A common diagnostic problem and a commonly misused drug.
Two common clinical problems are discussed, one diagnostic and one therapeutic. Chest pain, because of the possibility of cardiac origin, makes it an urgent diagnostic problem. Ischemic chest pain is considered from a diagnostic standpoint. Common causes of chest pain other than those of cardiac origin are considered. The objectives and basis of therapy for angina are briefly reviewed. Digitalis is discussed from the standpoint of its use and abuse. Digitalis intoxication is frequently overlooked, and it may be the cause of deterioration of the patient's cardiac status, rather than progression of the basic cardiac problem.
