I haven't been on here in awhile and obviously this post catches my attention. Don't forget I went into full cardiac arrest on 4/18/08 from a ER IV dose of Labetalol and Cardizem to treat my AFIB. After being intubated for 2 days and my family being told I either wouldn't make it or if I did I would be a vegetable for the rest of my life I've made an awfully nice comeback. My EF went from 10% after the cardiac arrest to 48% as of my last Echo in Jan this year. Now that I am in NSR My LV has SHRUNK in size back to normal after being severely enlarged. My coronaries were perfect when they did the heart cath while in ICU for 15 days. I have been in NSR for about 1 1/2 yrs now on Sotalol was on Amio for awhile and converted to Sotalol. Docs have no explanation how I lived more or less how I have made a full comeback. Take your AFIB very seriously bro.
