Early Repolarization and Arrhythmia Death
We appreciate the acknowledgement that the foreign gas rebreathing method is highly accurate for measuring the effective cardiac output (the blood flow to ventilated lung). This technique and its development are reviewed in great detail in an outstanding paper by Laszlo (5). Investigators at our institution, UT Southwestern, developed the most common modification of this technique, which made i...
متن کاملRole of Early Repolarization Pattern in Increasing Risk of Death.
BACKGROUND An early repolarization pattern (ERP) has been hypothesized to be arrhythmogenic in experimental studies, but the prognostic significance of the ERP in the general population is controversial. We performed a meta-analysis to examine the link between ERP and the risk of sudden cardiac arrest (SCA), cardiac death, and death from any cause. METHODS AND RESULTS We performed a literatur...
متن کاملHeart Rate and Risk of Cancer Death in Healthy Men
BACKGROUND Data from several previous studies examining heart-rate and cardiovascular risk have hinted at a possible relationship between heart-rate and non-cardiac mortality. We thus systematically examined the predictive value of heart-rate variables on the subsequent risk of death from cancer. METHODS In the Paris Prospective Study I, 6101 asymptomatic French working men aged 42 to 53 year...
متن کاملModeling and quantification of repolarization feature dependency on heart rate.
INTRODUCTION This article is part of the Focus Theme of Methods of Information in Medicine on "Biosignal Interpretation: Advanced Methods for Studying Cardiovascular and Respiratory Systems". OBJECTIVES This work aims at providing an efficient method to estimate the parameters of a non linear model including memory, previously proposed to characterize rate adaptation of repolarization indices...
متن کاملHeart rate variability and heart rate recovery as prognostic factors
BACKGROUND AND AIM Heart rate (HR) can appear static and regular at rest, during exercise or recovery after exercise. However, HR is constantly adjusted due to factors such as breathing, blood pressure control, thermoregulation and the renin-angiotensin system, leading to a more dynamic response that can be quantified using HRV (heart rate variability). HRV is defined as the deviation in time b...
