Abstract

A 17-year-old patient presented with frequent palpitations, where the tachycardia was not sustained and could not be induced, making it impossible to pinpoint the earliest activation site using the activation map. However, by utilizing a dual-chamber electrogram-based pace mapping technique, we successfully identified the origin and achieved effective treatment.

摘要

一名17岁患者出现频繁心悸，其心动过速不持续且无法诱发，这使得利用激动标测图确定最早激动部位变得不可能。然而，通过使用基于双腔电图的起搏标测技术，我们成功确定了起源并实现了有效治疗。
