Can Experiencing Faint Ringing I Ear, Cold Reaction To Adenosine?
I had a cardiac MRI scan today and when they injected the adenosine if felt like I couldn t breathe and I felt faint with ringing in ears, and then felt freezing cold and trembling. I m 55 female wih recently diagnosed high blood pressure and left bundle branch block. I experienced tightness in my chest in April when at rest after a brisk walk on a very warm day.it lasted only a couple of minutes. Was the reaction today to do with an underlying problem or merely shock reaction to the adenosine?

Thank you for your question.
I understand your concern. Since you describe your symptoms as occurring at the time you got an adenosine injection, it does seem that what you felt was a mild side effect of the medication. Adenosine has a tendency to cause bronchospasm or in other words a spasmodic contraction of your airways. The other symptoms you described may also be due to adenosine.
Are you on any particular medications at present? Do you still experience any tightness of the chest like before? Please do get back to me for further clarifications. I believe you hav no reason to worry though it would be prudent to inform your cardiologist about your symptoms and hence your doctor will be more cautious in case adenosine is required again.
I hope this has put you at ease.
Take care.
