I am normally slightly tachycardic, 115bpm is my normal hr. heart skipped beats yesterday so went to er. dr said ekg was normal. how can it be normal?

The doctor probably: meant that the conduction and depolarization and repolarization was normal without evidence for infarction, ischemia or hypertrophy. He/She probably didn't really think of the rate as being anything concerning and that is why he/she said it was normal. Actually he/she should probably have said "Sinus tachycardia otherwise normal."

EKG: The EKG may have missed skipped beats because it is a short recording of the electricity in your heart. If you continue to have symptoms, ask your doctor to do a Holter monitor study which is a 48 hour study that should detect any unusual beats. All the best.
