S. Ghaffar et Wa. Scott, Transient first-degree atrioventricular block following intercostal nerve block for vascular ring repair, PEDIAT CARD, 22(1), 2001, pp. 66-67
Transient first-degree heart block developed following surgery to divide a
vascular ring. This unusual complication was related to autonomic impairmen
t secondary to a local nerve block. The role of the autonomic innervation o
