I'll try to keep this short. Hubby had a ECG in docs office, it showed no p waves. I understand, kind of what a Pwave is, when your heart "resets" itself before the next beat. Anyway on April 20th he has to have a bunch of test, including holter, ultrasound of heart and stress test and complete lipid tests. It must not be an emergency since its schedule for a month away, but can anyone tell me what this could mean.......not resetting itself? oh yeah, blood test emzymes show normal levels to not indicate a prior heart attack.
