Thank you for your query
The accuracy of the EKG depends on proper placement of the leads (on the chest), the surface on which the leads are attached (chest wall) and proper technique.

If everything is done right, then the EKG is the most reliable study of the electrical activity and conduction system of the heart. If done wrong, it could lead to conflicting conclusions.
An infarction is death of a tissue due to loss of blood supply. This then shows up as a hypokinetic area (echo) or an area of abnormal conduction (ekg).

Results of the investigations should be correlated with symptoms, your medical history and clinical findings to arrive at a diagnosis.
Hope this helps.
