Key result
Carotid sinus pressure observed to slow ventricular parasystolic foci and alter impulse formation.
Why the study?
Does carotid sinus pressure influence ectopic automatic ventricular impulse formation in man?
Does carotid sinus pressure influence ectopic automatic ventricular impulse formation in man?
This report provides evidence that carotid sinus pressure can influence ectopic automatic ventricular impulse formation in humans.
May modulate ventricular parasystole via vagal input; hypothesis-generating case report that leaves generalizability open.
No proof exists that carotid sinus pressure influences ectopic automatic ventricular impulse formation in man. Two patients are described who revealed during carotid pressure slowing of a ventricular parasystolic focus and a change of the area of impulse formation respectively.

Golbey et al. (1954) studied this question. Carotid sinus pressure slowed a ventricular parasystolic focus and changed the area of impulse formation in two patients.
