Introduction: Repolarization dynamics, reflecting adaptation of QT to changing heart rate, is considered a marker of unfavorable prognosis in patients with heart diseases. We aimed to evaluate the prognostic value of QT/RR slope in predicting total mortality (TM) and sudden death (SD) in patients with congestive heart failure (CHF).

Heart Rate Turbulence as a Predictor of Cardiac Mortality and Arrhythmic Events in Patients with Dilated Cardiomyopathy: A Prospective Study
TLDR
The utility of HRT for risk stratification in patients with ischemic or nonischemic DCM, an autonomic predictor of mortality, is assessed.
Can QT/RR Relationship Differentiate between Low‐ and High‐Risk Patients with Hypertrophic Cardiomyopathy?
TLDR
Little is known about QT dynamics in hypertrophic cardiomyopathy (HCM), but normal dynamicity of repolarization is considered to be a marker of myocardial vulnerability contributing to increased risk of arrhythmic events and sudden death.
Risk stratification of mortality in patients with heart failure and left ventricular ejection fraction >35%.
Prognostic value of Holter monitoring in congestive heart failure.
TLDR
The present article reviews the literature data on the prognostic role of various Holter-based ECG parameters, with special emphasis to dynamic ECG risk markers--heart rate variability, heart rate turbulence, repolarization dynamics and variability--in predicting mortality, as well as different modes of death in patients with CHF.
High‐Risk Electrocardiographic Parameters are Ubiquitous in Patients with Ischemic Cardiomyopathy
TLDR
Although predictive accuracy might be improved among cohorts with a higher likelihood of cardiovascular events, this would also affect the prevalence of abnormal parameters and their exclusions.
Usefulness of heart rate turbulence for predicting cardiac events in patients with nonischemic dilated cardiomyopathy.
Role of Risk Stratifi cation After Myocardial Infarction
TLDR
Why risk assessment is needed and the methods available to facilitate risk assessment, the rationale for applying these techniques, and the limitations of these techniques are reviewed.
Electrocardiographic predictors of sudden and non-sudden cardiac death in patients with ischemic cardiomyopathy.
Diastolic heart failure: predictors of mortality.
TLDR
In patients with diastolic HF older age, male gender, non-Caucasian ethnicity, history of coronary artery disease and atrial fibrillation are associated with poor prognosis, and Anemia and B-type natriuretic peptide are significant laboratory variable that predict mortality.
Predictive Value of Beat-to-Beat QT Variability Index Across the Continuum of Left Ventricular Dysfunction: Competing Risks of Noncardiac or Cardiovascular Death and Sudden or Nonsudden Cardiac Death
TLDR
Increased QTVI because of depressed heart rate variability predicts cardiovascular mortality and non-SCD but neither SCD nor extracardiac mortality in heart failure across the continuum of left ventricular dysfunction.

A range of techniques for the assessment of autonomic tone are described, including baroreflex control of heart period, which is independently associated with adverse prognosis in patients with heart failure and following acute myocardial infarction.

TLDR
Patients with impaired left ventricular function have a high risk of developing ventricular arrhythmias and sudden death and there are limited data regarding feasibility of analyzing repolarization parameters and their dynamics in 24‐hour Holter ECG recordings.

TLDR
This work studied the relationship between QT and heart rate (RR interval) from ambulatory recordings using a novel method in patients with ischemic heart disease and varying degrees of left‐ventricular impairment (IHD) and compared them to healthy subjects (HS).
QT Dynamicity and Sudden Death After Myocardial Infarction:
TLDR
Whether impaired adaptation of the QT interval to changes in heart rate predicts sudden death after an acute myocardial infarction is investigated.

Predicting sudden death in patients with mild to moderate chronic heart failure
TLDR
Results show that an index derived from three widely available non-invasive investigations has the potential to identify ambulant patients with chronic heart failure at increased risk of sudden death.

TLDR
None of the QT or JT parameters were shown to be independent predictors of outcome in patients with mild to moderate congestive heart failure, and these variables do not therefore add to the prognostic information which can be gained from simple radiographic, biochemical, echocardiographic and Holter data.
