Direct Sympathetic Heart Points
The bladder 11-15 points are extremely dangerous dim mak points because they can directly affect the heart. These points are located over the first five dorsal nerve roots, which are directly connected to the sympathetic nerves of the heart. Thus, attacking these points can stimulate the dorsal nerve roots and increase in the sympathetic stimulation of the heart. This is dangerous because increased sympathetic stimulation of the heart can cause ventricular fibrillation (fatal heart rhythm) or myocardial infarction (heart attack).
