I have been having episodes of sinus tach which usually occurs when I am walking or standing up (determined this by doing orthostatics). I have a history of heart block & have a pacemaker that was put in in '05 for complete heart block. I often feel lightheaded, dizzy, have chest pain, L arm pain & a headache. I also get palpitations a lot.I have been in the hospital several times for this. EKG shows a 100% paced rhythm (normal for me), blood work, chest x rays are normal. I've had 2 echos & 1 stress echo in the last year which showed a EF in the mid 40s. I was always in the 70s so this is a large drop for me. My EP is considering doing an ablation to treat my rapid heart rate b/c I am not responding to Cardizem. I was on Nadolol & Toprol XL before being switched to Cardizem. I had my device checked in Aug 2011 & everything is working perfectly.
I started taking Lamictal in April of 2011. I take it for depression & it works great but I am just wondering if it could be causing the dizziness, chest pain, L arm pain, headaches, rapid HR, & palpitations.
