No you can't read the EKG yourself. It takes special training to read EKG's. The doctor will read your EKG and tell you the results. An EKG detects and records the electrical activity of the heart. It also detects cardiac arrhythmias. It guides therapy and risk stratification for patients with suspected acute myocardial infarction
It helps detect electrolyte disturbances (e.g. hyperkalemia
and hypokalemia) It allows for the detection of conduction abnormalities (e.g. right and left bundle branch block
It is used as a screening tool for ischemic heart disease
during a cardiac stress test. It is occasionally helpful with non-cardiac diseases (e.g. pulmonary embolism
The electrocardiogram does not directly assess the contractility of the heart. However, it can give a rough indication of increased or decreased contractility.
Your doctor I am sure will explain everything in detail to you. I have had many EKG's they only take a few minutes to be done and they are painless (as you are probably already aware).
Best wishes to you.
