Postprandial ST depression and blunted output response may signal ischemia in angina; leaves open diagnostic value of meal provocation testing.
Do meals affect the electrocardiogram and ballistocardiogram in patients with angina pectoris compared to normal controls?
Meals can induce ischemic electrocardiographic changes and reveal an inability to increase cardiac output in patients with angina, suggesting a potential method for evaluating cardiac function.
BERMAN et al. (1950) studied this question.
