I had heart palpitations and the doctor put his finger somewhere on my neck and made it stop?  Do you know where on the neck he touched me
<|assistant|>
Yes, he likely touched you on the carotid sinus which is located on the side of the neck just below the angle of the jaw. It is the area where the artery up from the throat dives behind the ear and is sensitive to pressure. Stimulation of the carotid sinus can affect heart rate and cause heart palpitations.
