Hi Billo327. So have you ever had any cardiac related symptoms during flight or upon landing? I have cardiac symptoms of unexplained origin during decent, and upon landing. They were severe with my most recent flight. I recovered after three days. My aneurysm is stable at 4.3. Has anyone else experienced this, or something similar? I am interested in Billo327's question because I love flying, and now I am very very apprehensive about doing it. Thanks for the question Billo327.
