The heart rate is slower than 60 beats per minute and in a
normalNormal saline flush rhythm (sinus bradycardia)
abnormal T waves refers to changes in your T waves on the EKG. This is a very non specific finding. Depending on the clinical circumstance I would consider ordering tests appropriate to the reason the EKG was ordered -- like a stress test if there was any recent chest pain.
You should see your doctor to discuss any symptoms you be having.
I hope this helps.
