(FIT)-Module 3 Workshop 5: Invasive and Non-Invasive Correlation-Stevenson Case 3 Answer

Video Transcription

Video Summary

The video analyzes various cardiac arrhythmias using activation maps. In panel A, a focal tachycardia with an RV cycle length of 280 ms is identified, with activation emerging centripetally. The second panel reveals two activation sequences: a focal pattern on the LV endocardium and reentry in the LV epicardium, the latter aligning closely with a 310 ms tachycardia cycle length. The third panel describes another reentry circuit near the mitral valve, matching a 370 ms cycle length. The focal tachycardia is specifically highlighted in figure 3A.
