Does anyone else have symptoms of irregular beats and ectopic beats when lying down. I had a perfectly brilliant day yesterday, busy at work and enjoyable evening. Lay don in bed and my heart went into an irregular beat, stronger beat and I felt sort of unwell-hard to describe. This happens frequently. I find lying on my right side makes it worse. I am getting to the stage where going to bed is something I am almost anticipating will cause a repeat of these symptoms. I take no drugs for my SVT and in March and April only had 2 episodes in each month lasting no more than 2-3 minutes.
