Background: Atrial flutter is a common arrhythmia in structurally normal or abnormal heart. The electrocardiographic features of it can be mistaken for sinus tachycardia or supraventricular tachycardia.

Atrial fibrillation (AF) is usually detected by inspection of the electrocardiogram waveform, a task made difficult when the signal is distorted by noise. The RR interval time series is more frequently available and accurate, yet linear and nonlinear time series analyses that detect highly varying and irregular AF are vulnerable to the common finding ...

A study on stability analysis of atrial repolarization variability using ARX model in sinus rhythm and atrial tachycardia ECGs [PDF]
© 2016 Elsevier Ireland Ltd Background The interaction between the PTa and PP interval dynamics from the surface ECG is seldom explained. Mathematical modeling of these intervals is of interest in finding the relationship between the heart rate and ...

Myocardial Architecture and Patient Variability in Clinical Patterns of Atrial Fibrillation [PDF]
Atrial fibrillation (AF) increases the risk of stroke by a factor of four to five and is the most common abnormal heart rhythm. The progression of AF with age, from short self-terminating episodes to persistence, varies between individuals and is poorly ...

Cardioversion of atrial fibrillation does not affect obstructive sleep apnea
Background: Sleep apnea is common in patients with atrial fibrillation, but the effect of the cardioversion of atrial fibrillation to sinus rhythm on central and obstructive apneas is mainly unknown.

Characteristics of the heart rhythm in children with gastroesophageal reflux disease
Background. Incidence of gastroesophageal reflux disease (GERD) increases in patients from different age groups throughout the world. Studying the extraesophageal manifestations, including cardiologic symptoms of GERD, in children is relevant.

Altered excitation-contraction coupling in human chronic atrial fibrillation [PDF]
This review focuses on the (mal)adaptive processes in atrial excitation-contraction coupling occurring in patients with chronic atrial fibrillation. Cellular remodeling includes shortening of the atrial action potential duration and effective refractory ...

Abstract Everything can be connected in the Internet of Things (IoTs) technology that enables efficient communication between connected objects. IoTs industry‐based meta‐heuristic and mining algorithms, which are considered an important field of Artificial Intelligence will be used to construct a healthcare application in this study for lowering costs,

The effects of repetitive electric cardiac stimulation in dogs with normal hearts, complete heart block and experimental cardiac arrest [PDF]
Direct cardiac stimulation was conducted in the open chest. In normal animals, auricular stimulation at frequencies faster than the spontaneous rate caused little change in vascular pressures or cardiac output.
