Roof‐dependent atrial flutter with epicardial conduction pathway masked by left atrium posterior wall debulking ablation

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
The 3D map shows a scarred area in the left atrial posterior wall. The left atrial posterior area and mitral isthmus line act as obstructions in the tachycardia. Propagation apparently shows a centrifugal pattern from LA inferoseptal area (yellow arrows).

A Novel Mathematical/Numerical Formula for Assessing Right Ventricular Torsion Using Echocardiographic Imaging [PDF]

arXiv, 2015
Recently, the ventricular torsional parameters have received special attention because of their significant role in the ventricular systolic and diastolic function. Right ventricular (RV) rotational deformation is a sensitive index for RV performance but difficult to measure.

Long‐term outcomes of electrical storm patients listed for urgent heart transplantation but not transplanted acutely

ESC Heart Failure, EarlyView.
Abstract Aims Refractory electrical storm (ES) is a life‐threatening condition in which heart transplantation (HTx) can be proposed. Nevertheless, the shortage of donors and subsequent outcomes question its place as a rescue strategy. We aim to describe the prognosis of ES patients listed for HTx but not transplanted.

Right subclavian vein approach for selective left bundle branch pacing: A case report

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
Imaging of pacing implantation process in the left bundle branch region of the right subclavian vein approach. Characteristics of left bundle branch capture during the screwring procedure using a novel connecting cable. Abstract We reported a 65‐year‐old man with symptomatic bradycardia caused by chronic atrial fibrillation who underwent pacemaker ...

His Bundle Pacing: Rebirth of an Important Technique for Pacing the Intrinsic Conduction System

Cardiovascular Innovations and Applications, 2018
Permanent pacemaker implant is a commonly performed cardiac procedure for treatment of bradycardia or conduction system abnormality. With conventional right ventricular (RV) pacing a lead is implanted at the RV apex or on the RV septum.

ECG beats classification using waveform similarity and RR interval [PDF]

arXiv, 2011
This paper present an electrocardiogram (ECG) beat classification method based on waveform similarity and RR interval. The purpose of the method is to classify six types of heart beats (normal beat, atrial premature beat, paced beat, premature ventricular beat, left bundle branch block beat and right bundle branch block beat).

The effects of inhomogeneities on scroll-wave dynamics in an anatomically realistic mathematical model for canine ventricular tissue [PDF]

arXiv, 2020
Ventricular tachycardia (VT) and ventricular fibrillation (VF) are lethal rhythm disorders, which are associated with the occurrence of abnormal electrical scroll waves in the heart. Given the technical limitations of imaging and probing, the in situ visualization of these waves inside cardiac tissue remains a challenge.

Transcoronary study of biomarkers in patients with heart failure: Insights into intracardiac production

ESC Heart Failure, EarlyView.
Abstract Aims Biomarkers are pivotal in the management of heart failure (HF); however, their lack of cardiac specificity could limit clinical utility. This study aimed to investigate the transcoronary changes and intracardiac production of these biomarkers.

The influence of sex on early post‐operative atrial fibrillation after cardiac surgery

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
Post‐operative atrial fibrillation characteristics were compared between 30 male patients matched with 30 female patients that were admitted for cardiac surgery. Patients were monitored continuously for a maximum of 5 days. This cover has been designed using resources from Flaticon.com Abstract Background Early post‐operative atrial fibrillation (EPOAF)

Effects of Cardiac Resynchronization Therapy on the Arrhythmic Substrate in a Patient with Long QT and Torsades de pointes

Journal of Arrhythmia, 2011
We describe a patient with torsades de pointes (TdP) who was implanted with cardiac resynchronization therapy defibrillator (CRT-D). At the time of CRT-D implantation, left ventricular (LV) epicardial pacing exacerbated TdPs and developed into electrical
