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.

Episilon wave

• arrthmogenic right ventricular cardiomyopathy(ARVC, ARVD)
