Warren Jackman's Art of War: A Sniper's Approach to Catheter Ablation-Figure Chapter 4

Figure Chapter 4

Pdf Summary

The document appears to be composed of figures and diagrams describing various heart rhythms, pacing techniques, and the outcomes of electrophysiological studies. It includes labels and measurements for different intervals and leads during induced tachycardias, ablation procedures, and pacing tests, particularly around structures such as the right ventricle (RV), right atrial appendage (RAA), and His bundle (HB). Descriptions and schematic representations focus on identifying arrhythmias, such as Atrial Tachycardia (AT), Atrioventricular Nodal Reentrant Tachycardia (AVNRT), and Atrioventricular Reentrant Tachycardia (AVRT), using pacing techniques and electrophysiological maneuvers like overdrive pacing, ventricular extrastimulus, and para-Hisian pacing. Specific pathways and conduction patterns, such as antegrade and retrograde conduction through the atrioventricular node (AV node) and accessory pathways (APs), are explored in various cycles and intervals. Figures captioned with specific time measurements (e.g., 200 ms, 360 ms) indicate objective tracing and diagnosis techniques used in clinical electrophysiology. The document mentions specific clinical scenarios, such as the case of a 5-year-old girl with wide-complex tachycardia (WCT), suggesting it serves as a diagnostic reference for pediatric electrophysiologists as well. Overall, the text is highly technical, targeting medical professionals involved in cardiac rhythm management and electrophysiological studies.
