Overview

Lev's disease is an acquired complete heart block due to idiopathic fibrosis and calcification of the electrical conduction system of the heart. Lev's disease is most commonly seen in the elderly, and is often described as senile degeneration of the conduction system.

One form has been associated with SCN5A.^[1]

Historical Perspective

It was described independently by two researchers in 1964,^[2]^[3] but the condition is generally called after Lev.

Pathophysiology

Associated Conditions

Stokes-Adams attacks can be precipitated by this condition. These involve a temporary loss of consciousness due to ventricular fibrillation or asystole.^[4]
