@lisalucier I have a question regarding Keppra. Is Keppra a medication that an adult post menopausal woman should be on? I believe it is causing SVT, and my doctor says thats not possible. I was put on the medication and these things started occurring. I have no heart issues, no family heart issues, and I have read that AEDs can cause this in people with Epilepsy. I am just not getting anywhere with my doctor on this and need any input or information one can provide.
