I have just had a phone call from my key worker at the hospital who has made an appointment for me tomorrow to go for a ECG. This was not expected or talked about previously. She said there is nothing to worry about but it all seems a bit sudden to me. I have felt breathless, unwell and very tired the past few weeks. My medication changed to venlafaxine about 4 weeks ago. I find it difficult to go out and only really go to the hospital 3 times a week. I am so scared now. Is there anyone else who has been sent for an ECG at very short notice?
