I'll be praying for you and Zach, Rose. My wife had a different amlady, with similar symptoms. She had SVT. Her heartrate would skyri=ocket to over 200 and we'd have to call an ambulance several time over a few year period. however, the cardiologists couldn't catch the episode "in the act." Eventually, they did and determined which heart problem she had. She had surgery to have the electrical connection in her heart's pacemaker "burned out." It was scary!
