Cardiac Resynchronization Therapy and AV Optimization: A Hemodynamic Evaluation with Non-Invasive Techniques

Düzce Tıp Fakültesi Dergisi
Aim: This study aimed to evaluate the impact of atrioventricular (AV) optimization of biventricular pacemakers on cardiac hemodynamic parameters, particularly mitral inflow and aortic valve velocity-time integral (VTI), using impedance cardiography (ICG)

Progression and prognostic significance of electrocardiographic findings in patients with cardiac amyloidosis

ESC Heart Failure, Volume 12, Issue 2, Page 809-818, April 2025.
Abstract Aims This study aimed to evaluate the change of the main electrocardiographic (ECG) characteristics and their prognostic role across the main subtypes of cardiac amyloidosis [light‐chain amyloidosis (AL) and hereditary (ATTRv) and wild‐type transthyretin amyloidosis (ATTRwt)].

Comparative outcomes of high-frequency pacing via a guidewire versus an endocardial electrode during transcatheter aortic valve implantation

Consilium Medicum
Background. Rapid ventricular pacing is routinely used during balloon aortic valvuloplasty and transcatheter aortic valve implantation (TAVI). Temporary right ventricular (RV) pacing via a temporary transvenous pacing lead is the standard approach ...

Myocardial threshold in patients with artificial pacemakers [PDF]

The American Journal of Cardiology, 1966
Abstract A method for estimating myocardial threshold in patients with implanted artificial pacemakers has been described. By the external application of a calibrated suppression signal, the output of the implanted unit can be gradually reduced until the myocardial response ceases. The threshold level thus determined can be expressed as a per cent of

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 ...

Modeling experiments on pacemaker interactions in scyphomedusae [PDF]

, 2009
Scyphozoan jellyfish are free-swimming gelatinous organisms whose nervous system includes a motor nerve net that controls swimming. Swim contractions originate in a network of distributed pacemakers found in the marginal rhopalia, which are located ...

Wireless Charger for Artificial Pacemaker [PDF]

, 2021
The vast majority of the modernized implantable devices and Bio-sensors are set inside a patient’s body. To overcome this constraint, in this paper we have designed a rechargeable battery with wireless power transfer technique. The transdermal power transfer for the Pacemaker which is placed inside the heart should be possible by the concept of mutual ...
