In 2013, the FDA recommended that physicians and other health care professionals consider the risk of torsades de pointes and other fatal heart rhythms associated with azithromycin use when considering treatment options for patients who are at risk. It noted the risk of QT prolongation with azithromycin use.
I have SVT and occasional afib. My pharmacist and cardiologist advised me not to take azithromycin anymore, which for me, is kinda a big deal since I'm allergic to penicillin and bactrim. But it can definitely cause problems. I would not anticipate any long lasting problems though..when it's out of your system you should go back to normal.
The medication issue aside, svt and palps are not necessarily the same thing. SVT is generally a steady but rapid heart beat often in the 200s. It starts and stops in one beat. The exceptions to this might be if one had afib where their heart can be irregular or if one had runs of pacs. Do you know what kind of svt you were diagnosed with and had corrected? Do you know where they ablated? Often times a person with a history of svt, corrected or ongoing, can have what is called ectopic beats. These are spots in the heart that fire off an extra beat. In the atria they are pacs and in the ventricle they are pvcs. You state you felt 2 or 3 palps per minute which leads me to believe you were possibly feeling pacs as opposed to it being anything related to your svt. Having a cold, taking medicine, caffeine and stomach issues could bring them on. Stress and anxiety can bring them on as well. It is not a sign that a person's svt is returning. They are extra beats that can return at any time once they have being activated for any number of reasons. In any otherwise healthy heart they are not a threat. Especially in small numbers where a person only feels a couple a minute. It feels like a lot to us but it isn't going to tax out the heart like an untreated svt episode with the heart beating into the 200s can. I can't say for certain what you were feeling but unless you had afib, it is usually called afib and not svt, then odds are you were simply feeling ectopic beats and it is nothing to worry about. Considering the meds seemed to coincide with them odds are them meds caused them and for your peace of mind stopping them may be a good idea. As well, considering the other posters comments the meds themselves may pose some risks to consider. Hope you are feeling better soon.
Just came across this searching for what this weird break out on my lips could be! I was on accutane for a 6 months but never had any issues. I started using EOS ball lip balm and then their tubed vanilla chap stick. I noticed the first few clear to red, itchy tiny bumps on my bottom lip. Then I noticed a few clear on my top. I did not even think it was EOS, I totally thougth maybe it was from the Accutane. But now I realize that the bumps started after I received the EOS ball for christmas. I had stopped using the it as much and noticed, the bumps were subsiding. However, I grabbed a pack of the vanilla tube EOS and have been using them and BAM, my lips are red, itchy and the bumps ... I can feel them again! UGH What the hell. Everyone who has commented on this and experienced these bumps and used EOS, should write them an email and warn others!
