I was diagnosed with this condition as a teenager and had catheter ablation surgery to prevent tachycardia episodes (pulse would regulary shoot up to 150+ beats per min). I am now 31 weeks pregnant and a little concerned that my condition will cause complications during delivery. I have yet to discuss delivery options with my consultant and don't want to have a c- section if it's not really necessary as I hate being laid up and in hospital. However, if it's safer then of course I will ask for one. Does anyone gave any experience of his condition? I have had a few minor palpitations in the last few weeks but I am not anaemic and in otherwise good health. I am terrified labour will bring on tachycardia and the baby may become distressed.
