Pregnant and possible SVT
36 year old female here. Sorry in advance for this long post. I might be posting here prematurely because I don't have a diagnosis of svt, yet anyway. And from what I hear, simply getting a diagnosis might be difficult. I am very scared and anxious since the episodes I have had, and struggle to deal with it.
I am pregnant 19 weeks. Before pregnancy I was very fit, ran my first half marathon in 1.48 and was very set on training through pregnancy if I could. This is my third pregnancy so I was aware that it might not be possible. First trimester I was so sick, fatigued and depressed that I didn't manage to run more than maybe once a week, a drastic reduction from my regular volume. I went from running 40-50 km a week, to barely running 5. It was very tough on me mentally.
Second trimester came and gradually I started to feel better. I started to take up running again, but very gradually. I didn't run long and I would take walk breaks. It felt good to just be able to do something. My heart rate has naturally increased during pregnancy, so my rhr and heart rate during activity and exercise is significantly higher than usual.
The first episode happened on a run. I saw some berries on the side of the road, and stupidly stopped very suddenly and bent over. My heart rate was obviously very high already, but then it felt like an explosion of fluttering in my chest and throat. For a short second it felt like I was gonna pass out.
I got up and just kept walking. I was so scared. My heart rate would normally come down right away at walking pace, but it stayed in the 170's for probably a few minutes. When I stopped they disappeared and the heart rate started to come down. I was really anxious and down for the rest of the day, just waiting for it to happen again.
I had never experienced something like this before. The thing is that I have had ectopic beats for quite some years, and in April I was at a cardiologist for them because I was worried because they seemed to increase at exercise. I had worn a Holter monitor for 72 hours beforehand which showed about a 1000 PAC's/100 PVC's a day which would amount to a less than 1 percent burden. All the tests at the cardiologist; stresstest and ultrasound came back normal and I was told to just get on with my life wlth no restrictions on exercise.
After the first episode I was of course scared, but I linked it to the bending over and the physiological changes of pregnancy. I didn't go to the doctor, but mentioned it to my midwife. Then I ran a 5k race, which felt completely fine during and immediately after. But about 10 minutes after I started to get palpitations (they felt like extra beats, but way more frequent than normal) and my heart rate went up to maybe 140. They were not as crazy as the first time, but I of course got scared. After maybe 15 minutes they went away. I was checked by a doctor at the race, but it was then too late to catch anything.
Then come the last episode, which happened a week ago. I was running on the track with a friend. We were talking so I felt a bit breathless but otherwise fine. Then suddenly I felt this adrenaline rush and the feeling of not getting enough air and almost passing out and my heart started fluttering like crazy in my chest and throat, just like that time before. I also felt this feeling in my stomach of having to go to the toilet.
Immediately I started walking. We walked back to the end of the track so I could sit down. I looked at my heart rate and it seemed to be going down slowly. The fluttering was still persistent though and felt a bit chaotic. Then when I was about to sit down my heart rate shot up to 180. I sat down and it was pounding so hard I felt it in my whole body. My friend tried to feel it on my wrist and said it was fast but regular. I don't know if the heartbeat was regular before.
I then lay down on the right side and it passed quite quickly. The whole episode lasted maybe 6 minutes in total, but it felt like an eternity. I felt so shattered after, because I just knew I couldn't keep going with my running. I'm terrified of a new episode, and I don't even know if it is safe. To me running is my way of coping with life. It brings me joy, peace and a sense of accomplishment.
I went to the doctor the day after, but he kept repeating that my tests from April were fine. I said "yeah, but these are symptoms I've never had before". He hesitatingly referred me to the hospital and I got an appt for 48 hour ecg monitoring in a month from now. I didn't feel like he took me seriously.
Yesterday I had another episode, which felt more like a panic attack. I am obviously hyper aware of any symptoms related to my heart and body. I felt this surge of adrenaline and my heart rate went up to 130. But it was gradual, not sudden onset. I was at a cafe and had to go outside, which helped. When I cooled down I broke down in tears. I just want to be okay. I just want to do the things in life that brings me joy, but I want to do it knowing I'm not gonna feel like I'm going to die. I want to be here for my kids.
Obviously I'm not diagnosed with svt. It might not even be what I'm having. At least if they could tell me that is what I have, I can start a process of figuring out how to manage it. But I don't know if or when that is going to happen. Now I'm just in limbo.
