Circulatory System

What clinical indicator is the nurse most likely to identify when completing a history and physical assessment of a client with a complete heart block?

ExplanationA. With complete atrioventricular block, the ventricles take over the pacemaker function in the heart but at a much slower rate than that of the SA node. As a result there is decreased cerebral circulation, causing syncope. B. Headache is not related to heart block. C. The heart rate usually is slow because the ventricular rhythm is not initiated by the SA node. D. This is not related to heart block unless decreased cerebral perfusion causes a brain attack.
