Webb20 mars 2010 · At present, there is strong agreement that interstitial cells of Cajal (ICC) are the pacemaker cells that generate slow waves. What has been less clear is the relative role of primary types of ICC, including the network in the myenteric plexus (ICC-MY) and the intramuscular network (ICC-IM). Webb2 juni 2024 · Retrograde capture describes the process whereby the ectopic impulse is conducted retrogradely through the AV node, producing atrial depolarisation. This is visible on the ECG as an inverted P wave (“ retrograde P wave “), usually occurring after the QRS complex. PVCs are said to be “frequent” if there are more than 5 PVCs per minute on ...
