In this mentoring webinar, we will discuss the clinical use of heart rate variability biofeedback (HRVB) in working with development trauma and social anxiety. First, Dr. Khazan will present a brief protocol for heart rate variability biofeedback training that may be used in most situations where HRVB is helpful. Second, she will describe in detail the use of HRVB for the 2 clinical cases. Participants will have an opportunity to ask questions after each case.
