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 ... Webb14 nov. 2024 · Slow waves originate in specific cortical regions and travel over the brain, each with a distinct site of origin and pattern of propagation. Moreover, slow waves with multiple negative peaks may simply result from the superimposition of multiple slow oscillations, each with a distinct origin and/or path of propagation. 8 tagalog reflection paperA slow-wave potential is a rhythmic electrophysiological event in the gastrointestinal tract. The normal conduction of slow waves is one of the key regulators of gastrointestinal motility. Slow waves are generated and propagated by a class of pacemaker cells called the interstitial cells of Cajal, which also act … Visa mer In the human enteric nervous system, the slow-wave threshold is the slow-wave potential which must be reached before a slow wave can be propagated in gut wall smooth muscle.
