M. Gabriel Khan, MD, concisely assembles in a reader friendly format all the clinically useful information that an internist needs in both his daily rounds and abusy office practice to find correct clinical diagnoses and choose optimal pharmacologic therapies for their patients. Highlights include a simplified method for recognition of, and a practical therapeutic approach to, arrhythmias, as well as a more logical approach to drug management of hypertension than that given by the Joint National Committee, instructive algorithms that simplify the diagnosis and treatment of syncope, and extensive diagnostic information on hypertrophic cardiomyopathy. A large number of illustrative electrocardiograms that help to clarify the most often misinterpreted of all cardiologic tests and extensive discussions of practical cardiovascular pharmacology complete this magisterial survey.
