Window to the heart: the value of a native and paced QRS duration. Current perspective and review

J Interv Card Electrophysiol. 2003 Dec;9(3):333-42. doi: 10.1023/a:1027487225415.

Abstract

Given the technological advances and reliance upon expensive testing for guiding therapy, it is surprising how an inexpensive, low tech electrocardiogram can provide a wealth of information pertaining to the underlying cardiovascular status of a patient. In this article we review the changes in hemodynamics, prognosis and guidance of therapeutic options associated with a prolonged QRS duration.
