| Abstract: | To study dispersions of QT and QTc(QTd,QTcd) in patients with left ventricular hypertrophy caused by pathologic factors \ Methods\ QTd and QTcd were measured in 30 patients with essential hypertension(EH) associated left ventricular hypertrophy(LVH),15 patients with hypertrophic cardiomyopathy(HCM),15 patients with isolated aortic stenosis(AS),and 30 normal subjects \ Results\ QTd and QTcd are significantly greater in group EH,HCM and AS than normal group(P<0 01),HCM and AS were greater than EH(P<0 05 and P<0 01,P<0 05 and P<0 01),no significantly different between HCM and AS \ Conclusion\ QTd and QTcd may be a marker of pathologic left ventricular hypertrophy |
