Continuous hemodynamic monitoring in an intact rat model of simulated diving
Gaustad, Svein Erik; Kondratyev, Timofey; Eftedal, Ingrid; Tveita, Torkjel (Journal article; Peer reviewed, 2020)Cardiovascular risk is elevated in divers, but detailed information of cardiac function during diving is missing. The aim of this study was to apply an intact rat model with continuous monitoring of cardiac left ventricular ... -
Effects of cold decompression on hemodynamic function and DCS risk in a dry diving rat model
Gaustad, Svein Erik; Kondratyev, Timofey; Eftedal, Ingrid; Tveita, Torkjel (Peer reviewed; Journal article, 2021)Background: Diving in cold water is thought to increase the risk of decompression sickness (DCS), especially if the diver is cold during decompression. In this study, we investigated hemodynamic function and DCS risk in ... -
Resistance to ventricular fibrillation predicted by the QRS/QTc - ratio in an intact rat model of hypothermia/rewarming
Dietrichs, Erik Sveberg; Selli, Anders Lund; Kondratiev, Timofei; McGlynn, Karen; Smith, Godfrey L; Tveita, Torkjel (Peer reviewed; Journal article, 2021)Accidental hypothermia is associated with increased risk for arrhythmias. QRS/QTc is proposed as an ECG-marker, where decreasing values predict hypothermia-induced ventricular arrhythmias. If reliable it should also predict ... -
