Giggity. I m not sure what you would be suing the doctor for? The OP was aware of the deficiency from the first forum and then tried a different forum where the deficiency was confirmed but a second test was passed on the day. Not much difference from passing your ECG and then having a cardiac event the following week? The test simply gives a result, it isn’t a guarantee of anything. I don’t know, but very much doubt the administering clinician provided recommendations for flight training based on the result of a test?
