Hi I had sharp cp under my L breast yesterday a few times. I am 20 and am generally healthy but have strong family history of heart disease so was concerned by this. I had an EKG done today, HR 72, and am getting it interpreted by a cardiologist on tuesday. I am a little worried though and would like to have an idea if anything is wrong before then. The computer written diagnostic read: Warning-artifact in part of recording- use interpretation with caution. sinus rhythm, vertical axis, minor right pre-cordial depolarization disturbance, consider juvenile and/or feminine pattern. small negative T in V3 with flat or low negative T in V2. normal variant of ECG
