Automatic measurements of mitral annular motion indices
Grue, Jahn Frederik Noraas (Doctoral theses at NTNU;2020:4, Doctoral thesis, 2020) -
Automatic measurements of mitral annular plane systolic excursion and velocities to detect left ventricular dysfunction
Grue, Jahn Frederik; Storve, Sigurd; Dalen, Håvard; Salvesen, Øyvind; Mjølstad, Ole Christian; Samstad, Stein; Torp, Hans; Haugen, Bjørn Olav (Journal article; Peer reviewed, 2018)The purpose of the study described here was to evaluate an automatic algorithm for detection of left ventricular dysfunction, based on measurements of mitral annular motion indices from color tissue Doppler apical four-chamber ... -
Automatic quantification of left ventricular function by medical students using ultrasound
Grue, Jahn Frederik; Storve, Sigurd; Dalen, Håvard; Mjølstad, Ole Christian; Samstad, Stein; Eriksen-Volnes, Torfinn; Torp, Hans; Haugen, Bjørn Olav (Peer reviewed; Journal article, 2020)Background Automatic analyses of echocardiograms may support inexperienced users in quantifying left ventricular (LV) function. We have developed an algorithm for fully automatic measurements of mitral annular plane ... -
Causes of in-hospital cardiac arrest - Incidences and rate of recognition.
Bergum, Daniel; Nordseth, Trond; Mjølstad, Ole Christian; Skogvoll, Eirik; Haugen, Bjørn Olav (Journal article; Peer reviewed, 2014-02)Background and methods: Do emergency teams (ETs) consider the underlying causes of in-hospital cardiac arrest (IHCA) during advanced life support (ALS)? In a 4.5-year prospective observational study, an aetiology study ... -
Feasibility and accuracy of point-of-care pocket-size ultrasonography performed by medical students
Andersen, Garrett Newton; Viset, Annja Torlaug; Mjølstad, Ole Christian; Salvesen, Øyvind; Dalen, Håvard; Haugen, Bjørn Olav (Journal article; Peer reviewed, 2014)Background Point-of-care ultrasound performed by clinicians is a useful supplement in the treatment and assessment of patients. We aimed to investigate whether medical students with minimal training were able to successfully ... -
In-hospital Cardiac Arrest Causes, Recognition and Survival
Bergum, Daniel (Doctoral theses at NTNU;2016:99, Doctoral thesis, 2016)Hjertestans på sykehus – En studie av underliggende årsaker. Tre studier ligger til grunn for denne avhandlingen. I disse studiene har vi gransket årsakene til hjertestans som oppstår plutselig og uventet inne på sykehus. ... -
Real-time Standard View Classification in Transthoracic Echocardiography using Convolutional Neural Networks
Østvik, Andreas; Smistad, Erik; Aase, Svein Arne; Haugen, Bjørn Olav; Løvstakken, Lasse (Journal article; Peer reviewed, 2018)Transthoracic echocardiography examinations are usually performed according to a protocol comprising different probe postures providing standard views of the heart. These are used as a basis when assessing cardiac function, ...
