According to the author, this monograph is a synthesis of the medical thinking at the Brigham Hospital on left ventricular failure, shock and hypotension, chest pain and coronary emergencies, pulmonary infarction and cor pulmonale, refractory congestive failure, electrolyte disturbances, digitalis intoxication, paroxysmal atrial tachycardia, atrial flutter, atrial tachycardia, atrial fibrillation, paroxysmal ventricular tachycardia, Adams-Stokes disease, syncope, cardiac arrest and resuscitation, and miscellaneous emergencies. It covers more than the emergencies, however. It is written primarily for the internist, general practitioner, and medical intern. The monograph is weak in its description of the surgical aspects of cardiac emergencies. There is, for example, no reference to a fundamentally different concept which concerns generalized and localized anoxia in the heart. The author states that "a respectable proportion of Demerol addiction has its roots in the soil of refractory coronary insufficiency." It is scarcely believable that a scientist would prefer meperidine addiction to surgical operation.
