A. The physician can confirm the attack by carefully studying the patient's history by physical examination; and by electrocardiogram, along with other laboratory investigations. It is important to emphasize the fact that in the first few hours or even days, when the patient is in a serious state, the electrocardiogram may show no deviation or only a slight deviation from the normal, yet the patient would need all the care given to a seriously ill person.

Q. How can it be confirmed that a patient has angina ?

A. This can be done by carefully taking a detailed history. Objective evidence is sought with the help of the electrocardiogram. ECG taken at rest, i.e., without exercise, may show some evidence, but, not infrequently it is within normal limits. The patient is then made to perform some exercise and the ECG is repeated to check if any changes of myocardial ischaemia have appeared.
