I could not be converted with adenosine, but
diltiazem was successful. I was sent home the first time with extended-
release diltiazem, which did not work and my heart jumped back into tachycardia that last approximately 11 hours before ending up in the ED again. Echocardiogram revealed no abnormalities and cardiologists scheduled me for an ablation the following week.
I had the ablation done in May and have not, thank God, had an SVT episode since.
