I have a appointment with the hyperbaric specialist (pulmonologist) but its not until next month. I was able to locate some of my records when I had a sleep study and then seen a cardiologist with no further treatment needed. I wasn't aware of the hypoxemia. Maybe that was diagnosed from the sleep study?

CURRENT DIAGNOSES
1. Bradycardia, 421 .89
2. Hypoxemia,799.0

The patient's mean heart rate was 74 bpm with a minimal heart rate of 39 bpm and a maximal heart rate of 128 bpm. The patient's underlying rhythm was normal sinus rhythm with the minimal and maximal heart rates corresponding with sinus bradycardia and sinus tachycardia, respectively. No evidence of any pauses was noted. No ventricular ectopic beats were noted.
Four supraventricular ectopic beats were noted. These represented premature atrial contractions. The patient noted no symptoms during the duration of the Holter monitor.
SUMMARY:
1. Underlying sinus rhythm with occasional sinus bradycardia and sinus tachycardia.
2. No ventricular dysrhythmias noted.
3. Rare premature atrial contractions noted. No evidence of supraventricular tachyarrhythmias noted.
4. Relatively unremarkable 24-hour Holter monitor.

For the Echo

CONCLUSIONS:
1. Overall preserved left ventricular systolic function. Left ventricuiar ejection
fraction is 55% to 60%.
2. No evidence of previously seen small apical muscular VSD by both color flow Doppler as
well as agitated saline study.
3. No significant valvular abnormalities
 
looks like you already had the bubble test done
-that's what the agitated saline study is
-which means your previous small apical VSD has either:
1) Closed
2) Is very small with no detectable Right to Left shunt

You should still go for your appointment with your dive physician but there shouldn't be any issues with diving.

Cheers!
