Short-term Heart Rate Turbulence Analysis Versus Variability and Baroreceptor Sensitivity in Patients With Dilated Cardiomyopathy [PDF]

open access: yes, 2004
New methods for the analysis of arrhythmias and their hemodynamic consequences have been applied in risk stratification, in particular to patients after myocardial infarction.

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

open access: yes, 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.

Mechanical and Electrical Phenotype of hiPSC‐Cardiomyocytes on Fibronectin‐Based Hydrogels

open access: yesAdvanced Healthcare Materials, EarlyView.
We introduce fibronectin‐based PEG hydrogels with controlled rigidity to enable the culture of iPSC‐derived cardiomyocytes. These substrates offer an alternative to the current culture of these cells on fibronectin‐coated glass, providing enhanced structural and functional behavior. The system provides a more physiologically relevant platform to assess

Prediction model and scoring system for the risk of atrial fibrillation recurrence in patients with atrial fibrillation and obstructive sleep apnoea syndrome: a retrospective case-control study

open access: yesBMC Cardiovascular Disorders
Background The high prevalence of atrial fibrillation (AF) and obstructive sleep apnea syndrome (OSAS) imposes a substantial disease burden on public healthcare, making it a significant health concern in the current era.

Modular Platform for Rapidly Investigating Long‐Distance Propagation of Human Neural Network Activity

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents the first human neural organoid culture model capable of rapidly exhibiting long‐distance neural network propagation, thus delivering a system to experimentally investigate large‐scale communication during normal and diseased states.

Automatic Mode Switching in Atrial Fibrillation [PDF]

open access: yes, 2005
Automatic mode switching (AMS) algorithms were designed to prevent tracking of atrial tachyarrhythmias (ATA) or other rapidly occurring signals sensed by atrial channels, thereby reducing the adverse hemodynamic and symptomatic consequences of a rapid ...
