Several studies have shown that a low frequency stimulation can depress blood pressure in hypertension. We had developed a new auriculoelectrostimulator as an electronic blood pressure regulator for simple and easy stimulation. The new auriculoelectrostimulator was employed in hypertensive rat model induced by immobilization stress, diabetic and essential hypertensive rat models. Rats were stimulated by auriculoelectrostimulator at ear acupoint (Ear point for hypertension) bilaterally. Ear stimulation by auriculoelectrostimulator significantly decreased blood pressure in all hypertensive rat models and inhibited the increase of heart rates in stressed and spontaneous hypertensive rats. The results showed that auriculoelectrostimulator had depressive effects on hypertension in rat hypertensive models, suggesting that it is useful in treatment of hypertension.
