Examination of the HeartExamination of the HeartExamination of the HeartExamination of the Heart
In the present era of technological In the present era of technological advances, particularly in the various advances, particularly in the various imaging modalities, there is a growing imaging modalities, there is a growing conception among practicing physicians conception among practicing physicians in cardiovascular medicine that bedside in cardiovascular medicine that bedside physical examination is unnecessary and physical examination is unnecessary and does not provide useful information. does not provide useful information.
