Mapping Techniques

New catheters and electroanatomical mapping systems provide numerous possibilities to acquire information during clinical examinations. Various catheter designs are available for clinical use, ranging from spiral-like versions for high-density mapping, up to basket type versions with 64 electrodes for panoramic mapping. 

Focus of this session will be a comparison of the different methods of data acquisition and visualization, including hardware and signal filtering. Different mapping techniques will be addressed, like voltage, phase and activation mapping. Advantages and challenges for unipolar and bipolar signals will be discussed, together with possible applications. 

Program topics include:

  • One fits all? Catheters and their capabilities

  • From phase to fractionation: Mapping techniques in atrial fibrillation

  • Recording electrograms without loosing information

  • Hunting for ghosts: How much filtering and interpolation is allowed?

Panel discussion:

  • What are the essentials in recording of stable and unstable depolarization patterns of AFib?
