Webb1 nov. 2000 · While the slow path processing will almost certainly be implemented with a CPU, fast path processing can be implemented with an FPGA, ASIC, co-processor, or maybe just another CPU. This architecture … The slow pathway (which is usually targeted for ablation) is located inferior and slightly posterior to the AV node, often following the anterior margin of the coronary sinus. The fast pathway is usually located just superior and posterior to the AV node. Visa mer AV-nodal reentrant tachycardia (AVNRT) is a type of abnormal fast heart rhythm. It is a type of supraventricular tachycardia (SVT), meaning that it originates from a location within the heart above the bundle of His. AV nodal reentrant … Visa mer The fundamental mechanism of AVNRT is a presence of a dual atrioventricular node physiology (present in half of the population), which … Visa mer Treatments for AVNRT aim to terminate episodes of tachycardia, and to prevent further episodes from occurring in the future. These treatments include physical manoeuvres, … Visa mer The main symptom of AVNRT is the sudden development of rapid regular palpitations. These palpitations may be associated with a fluttering sensation in the neck, caused by near-simultaneous contraction of the atria and ventricles against a closed … Visa mer If the symptoms are present while the person is receiving medical care (e.g., in an emergency department), an ECG may show typical changes that confirm the diagnosis i.e., QRS … Visa mer

WebbDuring sinus rhythm, impulses travel simultaneously through both the fast and slow pathways. That which is transmitted via the fast pathway encounters the end of that of … WebbThe slower pathway recovers quicker (shorter refractory period) and can accept a new signal earlier than the pathway that conducts faster. If a premature beat occurs in the time period when the FP is not ready to receive a new signal, but the SP is, then the early signal will travel down the SP only prolonging the AH interval and PR interval.
