Abstract

We present an interesting case of ‘‘pseudo’’ atrial fibrillation which was further diagnosed as atrial standstill with irregular junctional ectopic rhythm during electrophysiologic study. A 56-year-old woman presented to a health facility with symptoms of palpitation, lightheadedness, and shortness of breath. Upon detection of irregular rhythm with narrow QRS complexes and no visible P waves on the electrocardiogram, newly developed atrial fibrillation was considered and a direct current cardioversion was performed, during which cardiac asystole developed necessitating cardiopulmonary resuscitation. The patient was then transferred to our institution. Echocardiographic examination showed biatrial dilatation, normal left ventricular systolic function, marked left ventricular hypertrophy, severe aortic stenosis, moderate mitral regurgitation, and severe tricuspid regurgitation. The electrocardiogram showed an irregular rhythm with narrow QRS complexes without any fibrillatory f waves and 24-hour Holter monitoring revealed three episodes of ventricular asystole lasting for more than 3.5 seconds. During the electrophysiologic study, no electrical activity was observed at the high and low levels of the right atrial lateral free wall and septal wall. The final diagnosis was established as atrial standstill and irregular junctional ectopic rhythm. The patient refused aortic valve replacement and died due to progression of the underlying disease one year following permanent pacemaker implantation.

Özet

Bu yazıda, ilginç bir “yalancı” atriyal fibrilasyon olgusu sunuldu; daha sonra yapılan elektrofizyolojik çalışma sayesinde hastaya atriyal duraklama ve düzensiz ektopik kavşak ritmi tanısı kondu. Elli altı yaşında kadın hasta bir sağlık kuruluşuna çarpıntı, bayılma hissi ve nefes darlığı yakınmalarıyla başvurmuş. Elektrokardiyogramında dar QRS kompleksinin eşlik ettiği düzensiz ritim izlenmesi ve P dalgalarının görülmemesi üzerine, yeni gelişen atriyal fibrilasyon düşünülerek hastaya doğru akımlı kardiyoversiyon uygulanmış ve bu sırada kardiyopulmoner canlandırma girişimi gerektiren kardiyak asistol gelişmiş. Hasta daha sonra kurumumuza yönlendirildi. Ekokardiyografik incelemede iki atriyumda da genişleme, belirgin sol ventrikül hipertrofisi, ciddi aort darlığı, orta derecede mitral ve ciddi triküspit yetersizlik izlenirken, sol ventrikül sistolik fonksiyonu normal bulundu. Elektrokardiyografide dar QRS kompleksinin eşlik ettiği düzensiz ritim ve fibrillatuvar f dalga yokluğu, 24 saatlik Holter izleminde ise 3.5 saniyeden uzun süren üç adet ventrikül asistol atağı izlendi. Elektrofizyolojik çalışmada, sağ atriyum lateral serbest duvarının ve septal duvarının yukarı ve aşağısında elektriksel aktivite izlenmedi. Bu bulgularla tanı atriyal duraklama ve düzensiz ektopik kavşak ritmi olarak kondu. Hasta aort kapağı değişimini kabul etmedi ve kalıcı kalp pili yerleştirildikten bir yıl sonra altta yatan hastalığının ilerlemesi nedeniyle kaybedildi.
