Laboratory of Biomeasurements The laboratory is part of the Department of Biomeasurements and the Department of Theoretical Methods. Its equipment is used in several projects focused mainly on the research of heart and brain activity. Most laboratory equipment is the result of in-house research and development.     ProCardio 8 is a 128-channel PC-based mobile…

Investigators: Anna Přibilová, Jana Švehlíková, Ján Zelinka, Milan Tyšler The study proposes parameters potentially suitable for optimal ventricular stimulation settings in cardiac resynchronization therapy. The parameters are determined from autocorrelation maps (ACM) calculated from surface potential maps of 17 patients, 14 of whom have left bundle branch block and three have right bundle branch block….

Investigators: Milan Tyšler, Richard Bagín, Daniel Gogola, Fedor Lehocki, Beáta Ondrušová An innovative system for monitoring the vital functions of injured persons during mass disasters was developed. The system features smart patches designed to record electrocardiograms, photoplethysmograms, respiratory movements, and body temperature from the chest of injured persons. The patches autonomously evaluate heart rate and…

Investigators: Švehlíková J., Ondrušová B., Zelinka J., Tyšler M., Hlivák P., Rasoolzadeh N., Serinagaoglu-Dogrusoz Y.S., The aim of the joint project of the IOM SAS and Middle East University in Ankara was to apply the inverse electrocardiography methods used at each site to the same data from multi-lead chest measurements. We applied the inverse methods…

Investigators: Beáta Ondrušová, Peter Tiňo, Jana Švehlíková This study addresses the non-invasive localization of cardiac abnormalities, specifically premature ventricular contractions (PVCs), through a newly proposed two-stage inversion solution for a dipole cardiac source. One of the inputs for solving the inversion problem is the surface potentials measured using a large number (128) of electrodes placed…

Investigators: Jana Švehlíková, Anna Přibilová, Ján Zelinka, Beáta Ondrušová, Katarína Kromková, Peter Hlivák, Robert Hatala, Milan Tyšler The input data for localization of the source of premature ventricular activity (PKA) were averaged ECG signals obtained from a 5-20 minute recording of multi-lead ECG measured in 14 patients diagnosed with PKA. During its standard processing, the…

Investigators: Lehocki F., Tyšler M., Gogola D., Bagín R., Madevska Bogdanova A., Koteska B., Spasenović M., Vićentić, T. et al. As part of the NATO project, sensors were designed and methods were developed for monitoring the vital functions of mass casualty victims using a wearable system. The proposed resistive sensors based on laser-deposited graphene layers…

Investigators: Beáta Ondrušová, Jana Švehlíková, Ján Zelinka, Milan Tyšler, Peter Tiňo   In the study, we proposed a methodology for determining the significance of signals from individual electrodes of multichannel ECG measurement for solving the inverse problem to locate the source of the ventricular extrasystole. This method is based on the singular decomposition of the…

Investigators: Bear L.R., Serinagaoglu Dogrusoz Y., Good W., Svehlikova J., Coll_Font J., van Dam E., MacLeod R. Within the consortium for electrocardiographic imaging, we investigated the effect of processing measured ECG signals on the chest surface on the inverse reconstruction of epicardial potentials and activation maps on the heart. Data were obtained from 4 animal…
