Continuous Electrocardiographic Recordings and Serial Changes of Various Serum Enzymes in a Patient With Variant Form of Angina Pectoris

A patient with a variant form of angina pectoris was subjected to continuous electrocardiographic recordings. This case was different from the variant form of angina pectoris as described by Prinzmetal et al., in that the ST segment elevation in the leads reflected the ischemic area during his chest pain, not only at rest, but also at the time of effort. With the cessation of pain, the ST segment rapidly returned to the appearance prior to the onset of an attack. This case also demonstrates the interesting serial changes of electrocardiograms taken by continuous electrocardiographic recordings during anginal attacks. The serial alteration of various serum enzymes in this case remained within the normal range except for the slightly transient increase of SCPK activity. In this case, practolol therapy was effective in alleviating the anginal attacks.
