I am a 55-year old woman. I was first diagnosed with paroxysmal svt at age 7. It has never been much of a problem, but as I have aged, I have worried enough about it to make sure my doctors are all aware of the condition. I have had many ekgs, echos, worn a holter monitor, had every kind of stress test, but it wasn't until April that the svt was actually seen on an ekg. My internist freaked out, wanted to put me on Toprol immediately, but I resisted, since I knew that my irregular heartbeat could be back to normal by the time I reached the parking lot. I did heed her urging to see a cardiologist (two in fact), which led to an ep study, with the hope of a radio frequency ablation on August 5. I have been taking a full strength aspirin since April to decrease the slight risk of stroke during an svt episode. The ep study showed that the electrical problems in my heart were in places that made an ablation too risky, so nothing was done, but the doctor advised me to try Toprol (25 mg) for a month "and see how I liked it." I had my first dose in the hospital on Tuesday, August 5, and proceeded to take it as prescribed. By Thursday afternoon, I felt oddly on the verge of tears. On Friday, both of my knees were hurting, by Saturday evening, I was in bed feeling like I had the flu. Every joint in my body was aching. Sunday morning, I felt even worse. I found this website and decided to stop taking the medication at that point. Today, Thursday, August 14, is the first time I have felt vaguely like my usual healthy self. After stopping the medication, I had 2 episodes of svt, lasting about 10 hours each. I have had excruciating stomach cramps, headache, inability to sleep, depression. This is after taking it for 5 days!! My heart (no pun) goes out to those of you who suffered for months on the drug and then even more months off of it. I know it helps many people, my mother included, but thank goodness that those of us who have a bad experience have a place to realize that we're not crazy.
