Second Heart Sound - Physiologically Split #1 G

Second Heart Sound - Physiologically Split #1

During normal breathing, the timing between the aortic and pulmonic components of the second heart sound varies. This causes the second heart sound to be split. Maximum splitting occurs at peak inspiration. In the example you are hearing the splitting of the second heart sound is 60 milliseconds at peak inspiration and zero splitting at peak expiration.
