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 ...

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.

Cardiac dysrhythmias after transcatheter closure of ASD with Amplatzer device

The Turkish Journal of Pediatrics, 2005
Transcatheter closure of atrial septal defect (ASD) has been used as an alternative to open heart surgery. Although transcatheter closure of ASD with the Amplatzer septal occluder is a safe and feasible method in pediatric patients, there is ...

An interesting electrocardiogram caused by lead reversal

BMC Cardiovascular Disorders
Background During normal sinus rhythm, atrial depolarization is conducted from right atrium to left atrium through Bachmann’s bundle, and a normal P wave axis which is measured on the frontal plane is between 0º and + 75º.

Antegrade and Retrograde Decremental Conduction Properties of an Accessory Pathway Associated with the Coronary Sinus Musculature

Indian Pacing and Electrophysiology Journal, 2015
A 32-year-old man underwent catheter ablation of an orthodromic atrioventricular reentrant tachycardia. The sinus rhythm electrocardiogram exhibited a normal PQ interval and no delta waves, but atrial pacing produced a prolonged PQ interval and wide QRS ...

Arrhythmic risk in elderly patients candidates to transcatheter aortic valve replacement. predicative role of repolarization temporal dispersion [PDF]

, 2019
Degenerative aortic valve stenosis (AS) is associated to ventricular arrhythmias and sudden cardiac death, as well as mental stress in specific patients. In such a context, substrate, autonomic imbalance as well as repolarization dispersion abnormalities ...

Exercise haemodynamics in pulmonary hypertension – a prospective pressure–volume loop study on right ventricular adaptation and prognosis

European Journal of Heart Failure, EarlyView.
Multimodal assessment during exercise distinguishes clinically relevant right ventricular (RV) adaptation patterns (homeometric and heterometric adaptation) in pulmonary hypertension. Disease controls are patients with invasive exclusion of pulmonary hypertension.
