“Can you still have heart problems if your ECG is normal?”
I had an ECG test yesterday. Results were normal. Can you still have heart problems if your ECG is normal?

An EKG is reflective of a steady state. Unless you have had a heart attack you may have a normal EKG at rest. Provocative test like a treadmill stress increase the sensitivity of picking up a blockage but a treadmill stress test is only 70% sensitive (30% are missed). A stress nuclear or stress echocardiogram improves the sensitivity to 80-90%. Hope this helps!
