Electrolyte solutions for inappropriate sinus tachy?

Hi there! I was recently diagnosed with IST, and luckily I am only slightly symptomatic (hooray!). The only thing that has particularly been bothering me is dizziness.

When I was waiting around for a cardiology appointment, I decided that the dizziness felt like the last time I'd had a gastro bug (minus all other symptoms), and since gastrolyte made me feel better last time I thought I should try it again. I felt better pretty much immediately (hooray!). I've tried it a few other times and now keep some in my handbag for emergencies.

I've been saving the eIectrolyte solutions for only the really bad dizziness because I don't know if is ok to take it regularly without any gastro symptoms. I dont want to mess up my electrolytes or anything. I tried to ask the cardiologist but he successfully distracted me lol.

Does anyone know whether it is it ok to take electrolyte solutions regularly for this?

thanks!

I forgot to say - I had a blood test so apparently I'm not dehydrated and my electrolytes are normal
