Apoplexy of the heart can be responsible for sudden and for recurring
instability of cardiac rhythm and conduction, and for the clinical
counterparts of syncope and sudden death. Every pathophysiological
mechanism which produces cerebral apoplexy has its counterpart in apoplexy
of the heart. Among the mechanisms documented are thrombosis, embolism and
rupture of those special vessels supplying the sinus node, atrioventicular
(A-V) node and His bundle. Apoplexy of the heart can occur either with or
without significant or recognizable ventricular myocardial infarction.
Acute vascular accidents within the critical centers of cardiac impulse
formation and conduction deserve more frequent consideration in the
explanation of unusual cases of "epilepsy", of seizure disorders of the
elderly, of neurologic manifestations (which may be secondary as well as
primary) of systemic diseases such as lupus erythematosus or thrombotic
thrombocytopenic purpura, and indeed of every case of otherwise
unexplanined syncope or sudded death at any age.
