Final answer:
The radiofrequency (RF) ablation energy range for AVNRT slow pathway ablation typically varies between 20 to 50 watts, with the duration of energy application lasting from 30 to 60 seconds, according to the individual treatment protocol and the response during the procedure.
Step-by-step explanation:
The question asks about the radiofrequency (RF) ablation energy range used for atrioventricular nodal reentrant tachycardia (AVNRT) slow pathway ablation. AVNRT is a common type of supraventricular tachycardia that is caused by the presence of an extra pathway, known as the slow pathway, within the AV node. The treatment for this condition often involves RF ablation, which is a minimally invasive procedure that uses radiofrequency energy to destroy the abnormal electrical pathway causing the tachycardia.
During RF ablation, the energy range used can vary depending on the specific equipment and the protocol of the electrophysiology lab. However, a typical energy range for RF ablation of the AVNRT slow pathway is between 20 to 50 watts. The duration of energy application is commonly between 30 to 60 seconds, again depending on the individual circumstances and the response received during the procedure.
