THE EFFECTS OF GASTRIC AND HOMEOSTATIC AUTONOMIC AFFERENT REFLEXES ON CARDIAC AUTONOMIC EFFERENT ACTIVITY IN HEALTHY HUMAN VOLUNTEERS
… and sympathetic activity shown by increased QTc interval (mean 9.86 ± 8.59 msec increase, p< 0.05) during the first 40 minutes post-ingestion. These effects were absent with an identical volume of a physiological (0.9% w/v) saline solution which would increase plasma volume more, indicating …

Assessing the Relationship Between Electronic Medical Record (EMR) Generated QTc Alerts and Cancer Patient Mortality
BACKGROUND: EMR generated drug associated QTc alerts are generated frequently in cancer patient populations and in the last few years their annual frequency has outgrown the number of unique patient visits at our institution. Anecdotally, they are largely ignored by providers, contributing to …

Genetic Variants and Risk in Sudden Cardiac Death Syndromes
… in patients with LQTS, independently of the QTc interval. 3) In patients with HCM, marked QTc prolongation was associated with an increased risk of SCD events, and the minor alleles of SNPs at the NOS1AP locus influenced QTc length but were not directly associated with SCD events. 4) In …

Performance optimisation through the use of compression garments and biosensors
… (UCGs), and non-compression garments (NCGs). QT intervals (QT), corrected of QT intervals (QTc) was demonstrated significant difference in UCGs compared with NCGs. The results of Experiment 2 indicated a significant difference between CGs and NCGs at the end of the running test and from 90 …

The Effects of Glucose Tolerance, Hypertension, and Race on Heart Rate Variability, QT Interval Duration, and Left Ventricular Hypertrophy in Overweight-Obese Adolescents
… of heart rate variability (HRV), QT corrected (QTc) Interval duration, and Cornell voltage measures for left ventricular hypertrophy (LVH) to body mass index (BMI), relative body mass index (RBMI), and blood pressure (BP) measures, and to examine the effects of impaired glucose tolerance (IGT), …

The Pattern of Ventricular Repolarization during Therapeutic Hypothermia
… known to cause prolongation of the corrected QT interval (QTc). QTc prolongation can cause polymorphic ventricular tachycardia (VT) and ventricular fibrillation (VF). The interval from the peak to the end of the T wave (TpTe) indicates myocardial transmural dispersion of repolarization (TDR) and …

Athletes heart and exercise related sudden cardiac death: Across the age span
… of Long QT syndrome. Three athletes had a QTc value of >500 ms and all exhibited one of: paradoxical prolongation of QTc during exercise, a confirmatory genetic mutation, or prolonged QTc in a first-degree relative. In contrast, none of the athletes with a QTc value of <500 ms had any other …
