초록

8세령 수컷 요크셔테리어 잡종견(몸무게: 7.5kg)이 운동불내성과 실신을 주증상으로 강원대학교 동물병원에 내원하였다. 초기 심장 검사에서 경미한 이첨판 역류증이외에 특별한 이상소편은 관찰되지 않았다. 운동내성검사에서 환자는 심각한 chronotrophic incompetence소견을 보였고, 1시간-디지털 심전도 검사에서 돌발적으로 발생하여 종료되는 발작성 동성 빈맥소견(심박수: 156-172회)을 보였다. 추가적인 미주신경 자극시험과 verapamil 반응시험에서 빈맥이 종료되는 소견을 보였다. 이러한 소견을 토대로 본 증례는 동방회귀성 빈맥증으로 진단내렸다. 환자는 diltiarem과 enalapril로 치료하였고, 한달 후 재검사에서 운동 불내성 소견은 지속적으로 보였지만, 추가적인 실신소견은 관찰되지 않았다.

An 8-year-old intact male Yorkshire cross dog (7.5 kg of body weight) was referred with the primary complaint of exercise intolerance and occasional syncope. Initial cardiological examination could not identify any abnormalities except mild mitral regurgitation. Exercise stress test revealed chronotrophic incompetence. Furthermore the 1 hr-digital event recording found the sudden onset of paroxysmal sinus tachycaridas (156-172 bpm) lasting few minutes and stopping abruptly. In addition, the tachycardia terminated by vagal maneuver and verapamil administration. Based on this finding, the case was diagnosed as sinoatrial reentrant tachycardia (SART). The dog was treated with diltiazem and enalapril. Although the dog still has exercise intolerance, no syncope has been observed after medication.
