This results in an increase in the pressure of the right atrium, which stimulates the atrial stretch receptors (low pressure receptor zones). These receptors in turn signal the medullary control centers to increase the heart rate (Tachycardia). Unusually, this tachycardia is mediated by increased sympathetic activity to the sinoatrial node (SAN) with no fall in parasympathetic activity. seven little words mar 26 2023
