I was diagnosed about 5 years go now by having a cardio call fitted. I had one episode that last a second or two and on the back of that was told I had Afib.
However every ECG I have had has never shown Afib present. Last week my HR went to 170 and lasted until I went to hospital and had an ECG again. No trace of Afib only tachycardia which went back normal on its own after a little while.
Is there a possibility I have been misdiagnosed or just that it can't always be seen on an ECG. Thanks
