Hi
I am 38 and for about 6 years have had random episodes of waking out of sleep with my heart racing at 180-200 bpm, sweating, nausea and feeling like something is wrong. normally short lived (1-10 mins).
last night i had the same. woke 45 minutes after going to bed. heart racing at 190 ish. ten mins later was still around 180 another 15 and it was sat at 150. called 111 and ambulance was sent. took an hour to arrive and by then heart rate down yo 100.
After doing ecg they wanted to take me in heart shot up to 130 and stayed there. i put it down to leaving my husband and daughter at home and going into hospital.
in hospital Dr said she had never seen svt at 130 (normally higher) but i was in definitely in SVT and as it was now a few hours since it started suggested i needed Adenosine. I was pretty scared and asked if i had other options. she said we could wait but risked cardiac stress and possible cardiac arrest due to time it had been going on. equally scary. i ended up having two rounds of Adenosine which didn’t work. preparing the third dose she had to go get advice and when she came back heart had slowed to 105. she said she had never seen that happen before. it usually happens immediately or not at all. left it a couple of hours and stayed at 100.
she came to discharge me and said the consultant said it might be rare type of SVT that is present at lower heart rate. but not dangerous because heart isn’t fast so not causing any damage. That left me wondering why i had to have it done i the first place? i wont lie i found it pretty traumatic.
I’m so confused can anyone help me understand?
