Abstract
Peripheral vascular disease is a marker of coronary artery disease, and QT dispersion (the difference between the longest and the shortest measurable interval on the 12 lead electrocardiogram) is emerging as an important marker of serious arrhythmias and sudden death. To link these two markers is not at first intuitive, but the common ground lies in the spectre of coronary artery disease. Darbar et al correlate peripheral vascular disease not just with any coronary artery disease but with the type that carries the highest risk of death. With a modest patient cohort (49) cardiac death was strongly correlated with the QTc dispersion. Values of > 60 ms had a 92% sensitivity and an 81% specificity in …Keywords
