A reduced-order model based on proper orthogonal decomposition (POD) is proposed for the bidomain equations of cardiac electrophysiology. Its accuracy is assessed through electrocardiograms in various configurations, including myocardium infarctions and long-time simulations. We show in particular that a restitution curve can efficiently be approximated by this approach. The reduced-order model...

introduction: treatment of supraventricular arrhythmia includes wide range of medical interventions. herbal remedies are suitable alternatives for synthetic drugs due to their availability, minimal side effects and lower price. pharmacological studies and traditional medical literature point to the cardiovascular effects of the artemisia absinthium l. from compositae family of plants. methods: ...

background and aims: charcot marie tooth disease (cmt) is the most prevalent hereditary neuropathy and its frequency is 1 in 2500. cmt is a heterogeneous disease and has different clinical symptoms. the prevalence of cmt and involved genes differ in different countries. cmt patients experience considerable sleep problems and a higher risk of decreased quality of life. in this work it was aimed ...

objective considerable medical and legal debates have surrounded the prognosis and outcome of obstetrical brachial plexus injuries and obstetricians are often considered responsible for the injury. in this study, we assessed the factors related to the outcome of brachial plexus palsy. material & methods during 24 months, 21 neonates with obstetrical brachial plexus injuries were enrolled. elect...

Introduction: XMR systems are a new type of interventional facility in which patients can be rapidly transferred between x-ray and MR systems on a floating table. We have previously developed a technique to register MR and x-ray images obtained from such systems. We are carrying out a programme of XMR guided cardiac electrophysiology study (EPS) and radio frequency ablation (RFA). Aim: The aim ...

Electrophysiology, which is the study of electrical properties biological tissues and cells, has become indispensable in modern clinical research, diagnostics, disease monitoring therapeutics. In this paper we present a brief history discipline how integrated circuit design shaped electrophysiology last few decades. We will discuss biopotential amplifier evolved from classical three-opamp archi...
