Nodal and infranodal atrioventricular conduction block: Electrophysiological basis to correlate the ECG findings

Indian Heart Journal, 2013
A 68-year-old woman with a history of dilated non-ischemic cardiomyopathy presented with syncope. The index ECG showed sinus rhythm with left bundle branch block.

Recurring patterns of atrial fibrillation in surface ECG predict restoration of sinus rhythm by catheter ablation [PDF]

, 2014
Background Non-invasive tools to help identify patients likely to benefit from catheter ablation (CA) of atrial fibrillation (AF) would facilitate personalised treatment planning.

Fetal arrhythmias: Diagnosis and management

Indian Pacing and Electrophysiology Journal, 2019
This article reviews important features for improving the diagnosis and management of fetal arrhythmias. The normal fetal heart rate ranges between 110 and 160 beats per minute.

Heart rate dynamics distinguish among atrial fibrillation, normal sinus rhythm and sinus rhythm with frequent ectopy

Physiological Measurement, 2015
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 ...

Left atrial minimal volume: association with diastolic dysfunction and heart failure in patients in sinus rhythm or atrial fibrillation with preserved ejection fraction

BMC Medical Imaging, 2021
Background Evidence of diastolic dysfunction (DD) required for the diagnosis of heart failure with preserved ejection fraction (HFpEF) is elusive in atrial fibrillation (AF).

Evaluation of left atrial and ventricular remodeling in atrial fibrillation subtype by using speckle tracking echocardiography

Frontiers in Cardiovascular Medicine, 2023
BackgroundAtrial fibrillation (AF) is associated with cardiac structural and functional remodeling. We investigated the left atrial (LA) and left ventricular (LV) changes in AF subtypes by using two-dimensional echocardiography strain techniques ...

Arrhythmia Classification from the Abductive Interpretation of Short Single-Lead ECG Records

, 2017
In this work we propose a new method for the rhythm classification of short single-lead ECG records, using a set of high-level and clinically meaningful features provided by the abductive interpretation of the records.

Cardioversion of atrial fibrillation does not affect obstructive sleep apnea

Upsala Journal of Medical Sciences, 2017
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.

Impact of atrial fibrillation on the cardiovascular system through a lumped-parameter approach [PDF]

, 2014
Atrial fibrillation (AF) is the most common arrhythmia affecting millions of people in the Western countries and, due to the widespread impact on the population and its medical relevance, is largely investigated in both clinical and bioengineering ...
