Can an EKG and Holter Monitor be wrong?

[TheWethan]

I've recently been experiencing shortness of breath, heart palpitations, an increased heart rate (normally about 90-120,) and feeling faint and/or like I have to pass out. These symptoms happen most of the time but with constant shortness of breath, sometimes my heart rate is normal etc... I was referred to a cardiologist and he listened to my heart, did an EKG (which came back normal,) and prescribed me a Holter moniter which came back with nothing abnormal. He is convinced it is a psychological problem since these symptoms got worse after I had a gallbladder removal surgery, BUT these symptoms (shortness of breath and occasional passing out feeling with  heart palpitations) were there before just minor and didn't bother me much. Could it still be a heart problem or is he right? Should I see another doctor? Maybe another specialist?

The ekg and holter monitor cant be inaccurate, but they can be inconclusive if you don't have an episode while wearing them.

2 options exist, a 2 week 'event monitor' and a 2 year implanted monitor.

However if you experienced symptoms while wearing a holter the results are likely accurate.
