So I discussed my symptoms with my cardiologist. He wants to first do a "Stress Echocardiogram threadmill" test, before doing an angiogram. My pulmonologist ordered an arterial blood-gas test which would give an indication if im ok to fly again.

She and my cardiologist also suggested to have the CTA Chest scan done to make sure I have no more blood clots in my lungs. I have that scheduled for Monday.

But I'm still wondering if they should just do an angiogram and get it over with. Last night I wore a small oximeter which records my pulse and oxygen levels continuously throughout the night.

Two times last night, it alerted me of a low heart rate. I woke up and it showed HR of 45bpm for about a minute, then spiked to over 100bpm when I moved around and sat up. This has to be related to my "panic" attacks.

I sent a message to my doctor on what happened.
