Rate-dependent propagation of cardiac action potentials in a one-dimensional fiber [PDF]

, 2004
Action potential duration (APD) restitution, which relates APD to the preceding diastolic interval (DI), is a useful tool for predicting the onset of abnormal cardiac rhythms. However, it is known that different pacing protocols lead to different APD restitution curves (RCs).

Intra-Inter Subject Self-supervised Learning for Multivariate Cardiac Signals [PDF]

arXiv, 2021
Learning information-rich and generalizable representations effectively from unlabeled multivariate cardiac signals to identify abnormal heart rhythms (cardiac arrhythmias) is valuable in real-world clinical settings but often challenging due to its complex temporal dynamics.

Remote patient monitoring in heart failure: A comprehensive meta‐analysis of effective programme components for hospitalization and mortality reduction

European Journal of Heart Failure, EarlyView.
Remote patient monitoring in heart failure (HF). Abstract AimsMethods of non‐invasive remote patient monitoring (RPM) for heart failure (HF) remain diverse. Understanding factors that influence the effectiveness of RPM on HF‐related and all‐cause hospitalizations, mortality, and emergency department visits is crucial for developing successful RPM ...

Estimulação cardíaca artificial em pacientes portadores de cardiomiopatia hipertrófica: uma coorte com 24 anos de seguimento [PDF]

Arquivos Brasileiros de Cardiologia, 2008
The benefits of heart stimulation in hypertrophic cardiomyopathy (HCM) patients have been questioned. Research work available in Brazil on those benefits is scarce.To describe the indication, clinical response, complications and survival time related to pacemaker implant in HCM patients.Thirty-nine hypertrophic cardiomyopathy patients were studied (41%

Terminating ventricular tachycardia by pacing induced dynamical inhomogeneities in the reentry circuit [PDF]

arXiv, 2004
Formation of feedback loops of excitation waves (reentrant circuit) around non-conducting ventricular scar tissue is a common cause of lethal cardiac arrhythmias, such as ventricular tachycardia. This is typically treated by rapid stimulation from an implantable device (ICD). However, the mechanisms of reentry termination success and, more importantly,

Cardiac rhythm devices in heart failure with reduced ejection fraction – role, timing, and optimal use in contemporary practice. European Journal of Heart Failure expert consensus document

European Journal of Heart Failure, EarlyView.
Abstract Guidelines for management of heart failure with reduced ejection fraction (HFrEF) emphasize personalized care, patient engagement, and shared decision‐making. Medications and cardiac rhythm management (CRM) devices are recommended with a high level of evidence. However, there are significant disparities: patients who could benefit from devices

Long-Term Mortality in Cardioinhibitory Carotid Sinus Hypersensitivity Patient Cohort [PDF]

Arquivos Brasileiros de Cardiologia
Background: Cardioinhibitory carotid sinus hypersensitivity (CICSH) is defined as ventricular asystole ≥ 3 seconds in response to 5-10 seconds of carotid sinus massage (CSM). There is a common concern that a prolonged asystole episode could lead to death
