Simultaneous mapping of endocardium and epicardium from multielectrode intrachamber and intravenous catheters: a computer simulation-based validation.

• Engin Baysoy, Ugur Cunedioglu, Bülent Yilmaz
• Journal of electrocardiology
• 2010

A multielectrode basket-shaped contact catheter (MBC) provides simultaneous recordings of unipolar or bipolar electrograms from within the heart chambers. Another catheter-based mapping approach uses… (More)

Usage of statistical estimation method for the simultaneous mapping of inner and outer surfaces of the heart

• Ugur Cunedioglu, Engin Baysoy, Bulent Yilmaz
• 2009 14th National Biomedical Engineering Meeting
• 2009

To characterize the cardiac rhythm disturbances catheter-based cardiac mapping approaches have become a common practice due to their minimal invasiveness. A multielectrode basket-shaped contact… (More)

Feasibility of probabilistic neural networks, Kohonen self-organizing maps and fuzzy clustering for source localization of ventricular focal arrhythmias from intravenous catheter measurements

• Ahmet Sertaç Sunay, Ugur Cunedioglu, Bülent Yilmaz
• Expert Systems
• 2009

An important goal of clinical electrophysiological studies is estimation of the source of rhythm disturbances (arrhythmia) in the heart. 15% of ventricular arrhythmias are known to originate from the… (More)

Novel spatial interpolation methods for catheter-based mapping of endocardial arrhythmias

• Engin Baysoy, Ugur Cunedioglu, Bulent Yilmaz
• 2009 IEEE 17th Signal Processing and…
• 2009

Due to their minimal invasiveness catheters are highly prefered as cardiac mapping techniques used in the source localization of rhythm disturbances in the heart (arrhythmias). It is known that most… (More)

Combination of Computer Simulations and Experimental Measurements as the Training Dataset for Statistical Estimation of Epicardial Activation Maps From Venous Catheter Recordings

• Ugur Cunedioglu, Bülent Yilmaz
• IEEE Transactions on Biomedical Engineering
• 2009

One of the epicardial mapping techniques requires the insertion of multiple multi-electrode catheters into the coronary vessels. The recordings from the intracoronary catheters reflect the electrical… (More)

Source localization of focal ventricular arrhythmias using linear estimation, correlation, and back propagation networks

• Bülent Yilmaz, Ugur Cunedioglu
• Comp. in Bio. and Med.
• 2007

Catheter-based approaches used in the localization and treatment of the source of heart rhythm disturbances (arrhythmias) have become popular, because they do not require highly invasive and risky… (More)

Usage of cardiac simulation results in source localization of focal epicardial arrhythmias using statistical estimation

• Ugur Cunedioglu, Engin Baysoy, Bulent Yilmaz
• 2008 30th Annual International Conference of the…
• 2008

Mapping of the epicardium is possible with the usage of multielectrode venous catheters; however, most of epicardial surface is still inaccessible. To overcome this problem a method called… (More)
