Exercise physiology: The heart rate normally accelerates with exercise, driven by faster sinus rhythm (indicated on an EKG by P waves.) There are occasionally P waves that come from other places than the sinus node (ectopic atrial rhythm.) It sounds like you've already had some testing. These little boxes aren't big enough for detailed analysis; consider an Inbox Consult with a cardiologist here.
