Inter‐atrial block as a predictor of adverse outcomes in patients with HFpEF
ESC Heart Failure, EarlyView.Abstract Aims Inter‐atrial block (IAB), a marker of electrical atrial dysfunction, is associated with an increased risk of atrial fibrillation (AF) and adverse events in various populations. The prognostic impact of IAB in heart failure (HF) with preserved ejection fraction (HFpEF) remains unknown.

Journal of Cardiovascular Electrophysiology, Volume 33, Issue 12, Page 2606-2613, December 2022., 2022 Abstract Introduction Atrioventricular (AV)‐node ablation (AVNA) is a common therapy option for rate control strategy of permanent atrial fibrillation (AF). We hypothesized that isolation of the AV nodal isolation (AVNI) is associated with a more frequent preservation of an adequate escape rhythm compared to AVNA.

Discrete Wavelet Transform Based Algorithm for Recognition of QRS Complexes [PDF]
World of Computer Science and Information Technology Journal
(WCSIT) ; ISSN: 2221-0741; Vol. 4, No. 9, 127-132, 2014, 2017 This paper proposes the application of Discrete Wavelet Transform (DWT) to detect the QRS (ECG is characterized by a recurrent wave sequence of P, QRS and T-wave) of an electrocardiogram (ECG) signal. Wavelet Transform provides localization in both time and frequency.

Application of the Hidden Markov Model for determining PQRST complexes in electrocardiograms [PDF]
arXiv, 2020 The application of the hidden Markov model with various parameters in the segmentation task of QRS, ST, T, P, PQ, ISO complexes of electrocardiograms is considered. Models were trained using the Viterbi algorithm using the QT Database. For comparison, the Pan-Tompkins algorithm for searching for the duration of QRS complexes was modified.

ESC Heart Failure, EarlyView.Abstract Aims Cardiac resynchronization therapy (CRT) is guideline recommended for the treatment of symptomatic heart failure (HF) with reduced left ventricular ejection fraction and prolonged QRS. However, patients with common comorbidities, such as persistent/permanent atrial fibrillation (AF), are often under‐represented in clinical trials.

A FPGA system for QRS complex detection based on Integer Wavelet Transform [PDF]
, 2011 Due to complexity of their mathematical computation, many QRS detectors are implemented in software and cannot operate in real time. The paper presents a real-time hardware based solution for this task.
