    Ergometrine-provoked coronary vasospasm on angiography without angina or ischaemia on ECG : a case report
    (Health & Medical Publishing Group, 1984) Przybojewski, J. Z.; Ellis, G. C.
    A 32-year-old White man suffered a large transmural inferoposterior myocardial infarction (MI). Coronary vasospasm is strongly suspected of having caused this MI since the ergometrine maleate provocation test gave rise to severe coronary vasospasm resulting in total occlusion of the dominant right coronary artery, without angina or ECG or haemodynamic features of myocardial ischaemia. This is a most unusual response to ergometrine maleate. Possible explanations are suggested and the implications are briefly discussed.

    Holter monitoring at Tygerberg Hospital, 1979-1983 : an appraisal
    (Health & Medical Publishing Group, 1984) Ellis, G. C.; Przybojewski, J. Z.; Weymar, H. W.
    Over a period of 4 years Holter monitoring was performed on 607 patients in the Division of Cardiology at Tygerberg Hospital. Indications for monitoring were broadly grouped into four categories: (i) evaluation of symptoms suggestive of disorders of cardiac rhythm (210 patients); (ii) evaluation of arrhythmias associated with a specific underlying cardiac condition (139 patients): (iii) evaluation of a previously documented or suspected arrhythmia (233 patients); and (iv) miscellaneous reasons (25 patients). Findings are presented and aspects of Holter monitoring are discussed. Finally, some recommendations for improving the clinical value of our Holter analyses are made.

    Hypertrophic cardiomyopathy complicated by complete heart block : case report and review of the literature
    (Health and Medical Publishing Group -- HMPG, 1984-12) Przybojewski, J. Z.; Van der Walt, J. J.; Ellis, G. C.; Tiedt, F. A. C.
    A 48-year-old man with symptoms of presyncope and congestive cardiac failure had hypertrophic cardiomyopathy (HCM) without obstruction. Complete heart block (CHB), a rare complication of this disease, was preceded by complete left bundle-branch block. Right ventricular (RV) heart failure was a dominant clinical feature but improved dramatically after temporary transvenous RV pacing prompting the insertion of a permanent RV inhibited pacemaker. Repeated ventricular fibrillation was successfully controlled by amiodarone. This is the 7th case of HCM complicated by CHB reported in the literature, and the first in which RV endomyocardial biopsies were undertaken. Two other patients reported in the literature had RV inhibited permanent pacemakers implanted, and a further 2 had atrioventricular sequential pacemakers.
