Step 5⃣ A map with a broad area of good LAT for mechanical PVCs with ≥ 95% concordance is generated. At this stage, those points with ≤ 96%, then ≤ 97%, and ≤ 98% concordance can be discarded, making the generated LAT map more precise

A movie (speed x2) to see a MECIE-map being generated. No PVCs before entering the RVOT, just mechanical beats generated and recorded if > 95% concordance

So, it is a LAT map from the ectopic beats generated by the multielectrode catheter! Since a given spline is generating the ectopic beat, it will display an early EGM starting way before QRS onset. All the EGMs adjacent spline are also analyzed and displayed in the LAT map

Step 4⃣All the ectopic beats with < 95% of concordance with the clinical PVC are discarded, while those ectopic beats with ≥ 95% of concordance with the clinical PVC are automatically selected by the mapping software, analyzed in terms of LAT and displayed in an activation map

We describe a novel mapping strategy for patients with infrequent PVCs, called “multielectrode catheter-induced ectopy mapping” (MECIE-mapping), aiming at performing a hybrid activation/template matching map by taking advantage of multielectrode catheter-induced arrhythmogenicity

For patients with infrequent PVCs, activation mapping is useless, and the only remaining technique to determine the SOO is pace-mapping, which has limited spatial resolution

🔥So in conclusion, stop seeing mechanical induced ectopic as an annoying phenomenon, and use it wisely to accurately spot the exact SOO of infrequent PVCs 😵Spoiler: it also works for PVC with higher burdens
