@entity3361 can now be well documented in the cardiac catheterization laboratory. At present, reliable criteria are available for the diagnosis of severe episodes that are characteristic of @entity1 with @entity5135 . Newer criteria for the diagnosis of milder episodes of @entity2473 are gradually being developed. Optimal criteria may become available with further progress of quantitative angiography. Provocation techniques for the induction of an attack of @entity2473 in the cardiac catheterization laboratory are widely available. Of these, @entity3693 testing is the most popular. The tests can usually be performed by experienced angiographers with impressive safety and provide a high degree of sensitivity and specificity when used in @entity1 with the clinical diagnosis of @entity5968 . Although the research applications of such techniques are extremely broad, their practical clinical indications are somewhat limited to the work-up of @entity1 with infrequent @entity662 and normal or near-normal coronary arteriograms. There are other indirect methods for the diagnosis of @entity3361 , but the ideal technique is not available yet. Further expansion of newer modalities for the diagnosis of @entity3361 will certainly enhance our understanding of @entity741 and will improve our ability to manage @entity1 with @entity741 .

The diagnosis of XXXX in the cardiac catheterization laboratory.
