SVT & Ablation

I had my first SVT after being hospitalized for Congestive heart failure with severe edema. I was in my room reading my tablet when a huge group of nurses came in, along with 2 doctors and a crash cart. They kept staring at the monitor. I had no idea what was happening but they told me I was in V-tac. Scared the daylights out of me. I was then transferred to the Heart Center at our Medical Center. It settled itself after being transferred. I lost almost 40 lbs of fluid and have been feeling better since then. I was also placed on Entresto.

I wear an Apple Watch 24/7.

Wow that’s amazing I’m so happy for you..and to know that your not on medication is fab.. in my case I was diagnosed 10 weeks ago with PSVT… I recently went to cardiology for a repenting check up and while I was there I had two bad episodes so thankfully the hospital and doctors could see first hand what I go through..I had to stay in for 3 days while they monitored me and to see if I have anymore episodes which I don’t thankfully but they have suggested the ablation which i definitely want as I’ve done so much research into this.. but while I wait more tests they have put me on bisoprolol and omg have o felt rubbish on them… it’s been 9 days and for the last few days my blood pressure dropped and I felt woozy and fatigued and just felt low.. I’ve been told it takes a while to get in your system but can anyone give any advice.. I’m only on a low dose of 2.5 but wow it makes you feel pretty rubbish x

All of the calcium channel blockers and beta blockers can suppress the heart's rate when the heart is NOT in arrythmia. This is one of the well-known drawbacks of such blockers... when the heart is willing to play nice for several days or longer, those chemicals can have something like a cumulative effect and they will make the heart go into official bradycardia territory (technically, any HR lower than 60 beats per minute is considered bradycardia). However, there are many people whose normal HR is far lower when calm and at rest, such as when reading a book or watching TV. I'm talking about an HR running between 38-50 BPM. My own when I was younger and a competitive runner was 38!. God knows what it was when I was in deep stages of sleep!
Anyway, you say you feel listless and not very chipper? It is probably the blocker. Your dose is the lowest given typically for bisoprolol. Otherwise, it might be an arrhythmia that you don't sense. Arrythmias, all by themselves, can leave you breathless, foggy, anxious, not wanting to do anything except to fret, even feeling faint. This is why self-monitoring for your heart's rhythm is important. If you're not symptomatic when in arrhythmia, in your case it's a tachyarrhythmia, and you feel nothing that alerts you, you may still get the sensations of being listless, out of breath, etc.

I have comment above, but would say, have the ablation, knock wood it’s been 5 years since and I workout play sports and it has not come back. You will be glad you had it done. Keep in mind although you feel great right after the procedure, it takes a good 6 to 8 months to be completely back to normal! Good luck

I am 74 years old and have SVT. I have had it for years. Recently experiencing long episodes of 115 bpm . Can’t seem to get them under control. I have a heart monitor on for a 7 days. Not sure if stress is making it last all day.

Are you taking any supplements or prescription drugs? The timing may be key here if it's either one of those...when you take it, when it enters your system in a sufficient concentration, and then it has the effect. Or, it's an activity....maybe a diurnal/cyclic hormone like somatotropin, maybe its a wonky thyroid. There are literally scores of 'triggers' that people report and swear sets them off at least 60% of the time.
Have you had your magnesium levels checked? Potassium and sodium? They are key for proper heart rhythm.

I take magnesium supplements daily and I recently had extensive blood work done and everything is within normal range. I have a history of anxiety and panic attacks which don’t help the situation. I am trying to keep a record of what I have eaten and when it happens. I thought sodium might be a big factor and hydration.

I am on Diltiazem and I take it in the evening. I used to be on Metoprolol and it seemed to have controlled it better. I will talk to my cardiologist.

I too was on Metoprolol along with Lisinopril. Plus, Diltiazem to be used if an episode lasted more
than 15min. I had 2 lengthy episodes although those 2 meds in general seemed to work. So my cardiologist sent me over to see my EP. He suggested ablation or substituting Met & Dil for Sotalol. Monitored me with ZIO for the 1st 7 days of the new med. So far so good but it’s only been 3 weeks. I am leery of the ablation as my sister had a bad reaction to it, although everyone is different. You might need to jut increase the Metoprolol as that seemed to work for you. I was on 100mg AM and 50mg PM. Hang in there!!
Your not alone but it can be really scary 😱
