  • Single, uniform, premature ventricular complexes (VPCs) do not usually cause hemodynamic compromise and are at a low risk for electrical instability. As long as the VPCs are infrequent, and the heart rate and blood pressure remain stable, no additional treatment is necessary
  • Higher grade arrhythmias such as ventricular tachycardia warrant immediate medical intervention.
  • Accelerated idioventricular Rhythm (AIVR) is commonly seen in patients in the 24 hours following a splenectomy or surgery for gastric dilatation and volvulus. Accelerated idioventricular rhythms are identified as abnormal, wide, and bizarre beats that do not come prematurely. It is important to differentiate AIVR from ventricular tachycardia, because AIVR does not typically cause hemodynamic compromise and won’t respond to anti-arrhythmic medications. If AIVR is identified the procedure does not need to be stopped.
Dr Vet. Robert Trujanovic was born in Belgrade in 1990 and studied at the Faculty of Veterinary Medicine in Belgrade, where he graduated in veterinary medicine in 2015. He moved to Vienna in 2015 to start his position as assistant doctor in anesthesiology at the University of Veterinary Medicine Vienna, and later, he completed his internship there from 2017-2018. During this time, his interest in veterinary anesthesia deepened further and he started a residency at the Vetmeduni Vienna in 2018, which has been completed in 2021.


Throughout his time at the university, he has been heavily involved in research and teaching. Working on studies and passing on knowledge to students and colleges is especially important to him, as he finds that this is the only way to improve veterinary medicine. By working with simulators, he teaches students theoretical knowledge easily and quickly so that they can master later challenges quickly and efficiently. In addition, he is a passionate regional anaesthetist, passing on his knowledge through the latest learning methods. Inspired by these developments in veterinary regional anaesthesia and the huge popularity of it, he led a team of experts in veterinary medicine and have invested a great deal of passion into creating the first mobile app - the Vet RA App - focused on the most commonly used nerve blocks in small animals. Furthermore, he is very interested in cardiology, where he also continuously educates himself and applies and passes on his knowledge in the daily clinical routine. In addition, he is active as a speaker at various training events.
