A cavernous sinus thrombosis, (a clot in the venous blood draining the face or sinuses and invariably fatal in pre-antibiotic days) should be considered. An electrocardiogram showed sinus rhythm with first degree atrioventricular block that advanced intermittently to second degree atrioventricular block. The sinus impulse is distributed through the plain working myocardium of the atrial walls to reach the atrioventricular junction. The widened coronary sinus itself never bulged into die left atrium. In our case, the only possible drainage for the left-sided atrium was through a window from the left atrium to the coronary sinus. The coronary sinus courses within the atrioventricular groove behind the left atrium to open into the right atrium. Only one patient had a sinus venosus defect in addition to the defect within the oval fossa. Accordingly, no different incidence of arrhythmias such as sick sinus syndrome, sinus bradycardia, junctional rhythm, or a wandering pacemaker should be expected. All measurements were performed under conditions of steady state, in sinus rhythm, and prior to angiography. The sinus extended through the tumour (?) to the peritoneal cavity. The sagittal sinus was cannulated through a coronary excision in the skull. In patients with large pericardial effusions, however, clear identification of the site of drainage of the coronary sinus was difficult. There was no evidence of impaired sinoatrial conduction, sinus nodal dysfunction or incomplete sinus node suppression during overdrive stimulation. This rotation moves the right coronary sinus leftwards and superiorly beneath the outlet septum, which misses its lower attachment.
