I'm having tachycardia issues
I'm new to this group, but not new to Connect. I'm having dizziness when I walk for exercise, and I've had tachycardia for quite some time, my doctor has ordered a heart monitor for 48 hours and an echocardiogram. I had my heart tested at Mayo in 2014, so in looking at my old records, I had tachycardia back then even! Is there anything I should know, and questions I should ask next week when I go in for this procedure?
