The prognostic value of exercise testing in elderly men.
PURPOSE Our purposes were to compare the responses to exercise testing in elderly (> or =65 years of age) and younger men, and to investigate whether exercise testing has similar prognostic value in the two age groups. METHODS We included all elderly (n = 1185) and younger (n = 2789) male veterans without established coronary heart disease who underwent routine clinical exercise testing betwe...
متن کاملDRUGS AND QTc INTERVAL DISPERSION
The measure of delayed ventricular repolarization most frequently used clinically is the ability of the new chemical entity to prolong the QTc interval on surface electrocardiogram. Intramyocardial dispersion of repolarization appears to play a more important role both in electrical stability of the ventricles and in arrhythmogenesis. The potential importance of myocardial dispersion of refract...
متن کاملPrognostic value of exercise testing.
We thank Dr Rønnevik for his comments on our article. Early works, such as the one published by Rønnevik and Von der Lippe are very valuable because they alert us to the real value of exercise testing. One of the main conclusions of the study of Rønnevik et al., namely that work capacity is associated with poor outcome in patients suspected of having myocardial infarction, fits well with our re...
متن کاملPotassium removal increases the QTc interval dispersion during hemodialysis.
This study was planned to clarify the mechanism(s) by which hemodialysis increases the QTc dispersion, a marker of risk of ventricular arrhythmias. To this aim, 10 uremic patients, without any relevant heart diseases, underwent two different types of hemodialysis schedules. In the first, 1 h of isolated high rate ultrafiltration preceded the standard diffusive procedure. In the second, during t...
متن کاملEffect of Average Annual Mean Serum Ferritin Levels on QTc Interval and QTc Dispersion in Beta-Thalassemia Major
Background There is evidence indicating impaired cardiomyocytic contractility, delayed electrical conduction and increased electrophysiological heterogeneities due to iron toxicity in beta-thalassemia major patients. In the present study, we compared the electrocardiographic and echocardiographic features of beta-thalassemia major patients with a healthy control group. Materials and Methods ...
