서맥 의존성 완전 방실차단 1례

A Case of Bradycardia-Dependent Complete Atrioventricular(A-V) Block

저자들은 안정 와위시 완전 방실차단을 보이고, 좌위로 체위변동과 아트로핀 투여로 야기된 빈맥시 1도 방실차단으로 호전된 서맥의존성 방실차단의 예를 경험하였으며, 인공 심박조율기로 효과적으로 치료하였기에 문헌 고찰과 함께 보고하는 바이다.

Induction of A-V block by tachycardia is a well-known phenomenon. But there are few case reports of bradycardia-dependent A-V block. We report a case of bradycardia-dependent A-V block with review of literatures. This patient was a 52-year-old fe male who complained of dizziness and anterior chest discomfort. Electrocardiographic recording demonstrated complete A-V block. Monitor electrocardiographic recordings during sitting position and after atropine administration demonstrated decrease of degree of block from complete A-V block to first degree A-V block. The occurrence of complete A-V block for bradycardia during supine position suggests a phase 4-dependent block. After a permanent ventricular pacemaker was implanted, the patient recovered and was with out symptoms during 12 months follow up.
