads/precordial leads V1-V6 provide a view of the heart from different anglesG. - standard leads l, ll, lll produce POSITIVE deflections on the graph
- augmented lead aVR produces a negative deflection
- augmented lead aVL & aVF produces a POSITIVE deflectionH. make sure that the leads are properly placed I. "unipolar lead"J. used to stabilize the ECG but takes NO part in lead formationK. L. Foot (L. leg to the foot) ; positive deflection L. 10 leadsM. 4 limb leads (3 limb electrodes & 1 grounding electrode)
6 chest leads (V1-V6)
= 10 leads that create 12 waveformsN. unipolar
V1-V6 (where you pick up the signal of the heart)O. "bipolar lead" AKA bipolar bc they are composed of 2 electrodes; a neg. and pos. one; ECG records the difference in electrical potential btwn themP. on the R. leg Q. the standard limb leads "bipolar leads"R. lead l, ll, lll & aVL, aVFS. [V]3 GREEN; midway between V2-V4T. the electrical activity in 2 directions (<--->) |
