Different lead locations guided by fluoroscopy and ECG parameters and their effect on patients functional status

The Egyptian Heart Journal, 2019
Background Right ventricular apical pacing with the resultant left ventricular dyssynchrony often leads to depressed systolic function and heart failure.

Trend extraction in functional data of R and T waves amplitudes of exercise electrocardiogram

, 2016
The R and T waves amplitudes of the electrocardiogram recorded during the exercise test undergo strong modifications in response to stress. We analyze the time series of these amplitudes in a group of normal subjects in the framework of functional data ...

Analysis of Abnormal Intra-QRS Potentials in Signal-Averaged Electrocardiograms Using a Radial Basis Function Neural Network

Sensors, 2016
Abnormal intra-QRS potentials (AIQPs) are commonly observed in patients at high risk for ventricular tachycardia. We present a method for approximating a measured QRS complex using a non-linear neural network with all radial basis functions having the ...

Correlation of pacing site in right ventricle with paced QRS complex duration

Indian Pacing and Electrophysiology Journal, 2018
Background: Pacing from RV mid septum and outflow tract septum has been proposed as a more physiological site of pacing and narrower paced QRS complex duration.

Clustering in dilated cardiomyopathy at initial evaluation: An effective tool for clinical stratification

European Journal of Heart Failure, EarlyView.
Visual description of study design and main results. BBB, bundle branch block; ECG, electrocardiogram; MVA, major ventricular arrhythmia; SCD, sudden cardiac death. Abstract Aims Dilated cardiomyopathy (DCM) has a highly variable presentation and disease course. Current stratification strategies are complex and require multimodality evaluation.

Ablation of unmappable ventricular parasystole originating from the right ventricular outflow tract: a case report

BMC Cardiovascular Disorders, 2019
Background When the coupling interval is matched, ventricular parasystole can form a stable fusion QRS complex with sinus rhythm. Ablation of a fusion QRS complex has been rarely reported and is unexpectedly difficult.
