The Bezold–Jarisch reflex in a patient with coronary spastic angina

Figures

• 

  FIGURE 1. Electrocardiography shows horizontal ST‐segment depressions in leads II, III, aVF, and V4 to V6 at the peak of the exercise (a, right on each panel), compared with before exercise (a, left on each panel). The increase in blood pressure during the exercise test is not obvious (b); the double product decreases before the discontinuation of exercise (red vertical line). The heart rate transiently drops from 122 to 95 bpm (c, arrow) just before the peak of the exercise, along with an ST‐segment depression (d)

• 

  FIGURE 2. An electrocardiogram shows that the heart rate decreased from 116 to 101 bpm, followed by an increase to 121 bpm, approximately between 36 to 26 s (double‐headed arrow) before the discontinuation of exercise (dotted line). HR denotes heart rate, which was averaged according to the prior 30‐s interval

  FIGURE 3. After exercise with thallium‐201 exercise scintigraphy, the tracer uptake is decreased in the inferior wall of the left ventricle as determined by single‐photon emission computed tomography (a) and a bull's eye map (b), with complete redistribution of images obtained 3 hr later (c and d)
