Sinus Bradycardia is a reference to the Sinus Node, the heart's own natural pacemaker.
Bradycardia is, as been pointed out, a pulse rate of less than 60.
Notwithstanding the fact it can be a indication of fitness, it can also be pointer to underlying malignant conditions, which is of course what they are looking for.
As regards the ECG, this can be regarded as a picture of the electrical activity of the heart and unfortunately has its limitations.It can show previous damage to the heart but may not detect even quite advanced heart disease.
Hope this helps.
PS Nurse can't be blamed in the slightest.Interpretation by a Cardiologist is quite detailed-that's why i costs extra at our medicals to have it read.They pay attention to the slightest changes- which if they exist can cause excitment at the Belgrano, and even more so for the poor unfortunate concerned.
Trust me, I'm not a Doctor
