Answer

Bed rest is advisable for patients with new third-degree atrioventricular  (AV) block (complete heart block). Bed rest minimizes the chance of significant injury if syncope occurs as a result of ventricular asystole and decreases hemodynamic demand. A temporary pacemaker may be required.

Because these patients have decreased cardiac output, assuming an upright posture after prolonged periods in the supine position can lead to orthostatic hypotension with syncope or near-syncope.
