0 any of the spaces inside the head that are connected to the back of the nose -- 竇，鼻竇

The electrocardiogram will confirm sinus bradycardia. 心電圖將證實竇性心動過緩。
In seven percent of the cases, the sinus nodal artery took origin from a separate orifice within the same sinus as a major coronary artery.
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.
