Relationship between Mathematical Parameters of Modified Van der Pol Oscillator Model and ECG Morphological Features [PDF]
, 2019 The mathematical model describes the electrical and mechanical activity of the cardiac conduction system thought set of differential equations. By changing the value of parameters included in these equations, it is possible to change the amplitude and ...

Advanced Engineering Materials, EarlyView.Integrity constraints enforce consistency and completeness on data. The article discusses a newly developed validator for checking integrity constraints in Shapes Constraint Language (SHACL) through reduction to SPARQL Protocol and RDF Query Language (SPARQL) queries. It can be used with systems for ontology‐based database access.

A human in vitro platform for the evaluation of pharmacology strategies in cardiac ischemia
APL Bioengineering, 2019 Cardiac ischemic events increase the risk for arrhythmia, heart attack, heart failure, and death and are the leading mortality condition globally. Reperfusion therapy is the first line of treatment for this condition, and although it significantly ...

The Role of Notch Signaling on Heart Rate and Atrial Conduction [PDF]
, 2016 Heart disease is the leading cause of death worldwide and can result in arrhythmias, or dysregulation in the electrical activation of the heart. Sick Sinus Syndrome (SSS) is characterized by sinus bradycardia (slowed heart rate, HR), slowed conduction ...

Intracardiac electrophysiological conduction parameters in adult dogs
Veterinary Quarterly, 2017 Background: Invasive electrophysiology study (EPS) is one of the most important adjunct tests for the evaluation of arrhythmias in human medicine. However, EPS is neither well known nor widely used in veterinary medicine.

A Smart Cushion for Real-Time Heart Rate Monitoring [PDF]
, 2014 This paper presents a smart cushion for real time heart rate monitoring. The cushion comprises of an integrated micro-bending fiber sensor, which records the BCG (Ballistocardiogram) signal without direct skin-electrode contact, and an optical transceiver that does signal amplification, digitization, and pre-filtering.

Internal convection in thermoelectric generator models [PDF]
J. Phys.: Conf. Ser. 395, 012103 (2012), 2012 Coupling between heat and electrical currents is at the heart of thermoelectric processes. From a thermal viewpoint this may be seen as an additional thermal flux linked to the appearance of electrical current in a given thermoelectric system. Since this additional flux is associated to the global displacement of charge carriers in the system, it can ...
