Multi-nodal nano-actuator pacemaker for energy-efficient stimulation of cardiomyocytes
Lu, Pengfei; Veletic, Mladen; Laasmaa, Martin; Vendelin, Marko; Louch, William Edward; Halvorsen, Per Steinar; Bergsland, Jacob; Balasingham, Ilangko (Journal article; Peer reviewed, 2019)There is continuous interest in maximizing the longevity of implantable pacemakers, which are effective in remedying and managing patients with arrhythmic heart disease. This paper accordingly first proposes miniature ... -
Non-invasive waveform analysis for emergency triage via simulated hemorrhage: An experimental study using novel dynamic lower body negative pressure model
Nesaragi, Naimahmed; Høiseth, Lars Øivind; Qadir, Hemin Ali; Rosseland, Leiv Arne; Halvorsen, Per Steinar; Balasingham, Ilangko (Peer reviewed; Journal article, 2023)The extent to which advanced waveform analysis of non-invasive physiological signals can diagnose levels of hypovolemia remains insufficiently explored. The present study explores the discriminative ability of a deep ... -
On the performance of hierarchical temporal memory predictions of medical streams in real time
El-Ganainy, Noha O.; Balasingham, Ilangko; Halvorsen, Per Steinar; Rosseland, Leiv Arne (Journal article; Peer reviewed, 2019)Machine learning is widely used on stored data, recently it is developed to model real time streams. Applying machine learning on medical streams might lead to a breakthrough on emergency and critical care through online ... -
Open chest and pericardium facilitate transpulmonary passage of venous air emboli
Storm, Benjamin; Halvorsen, Per Steinar; Skulstad, Helge; Dybwik, Knut Gustav; Schjalm, Camilla; Christiansen, Dorte; Wisløff-Aase, Kristin; Fosse, Erik; Braaten, Tonje Bjørndal; Nielsen, Erik Waage; Mollnes, Tom Eirik (Peer reviewed; Journal article, 2021)Background Transpulmonary passage of air emboli can lead to fatal brain- and myocardial infarctions. We studied whether pigs with open chest and pericardium had a greater transpulmonary passage of venous air emboli than ... -
Reduced inflammatory response by transcatheter, as compared to surgical aortic valve replacement
Hauge, Karoline Kråkmo; Dahle, Gry; Bendz, Bjørn; Halvorsen, Per Steinar; Abdelnoor, Michael; Mollnes, Tom Eirik; Fosse, Erik (Journal article, 2017)Objectives. The inflammatory response to on-pump cardiac surgery is well known. Systemic inflammatory response syndrome after transcatheter valve implantation (TAVI) has been reported. The objective of this study was to ... -
Sepsis causes right ventricular myocardial inflammation independent of pulmonary hypertension in a porcine sepsis model
Pischke, Søren; Hestenes, Siv Merete; Johansen, Harald Thidemann; Fure, Hilde; Bugge, Jan F; Espinoza, Andreas Westenvik; Skulstad, Helge; Edvardsen, Thor; Fosse, Erik; Mollnes, Tom Eirik; Halvorsen, Per Steinar; Nielsen, Erik Waage (Journal article; Peer reviewed, 2019)Introduction Right ventricular (RV) myocardial dysfunction is a common feature in septic shock. It can worsen outcome, but the etiology is poorly understood. Pulmonary artery hypertension (PAH) plays a part in the ... -
