Journal ArticleDOI

Measurement and interpretation of QT dispersion

Velislav N. Batchvarov, +1 more
- 01 Apr 2000 - 
TL;DR: It was shown that QT dispersion is not a direct reflection of the spatial variation of the recovery times and cannot be used for quantification of this variation, and inferences about the actual dispersion of the ventricular recovery times should not be made.
Journal ArticleDOI

Subject-specific heart rate dependency of electrocardiographic QT, PQ, and QRS intervals

Marek Malik, +3 more
- 01 Nov 2008 - 
TL;DR: Not only the heart rate dependency of QT interval but also the rate dependencies of PQ interval and of QRS width show high intrasubject stability with substantial intersubject differences.
Journal ArticleDOI

Hemodynamics and Autonomic Control of Heart Rate Turbulence

Dan Wichterle, +5 more
- 01 Mar 2006 - 
TL;DR: Late heart rate deceleration parallels the increase of systolic blood pressure during heart rate turbulence (HRT) after ventricular premature complexes (VPC), consistent with the involvement of baroreflex mechanism.
Journal ArticleDOI

Reflex and Tonic Autonomic Markers for Risk Stratification in Patients With Type 2 Diabetes Surviving Acute Myocardial Infarction

Petra Barthel, +7 more
- 01 Aug 2011 - 
TL;DR: Combined abnormalities of autonomic reflex function and autonomic tonic activity identifies diabetic postinfarction patients with very poor prognoses.
Journal ArticleDOI

Repolarization Abnormality for Prediction of All-Cause and Cardiovascular Mortality in American Indians: The Strong Heart Study

Peter M. Okin, +7 more
- 01 Sep 2005 - 
TL;DR: Analysis of electrocardiographic repolarization abnormality using QTc interval and principal component analysis (PCA) of the T‐wave vector predict all‐cause and cardiovascular mortality.
