I had an abdominal CT scan a few years ago. I was very nervous when the nurse brought me my prep to drink and prepared me for how I would feel during the dye injection. I was completely blind sided. I also suffer panic attacks...frequently in medical situation that are new or unpleasant. So when they injected the dye I was extremely apprehensive. .Afraid of allergic reaction and so on. My heart began racing,I was terrified and the tech told me I was fine and to remain still. afterward I quickly got up from the table and went in the room next door to calm down and reduce my heart rate. I don t have a heart condition but I have IBD and was diagnosed at 7 years of age. I am now 45...I need to have another CT scan and am still wondering if the contrast caused or can cause the rapid heart rate? Or more likely was it a panic attack. I m wondering if this is common or dangerous. Or do I just tell myself its going to be alright and come prepared with something prescribed by my Dr. to relax.
