How to Auscultate Heart Sounds

Like all patient assessments, the assessment of the cardiovascular system and heart needs to be done in a systematic manner.

Developing a good technique for listening to the heart prevents key information from being missed, and helps the practitioner organize their thoughts and assessment of the heart.

Ideally you should listen to the heart with the stethoscope against the patient’s skin. This is especially important if you have a low quality stethoscope. After examining the patient’s chest you want to identify some key landmarks to help you identify where to place your stethoscope. This is where a strong base of anatomy comes in.
