Sinus tachycardia

[TSJ19]

Hi I have Sinus Tachycardia which is usually kept under control with Beta Blockers.
I avoid caffeine and alcohol as this will usually set it off. I've just been out for lunch and had a glass of fizzy water instead of still and my heart is currently going really fast.
Could the fizzy water be why?
Thanks

Could be, who knows? It's probably similar to tachy episodes in Atrial Fibrillation which I have. I get runs of tachy up to 180 bpm and there is absolutely no reason for it. If it lasts longer than three hours it's off to A+E for me! But mostly I convert myself back to sinus rhythm with vagal manoeuvres.

My episodes can happen out of the blue, no rhyme or reason, but like you OP I avoid caffeine and alcohol (stimulants as the doc calls them!). But I drink a lot of fizzy water and it doesn't set it off at all. I don't think I can actually pinpoint what does either. Just one of those electrical misfiring faults in the ticker.

Hi, I haven't had one these episodes that's lasted this long for ages and I really don't want to end up having to go to A&E.
I haven't actually taken mine to see how fast it's going as that will make me worse.

If it's still happening, try to cough really hard and explosively. One cough after the other really loud, really deep. Another one is to sit on the toilet and bear down really strongly as if you are straining with constipation. Either of those two usually reset things for me.

But not always, however you could try them, they are called vagal manoevres, I'm taking BBlockers also.

Hope it settles down, as it can be very frightening, but not life threatening really. Deep breathing helps to calm you also, as I'm sure you know already.

Thankyou for your advice I will look up those manoeuvres. It has started to settle now I've sat down but still quite fast.

I get it for no reason, often when fast asleep in bed. Those vagal manouvres work most of the time.
