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.

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.

Electrocardiography in horses, part 1: how to make a good recording [PDF]

, 2010
Upon auscultation, cardiac dysrhythmias can be suspected, but electrocardiography is the ultimate diagnostic tool. Electrocardiogram (ECG) recording used to be reserved to specialized centers, but nowadays relatively cheap and small recorders are ...

Heart Rate Variability Features as Predictors of Intermittent Theta‐Burst Stimulation Response in Posttraumatic Stress Disorder

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Background Posttraumatic stress disorder (PTSD) is associated with autonomic dysfunction as indicated by deficits in the sympathetic and parasympathetic nervous systems. These abnormalities are expressed as elevated heart rate and reduced heart rate variability (HRV), respectively.
