My cardiologist put me on Lorazepam. I take 1/2 of a 5mg tablet during the day if I am anxious and sometimes full one at night. I totally agree that the mental strain of dealing with Afib/Aflutter is worse than the doctors realize. I have just completed my 4th ablation at UCSF and am one month post ablation. I have had 5 episodes of Afib, two of which landed me in the ER. Fortunately, I converted on my own. The last 3 episodes I have converted on my own at home but they last for at least 45 minutes. My cardiologist also recommended taking Diltiazem during the episodes. I am frustrated, anxious and feel like a prisoner in my own body. When I am not in an episode, I feel absolutely fine. Sure wish there was a real true fix for this.
