Cardiac Sympathetic Nerve Sprouting and Susceptibility to Ventricular Arrhythmias after Myocardial Infarction

Figure 1

Anatomy and distribution of autonomic innervation of the heart. The cardiac parasympathetic nerves come from parasympathetic neurons located in the cardiac fat pads whose preganglionic fibers are carried within the vagus nerve. The cardiac sympathetic nerves come from the paravertebral ganglia and project from the base of the heart into the myocardium.
