American physicians have been the poorer for their lack of acquaintance with much of the newer foreign work. This new book by an internationally distinguished cardiologist summarizes in flawless English his valuable contributions, which have been known, in the United States at least, only to connoisseurs. Although Dr Simonyi has used fairly sophisticated instruments and statistics to prove his methods, the information is derived from essentially simple carotid pulse curve derivatives, which could be recorded even on an office ECG. The text briefly explains his methods and demonstrates the practical versatility of the carotid derivative in diagnosing cardiac lesions like aortic valve disease, congestive heart failure, and hypertension and in measuring systolic time intervals and responses to physiologic challenges like exercise and pharmacologic challenges like catecholamine stimulation and propranolol blockade of β-adrenergic responses. This is a solid contribution to the theory and practice of noninvasive cardiology.
