The Bezold-Jarisch reflex in a patient with coronary spastic angina.
2020
Acute inferior myocardial damage can induce transient bradycardia and hypotension-the Bezold-Jarisch reflex, which is explained by the preferential distribution of vagal nerves in the inferior wall of the left ventricle. We report a 76-year-old man who showed a perfusion defect in the inferior wall with redistribution on exercise scintigraphy with thallium-201. Of note, during exercise at an intensity of 100 watts, the patient's heart rate transiently decreased from 122 to 95 bpm in sinus rhythm, accompanied by ST-segment depression. A diagnosis of coronary spastic angina was made since no stenotic lesions were observed on conventional coronary angiography.
