Analysis of intracardiac electrogram of heart arrthytmias in the spectral domain
 Karlíková, Adéla ; Králík, Martin (referee) ; Mézl, Martin (advisor)
The most important aspect of successful ablation and destruction of arrhythmia is to find the place where arrhythmia spreads. The site of initial activation can be found by conventional or complex techniques. This thesis describes a new conventional method that can also be applied in practice. It was found that the closer is catheter to the place of the initial activation the more dominant frequency shifts to the higher values. We will use this fact in creating an algorithm which will compare frequency values in the frequency spectrum. This algorithm will also assess how far is the catheter located from the site of the origin of the arrhythmia. In the conclusion of the thesis is an evaluation of the measured clinical data and a comparison of the effectiveness of the method.
