摘要

心臟是人類的核心器官，心臟節律性的規則運作才能維持身體的正常功能，節律異常的心臟疾病困擾臨床醫師，直到1958年，人類史上第一個心臟節律器裝置出現，經過快速不斷的創新與改良，迄今美國已有超過四百萬人接受此類的節律裝置，但伴隨而來的裝置感染引起另一種醫療問題，粗估感染發生率為1.5~2.4%。心臟植入式電子裝置的感染因素可能和宿主、裝置類型與植入技術複雜程度有關，文獻指出引起感染的危險因子如：潛在內科共病、腎衰竭、心衰竭、糖尿病、抗凝固劑與類固醇使用，引起的致病菌以革蘭氏陽性菌為主，其中以金黃色葡萄球菌較常見。臨床表徵為局部紅、腫、熱、痛、化膿性分泌物、潰瘍等，也可產生敗血症或感染性心內膜炎。局部感染以保守性治療為主，主要是接受有效抗微生物製劑7~14天，全身性感染需要移除裝置與延長藥物治療時間。預防感染有效的方式為術前預防性抗生素使用，或是使用包覆有抗微生物製劑的電子裝置，有效減少術後出血腫塊產生也能降低心臟植入式電子裝置的感染。

The heart is a vital organ for human beings, and its regular rhythmic performance ensures the proper functioning of the body. Clinical physicians were concerned about heart pacing disorder-related diseases until 1958, when the first pacemaker in medical history was utilized. More than four million people have received cardiac implantable electronic devices (CIEDs) after rapid cardiac disease development and intervention over the past half century. However, cardiac implantable electronic device infections brought upon other medical issues. The crude incidence of CIED infection is 1.5-2.4%, and electronic device infections may be attributed to patient factors, device types, and the number of devicerelated interventions. The significant risk factors for patient comorbidities are medical illness, renal failure, heart failure, diabetes, usage of anti-coagulant agents, and steroids. Gram-positive bacteria are usually the cause of infection, of which Staphylococcus aureus is the most common. Clinical manifestations include skin reddening, warmth, edema, pain, purulent discharge, and erosion, and sometimes, severe sepsis and infective endocarditis. Conservative medical therapy may control localized infection, usually after 7-14 days of antimicrobial agent use. Systemic infections require removal of the electronic device and longer durations of antiinfection therapy. Strategies to prevent device infections have been proposed, such as pre-procedure prophylaxis antimicrobial agents, antimicrobial agent-covered envelopes for electronic devices, and measures to decrease the growth of post-procedure hematomas.
