The ST 9 Point

The stomach 9 point is located directly over the carotid sinus, and the bifurcation of the carotid arteries. Over stimulation of the carotid sinus is associated with both cardiac arrest and  vasovagal fainting. Thus, attacking this point can stimulate the carotid sinus leading to a knockout or cardiac arrest. In addition, the carotid artery bifurcation is where the greatest buildup of artherosclerotic plaque occurs. Because of this, striking this area can cause a piece of plaque to break off and travel to the brain resulting in a stroke. Furthermore, blunt trauma to this area has been extensively discussed in the medical literature and there are many cases of blunt trauma causing a stroke, neurological deficits, and/or death. Interestingly, these effects can be instant or delayed. In fact, up to 80% of blunt carotid artery trauma results in delayed neurological impairment. The scary part is that these effects can occur up to ten years later.
