Whilst the stress ECG will show past events, if any, and the present condition under stress, it does not predict the future. As my Cardiologist said to me, with a smile; "you could drop dead before you reach the exit, don't be complacent.", "It is not a guarantee." These tests are usually only prescribed as a result of identified signs or symptoms of the patient. The tests are expensive and probably would not be required if the CAA were paying the bill.
