Hi, I'd really appreciate it if you could take the time to answer the following 10 questions relating to you, so as it could perhaps help form a picture of common traits between sufferers of PCS.
EDIT* August 28th 2011. Thank you to all of you who are participating in the questionnaire. New questions have now been added and old ones removed. I know some are a bit strange but I'm just trying to rule out things that I anatomically suspect influence / have a bearing on the function of the heart. Check back again as I will refine the questionnaire in due course according to patterns and suggestions which you can make on the forum page.
