EKG Machine

3 lead machines are designed to monitor the cardiac rhythm cycle, in 3 of the 12 primary leads. An attempt to use this limited information as a true diagnostic tool would be incomplete and perhaps misleading.

A full 12-lead machine is diagnostic, and looks at the elecrical information from all sides ("walls", ie anterior, septal, inferior, lateral, posterior) of the heart and gives detailed information regarding ischemia and or infarction of the cardiac muscle, electrical conduction system function, electrical axis, chamber enlargement, drug effects, and more.

Hope this helps.
