I've always been bradycardic, typically between 50-60/bpm. In the last couple of years, I've been told I have a murmur, but not significant. This year's ECG showed intra-atrial conduction delay (102 ms), moderate right-per cordial repolarization disturbance-consider feminine pattern (442/445 ms), negative T in V2 (61/3646 deg), with a small negative T in V3. Can you explain?
