My GP contacted the local endo with my latest bloods & she agreed I am hypothyroid despite 100mg T4 alternating with 125mg,after I asked for free T3 to be checked to see if I had a conversion problem as I am suffering from physical & mental fatigue,lethargy,weight gain,thinning hair etc etc
T3 was prescribed.
After posting my blood results on here I started to add T3.
I dropped T4 to 50mgs alternating with 75mg.Should I have cleared my system of T4 first?
After 2 days adding 5mg of T3 twice a day,on Wednesday I had an occurence of supraventricular tachycardia.I have been having these for 50 years,but this has always resolved after 15-45 mins apart from once in 1997,which is what led to me being diagnosed with an underactive thyroid & Hashimoto's.
After 5 hours of my heart going twice its normal speed(ie over 135 BPM,I phoned my GP & was told to go straight to A&E.The tachycardia stopped 8 hours after it began.I was kept in overnight & put on a drip & my heart & BP was monitored.
I am at a loss as what to do now,as obviously I am reluctant to repeat this,although the cardiologist has assured me I am not in danger & I am not damaging my heart when in supraventricular tachycardia even for several hours.
Today its as if my heart has run an 8 hour marathon with chronic fatigue.All in all,a very unpleasant experience.
However,I do not want to spend the next few years like this,in hypo that is not being treated successfully.
