I just received a phone call from my cardiologist (actually a cardiac electrophysiologist). He called to review my Nuclear Stress Test results. All good news! Stress test itself showed no arrhythmias and the tomographic images showed good blood flow to the heart. This indicates that the arrhythmias are not life threatening. This is what I expected, but still good to have positive evidence :-). I’m still going to do the cardiac MRI next week to rule out any other issues. I’ll post those results when I have them.
