Electrocardiography
심전도(Electrocardiography, ECG, EKG)
P wave
- 심방의 탈분극
PR interval
- AV node에서 His-Purkinje로 전도
T wave
- The T wave is normally upright in leads I, II, and V3 to V6; inverted in lead aVR; and variable in leads III, aVL, aVF, V1, and V2. Thus, T-wave inversions in leads V1 and V2 may be fully normal
- Upright in all leads except aVR and V1
- T wave inversion in lead III is a normal variant.
