Symbiotic cardiac pacemaker

Nature Communications, 2019
Implantable medical electronic devices are limited by battery lifetime and inflexibility, but self-powered devices can harvest biomechanical energy. Here the authors demonstrate cardiac pacing and correction of sinus arrhythmia with a symbiotic cardiac ...

Identifying atrial arrhythmias versus pacing-induced rhythm disorders with state-of-the-art cardiac implanted devices

Journal of Arrhythmia, 2014
Repetitive non-reentrant ventriculo-atrial synchrony (RNRVAS) is a pacemaker-induced arrhythmia that must be distinguished from atrial fibrillation (AF). Pacemaker-induced arrhythmias are commonly detected as atrial high rate episodes (AHRE) by implanted

Asymptotics of conduction velocity restitution in models of electrical excitation in the heart [PDF]

, 2011
We extend a non-Tikhonov asymptotic embedding, proposed earlier, for calculation of conduction velocity restitution curves in ionic models of cardiac excitability.

Real‐world characteristics and treatment of cardiac transthyretin amyloidosis: A multicentre, observational study

ESC Heart Failure, Volume 12, Issue 2, Page 1203-1216, April 2025.
The 366 patients diagnosed with transthyretin amyloidosis cardiomyopathy (ATTR‐CM) were analyzed regarding their clinical characteristics in the first year after approval of tafamidis 61 mg for ATTR‐CM in Germany. Nearly two‐thirds of the patients were in an advanced disease stage and 64% met the key criteria of the “Transthyretin Amyloidosis ...

eGFR slope as predictor of mortality in heart failure patients

ESC Heart Failure, Volume 12, Issue 2, Page 1217-1226, April 2025.
Abstract Aims Heart failure (HF) leads to an imbalance between heart and kidney function, resulting in poor outcomes. However, the prognostic significance of the estimated glomerular filtration rate (eGFR) trajectory in HF patients remains unclear. We analysed electronic health records (EHRs) of real‐world HF patients, assessing eGFR trajectories and ...

Prognostic role of TAPSE to PASP ratio in outpatients with left ventricular systolic dysfunction

ESC Heart Failure, Volume 12, Issue 2, Page 912-922, April 2025.
Abstract Aims Few data are available regarding the role of tricuspid annulus plane systolic excursion to pulmonary artery systolic pressure (TAPSE/PASP), a measurement of right ventricular to pulmonary artery coupling, in patients with chronic heart failure and left ventricular systolic dysfunction.
