It is vital for NPs and PAs to be highly skilled in EKG interpretation to correctly identify high-risk patients and to make appropriate clinical decisions. This reference book is the first to present a comprehensive, multifaceted approach to EKG interpretation, covering all major topics required for expertise in this area. Based on a physiologic approach that facilitates in-depth understanding, the text includes clinical scenarios that may be seen in practice, and firmly links the information found in the EKG printout to the patient's symptoms. It clearly presents the gamut of requisite topics.
