The diagnostic accuracy of proprietary smartwatch algorithms and the interpretability ECG tracings may differ between available models. We compared potential for detecting atrial fibrillation (AF) three commercially smartwatches.We performed a prospective, non-randomized, adjudicator-blinded clinical study 100 patients in AF sinus rhythm, with flutter were excluded. All underwent 4 recordings: conventional 12-lead ECG, Apple Watch Series 5®, Samsung Galaxy Active 3®, Withings Move ECG®...
Conventional right ventricular (RV) apex pacing can lead to adverse clinical outcome associated with asynchronous activation and reduced left (LV) pump function. We investigated what extent alternate RV (septum) LV (septum, apex) sites improve electric activation, mechanics, hemodynamic performance, efficiency over 4 months of pacing.After AV nodal ablation, mongrel dogs were randomized receive 16 weeks VDD at the apex, septum, or septum (transventricular septal approach). Electric maps...
Background— Studies in canine hearts with acute left bundle branch block (LBBB) showed that endocardial ventricular (LV) pacing improves the efficacy of cardiac resynchronization therapy (CRT) compared conventional epicardial LV pacing. The present study explores CRT more compromised and mechanisms such beneficial effects. Methods Results— Measurements were performed 22 dogs, 9 LBBB, 7 chronic LBBB combined infarction (embolization; plus myocardial infarction, concentric remodeling), 6 heart...
Several studies suggest that patients with ischemic cardiomyopathy benefit less from cardiac resynchronization therapy. In a novel animal model of dyssynchronous cardiomyopathy, we investigated the extent to which presence infarction influences short-term efficacy therapy.Experiments were performed in canine hearts left bundle branch block (LBBB, n=19) and chronic myocardial infarction, created by embolization anterior descending or circumflex arteries followed LBBB (LBBB+left [LADi; n=11]...
Simple conceptual ideas about cardiac resynchronization therapy assume that biventricular (BiV) pacing results in collision of right and left ventricular (LV) pacing-derived wavefronts. However, this concept is contradicted by the minor reduction QRS duration usually observed. We investigated electric mechanisms performing detailed mapping during extensive protocols dyssynchronous canine hearts.Studies were performed anesthetized dogs with acute bundle-branch block (LBBB, n=10) chronic LBBB...
Smartwatch electrocardiograms (ECGs) could facilitate the detection of sudden cardiac arrest (SCA)-associated abnormalities. We evaluated feasibility using smartwatch-derived ECGs for detecting SCA-associated abnormalities in young adults and its agreement with 12-lead ECGs.Twelve-lead Apple Watch were registered 155 healthy volunteers 67 patients aged 18-45 years diagnosis ECG signs long-QT syndrome (n = 10), Brugada 12), ventricular pre-excitation 19), hypertrophic cardiomyopathy (HCM, n...
Remote monitoring of pacemakers decreases patient complications and reduces public health expenses. The transmission passive real-time electrograms (EGM) has been shown to increase the diagnostic yield, but this may add work burden. Passive EGMs provide snapshots without adjustments, while active modify pacemaker settings temporarily encourage sensing pacing, potentially revealing issues such as undersensing, oversensing, or loss capture. added value compared EGM remains be shown. objective...
Smartwatches that support the recording of a single-lead electrocardiogram (ECG) are increasingly being used beyond wrist, by placement on ankle and chest. However, reliability frontal precordial ECGs other than lead I is unknown. This clinical validation study assessed an Apple Watch (AW) to obtain conventional leads as compared standard 12-lead in both subjects without known cardiac anomalies patients with underlying heart disease. In 200 (67% ECG anomalies), was performed, followed AW...
Background— The relative contribution of electromechanical synchronization and ventricular filling to the optimal hemodynamic effect in cardiac resynchronization therapy (CRT) during adjustment stimulation-timings is incompletely understood. We investigated whether CRT requires collision pacing-induced intrinsic activation waves left ventricle (LV). Methods Results— was performed dogs with chronic bundle–branch block (n=8) or atrioventricular (AV) (n=6) through atrial (A), right (RV) apex,...
Abstract Aims From a patient and health system perspective, managing worsening heart failure (WHF) as an outpatient has become priority. Remote management allows early detection of WHF, enabling timely intervention with the aim preventing hospitalization. The objective study was to evaluate feasibility safety remotely WHF events using multiparametric platform. Methods results All patients enrolled in remote programme Bordeaux University Hospital Telemedicine Center between 1 January 31...
