ESC Heart Failure, Volume 12, Issue 2, Page 955-967, April 2025.Abstract Wild‐type transthyretin amyloid cardiomyopathy (ATTRwt‐CM) is a progressive and infiltrative cardiac disorder that may cause fatal consequences if left untreated. The estimated survival time from diagnosis is approximately 3–6 years. Because of the non‐specificity of initial symptom manifestation and insufficient awareness among treating ...

ESC Heart Failure, Volume 12, Issue 2, Page 888-899, April 2025.Abstract Aims Heart failure with preserved ejection fraction (HFpEF) continues to be an increasingly common health problem associated with a high mortality rate. Elevated levels of Growth differentiation factor‐15 (GDF15) and N‐terminal pro‐brain natriuretic peptide (NT‐proBNP) are reportedly associated with poor clinical outcomes in a broad range of ...

Clinical Medicine Insights: Case Reports, 2010 Vagal maneuvers cause increase in vagal tone, which has been shown to slow many types supraventricular tachycardia, such as atrial fibrillation (AF). However, the conversion of AF to sinus rhythm is usually not associated with vagal manuvers. Thus, AF is

Cardiovascular Ultrasound, 2018 Background Atrial fibrillation (AF) can occur even after the correction of mitral valve (MV) pathology in patients who have pre-operative sinus rhythm and undergo MV surgery.

RNAseq shows an all-pervasive day-night rhythm in the transcriptome of the pacemaker of the heart
Scientific Reports, 2021 Physiological systems vary in a day-night manner anticipating increased demand at a particular time. Heart is no exception. Cardiac output is primarily determined by heart rate and unsurprisingly this varies in a day-night manner and is higher during the

Pharmacological analysis of sinus rhythm.
Folia Pharmacologica Japonica, 1993 The SA nodal pacemaker activity is regulated dominantly by autonomic nervous elements, i.e., sympathetic and parasympathetic nervous factors. In addition, circulatory bioactive substances and physicochemical factors also modify changes in sinus rate. Exogenously applied substances exert their actions on sinus rate directly and/or indirectly.

Frequency Analysis of Atrial Fibrillation From the Surface Electrocardiogram [PDF]
, 2004 Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice. Neither the natural history of AF nor its response to therapy are sufficiently predictable by clinical and echocardiographic parameters.

Automatic Mode Switching in Atrial Fibrillation [PDF]
, 2005 Automatic mode switching (AMS) algorithms were designed to prevent tracking of atrial tachyarrhythmias (ATA) or other rapidly occurring signals sensed by atrial channels, thereby reducing the adverse hemodynamic and symptomatic consequences of a rapid ...

Artificial intelligence for heart rate variability analyzing with arrhythmias [PDF]
, 2019 Introduction. Existing standards of Heart Rate Variability (HRV) technology limit its use to sinus rhythm. A small number of extrasystoles is allowed, if the device used has special procedures for the detection and replacement of ectopic complexes ...
