Clinically listening to the valves can give us an appreciation of the structure and functionality of each valve. Each valve hole corresponds to a specific point for listening. The fifth is Erbs point located left of the sternal border in the third intercostal space.
Heart auscultation points The emergence of tones as well as other sounds in the heart as mentioned above is primarily due to fluctuations in the valvular valves that are located between the atria and ventricles and between the ventricles and large vessels.
