What are the side effects of Adenosine when administered to a person with an already existing cardiac problem?

Hi,

Welcome to icliniq.com.

I understand your concern. Why is a stress CMR (cardiovascular magnetic resonance) test advised? Did you have chest pain? Stress CMR is done to assess cardiac muscle viability and function and to see previous heart attacks. Adenosine's side effect is that it can cause shortness of breath in those with asthma. Another side effect is that it slows the heart rate. But Adenosine is infused in a controlled setting, and after stopping the infusion, the heart rate returns to normal within a minute or two. So there is very minimal risk associated. Kindly revert with reports. Thank you.

Hi,

Welcome back to icliniq.com.

I understand your concern. T wave (attachment removed to protect the patient’s identity) is the most non-specific wave for ischemia assessment. T waves can be flattened in low potassium levels in the blood. It may also be a normal variant. ECG (electrocardiogram) is always interpreted in the context of clinical history. Regarding your query about Adenosine, it can precipitate asthma in asthmatics. It can slow down the heart rate for a short time. In the case of ischemic heart disease, it can cause chest pain. The effect can be reversed with Aminophylline injection, which is available with Adenosine always. So there is nothing to worry about. Thank you.
