Chapter 10 The Cardiovascular Exam





A. Generalities


Cardiovascular examination is centered on five main components, all essential for making a diagnosis. This section discusses inspection, palpation, and percussion. Auscultation is addressed in two separate presentations.




B. General (Physical) Appearance



2 What aspects of general appearance should be observed in evaluating cardiac patients?


As suggested by Perloff, one should sequentially evaluate the following nine areas:



See Tables 10-1 and 10-2.

C. The Arterial Pulse




Evaluation of the arterial pulse is a time-honored method of bedside examination. It can still provide valuable cardiovascular information. In selective processes (such as tamponade, aortic valve disease, and hypertrophic cardiomyopathy), it can even prove essential for securing a diagnosis. Yet, assessment of the characteristics of the arterial pulse requires skill and practice, and at times can be frustrating. It is worth the effort, though, and thus deserves attention, even in our times of intra-arterial monitoring.

































33 What is the diagnostic significance of a pulsus bisferiens?


It usually reflects moderate to severe aortic regurgitation (with or without aortic stenosis), but can also occur in other high output states. In aortic regurgitation, however, the double pulse is not only palpable, but sometimes is even audible. For example, it can be detected as:
