2026年美國心律學會全球高峰會心得: 運動員的心,值得我們更精益求精

如非洲雖然有許多足球員,但非洲各國的醫療資源差異極大。在埃及或南非可以執行基因檢測或核磁共振,但也 有些國家如衣索比亞,甚至連EP man也沒有;而中東對於運動員的篩檢仰賴非政府組織。相較之下,巴西可以每 年給予足球員執行心臟評估,包括ECG與CPET;歐洲國家如義大利會針對孩童普篩、而英國有「Cardiac Risk and the Young (CRY)11」 計畫,針對35歲以下年輕人與有家族史的族群進行全面心電圖篩檢。

2026 European Heart Rhythm Association (EHRA) Conference 會議心得
從技術可行性邁向策略重新定義
奇美醫院心臟內科 李威杰醫師
非常開心有機會參與在巴黎舉辦的European Heart Rhythm Association (EHRA) 2026年會,此次會議匯集 了全球心律不整領域最前沿的研究成果,也提供了豐 富的 simulation 課程與實作訓練,和許多的 case presentation ,讓與會者能夠直接與國際專家交流操作 技巧與臨床經驗,對於所有的醫師而言,不僅是知識 及技術上的更新和剖析,更是對臨床思維與治療策略 的修正及提升。
整體而言,2026年EHRA的重要核心訊息是心律不 整治療正從過去強調「技術可行性」的階段,邁向「 治療策略重新定義」的時代,尤其在 atrial fibrillation (AF) 、 pulsed field ablation(PFA) 、 conduction system pacing(CSP) 、以及 antiarrhythmic drug therapy 等領 域,Late-Breaking Trials 提供了非常具指標性的方向, 顯示未來 electrophysiology(EP) 的發展不再只是新技術 的競爭,而是整體治療邏輯的改變。

VT Substrates 的新策略
The Transmural Activation Interval in Dilated Cardiomyopathy
心內膜與心外膜的 EAM points 分別投影至最近的 CMR 表面。投影距離超過 CMR 表面網格 10 mm 的標測 點,以及距離右心室 CMR 網格 10 mm 以內的心外膜 EAM 點均予以排除。接著,每一個左心室心外膜 EAM 點皆與其正對面的心內膜位置進行配對,並擷取該心內膜位置的插值 unipolar/bipolar voltage 及 LAT 。最 後, CMR-LGE 與 EAM 利用 Carto ParaView 軟體於三維 CMR 表面上進行視覺化呈現,並計算各部位的 CMR 衍生參數。
