Web9 de feb. de 2024 · Atrioventricular (AV) reciprocating tachycardia is the second-most common supraventricular tachycardia in practice, with greater than 95% catheter ablation success rate and 1% risk of complete heart block, most commonly after ablation of septal and posteroseptal accessory pathways.1 Mapping of the accessory pathway (AP) is … An accessory pathway is an additional electrical connection between two parts of the heart. These pathways can lead to abnormal heart rhythms or arrhythmias associated with symptoms of palpitations. Some pathways may activate a region of ventricular muscle earlier than would normally occur, referred to as pre-excitation, and this may be seen on an electrocardiogram. The combination of an accessory pathway that causes pre-excitation with arrhythmias is known as W… lvis python https://automotiveconsultantsinc.com
