Don worry about the same, to get a good MRI picture your heart rate has been on the lower side, doctor s prefer less than 60.  Now for a young guy like you and with s the added apprehension of going through the scan the heart rate would have gone up. It Is a natural phenomenon.  It's like our heart rate is high when we exercise, so here the mental exercise made the heart rate go up.  Not time they will give a medication to bring it down temporarily to get a good scan.  Now MRI will get us the anatomy of the heart.  If that is normal get a 24 holder or an event recorder depending on the frequency of your symptoms and that will check the electrical circuit of the heart which may cause the symptoms you describe, and both of these tests combined will rule out all possible cardiac cause of your symptoms.  Hoping I could help Regards Chat Doctor.
