Normal ECG​

Answer 1

Answer:

The ECG is used to investigate suspected problems with the electrical conduction system of the heart as well as some other abnormalities such as metabolic disturbances (e.g. excess potassium). The ECG is an essential tool for health professionals in making a diagnosis of abnormal heart rhythms when one is suspected. It is a routine investigation in people who complain of symptoms such as chest pain as well as breathlessness. The findings of the ECG can also have an effect on treatment of certain conditions, for example it is helpful in deciding some aspects of treatment in people who have suffered from a heart attack.

Answer 2

Normal range 120 – 200 ms (3 – 5 small squares on ECG paper). QRS duration (measured from first deflection of QRS complex to end of QRS complex at isoelectric line). Normal range up to 120 ms (3 small squares on ECG paper).
