QT dispersion may mark CAD extent in stable patients; leaves open its utility for risk stratification pending prospective studies.
Does the extent and severity of stable coronary artery disease correlate with increased rest QT dispersion and QT dispersion ratio in clinically stable subjects?
Rest corrected QT dispersion and QT dispersion ratio are increased and independently associated with the extent and severity of coronary atherosclerosis in patients with stable CAD.
