Reference 87, under the subheading of electrophysiology, cites the paper by Altschuler and associates (2) on the significance of isolated H-V (interval) prolongation in symptomatic patients without proven heart block. Your reviewer states, "Patients with central nervous system symptoms and H-V intervals > 60 ms were at high risk of early sudden death or progression to high-grade heart block. Mortality and morbidity were significantly reduced by pacemaker implantation." This statement is a serious misrepresentation of a very interesting study....References1. .
