I have suffered from GAD since 2003 and missed heartbeats, ectopics...whatever you want to call them, have always been my most hated anxiety symptom. Like so many other people who have posted, I have had them checked out and have had an ECG and everything is normal, but they still have the power to frighten me. Sometimes I go for days or even weeks without them (bliss!) and sometimes they happen once a day for several days. Sometimes there is just one large thud, sometimes a flutter...and I have read all about them, know the reasons behind them, know they won't hurt me, and know that ideally I should just ignore them because most people get them at some point. I can only say - you are not alone - reading these forums helps me enormously because so many people describe exactly how I feel about them and knowing there are so many of us out there is a big support. This is my first ever post - I started to surf the site again tonight because I had a 'flutter' after days of being free from the missed beats. Please just know that ultimately they won't hurt you - I have had them on and off for seven years and am still here!!
