Autonomic innervation on the heart The heart gets nerve indicators within the vagus nerve and from nerves arising in the sympathetic trunk. These nerves act to influence, but not Handle, the heart fee. Sympathetic nerves also impact the pressure of heart contraction.[33] Indicators that journey alongside these nerves come up from two paired cardiovascular centres from the medulla oblongata.
In some arrhythmias like atrial fibrillation which boost the danger of stroke, this danger may be decreased utilizing anticoagulants such as warfarin or novel oral anticoagulants.[sixty one]
