Supports similar test performance in vasospastic angina; leaves open prospective validation before clinical adoption.
Does hyperventilation-thallium-201 myocardial scintigraphy have similar sensitivity and specificity to hyperventilation-electrocardiography in detecting vasospastic angina?
Hyperventilation-thallium-201 myocardial scintigraphy and hyperventilation-electrocardiography demonstrate comparable sensitivity and specificity for detecting vasospastic angina.
Falstie-Jensen et al. (1987) studied this question.
