Syncope: Clinical Presentation of Bronchial Asthma



Syncope, first described by Hippocrates, can be differentiated into neurological, cardiac and non-cardiac in origin, and this differentiation is of prognostic significance. The cardiac causes of syncope, which can be structural, electrophysiological or infectious, have a relatively poor prognosis and are associated with ethnicity, geographic location and sudden cardiac death. In decreasing frequency, the cardiac causes are hypertrophic cardiomyopathy, anomalous coronary arteries, Marfan Syndrome and dilated cardiomyopathy. Electrophysiological causes include supraventricular causes, Wolf-Parkinson-White syndrome, ion channelopathies, long QT syndrome and Brugada syndrome. The index case with bronchial asthma presented with syncope. There is an increased morbidity and mortality of this specific group of patients, if undiagnosed and not optimally treated; hence the need for a high index of suspicion and early diagnosis, after exclusion of cardiac and more common neurological causes. This is the first documented case of syncope secondary to bronchial asthma in an Afro-Caribbean.
