Asynchrony is characterized by the disruption of ventricular contraction and relaxation and left ventricle systolic performance loss. In this report, three years old female setter who was handed to animal hospital with exercise intolerance was disscussed. At echocardiographic examination carried out because exercise intolerance, interventricular septum among with left ventricul post wall asynchronic movement compatible with ventricular asynchrony was monitored. During left parasternal apical four chamber examination, asynchronic movement was detected at both walls. Although cardiac asynchrony is probably a common case in dogs, it is ruled out because of the lack of clinical evidence in veterinary area like in the case of human medicine. It can be concluded that this disease has clinical significance because of the probability of heart failure, and therefore, needs to be considered in the echocardiographic examinations.

Asenkroni; venriküler kasılma ve gevşeme prosesindeki bozulma ve sol ventriküler sistolik perfomans kaybı ile karakterizedir. Sunulan vakada, hastanemize egzersiz intoleransı şikayeti ile getirilen üç yaşlı, dişi Setter ırkı köpek tartışıldı. Gerçekleştirilen muayenede hastanın kalp ve solunum sayıları ve vücut ısısı normal olarak kaydedildi. Oskültasyonda akciğerin kraniyal loblarında bronşitis ile uyumlu sert veziküler sesler tespit edildi. Egzersiz intoleransı nedeniyle gerçekleştirilen ekokardiyografik muayenede, interventriküler septum ve sol ventrikülün dış duvarı arasında ventriküler asenkroni ile uyumlu hareket gözlendi. Sol parasternal apikal dört boşluk bakıda, her iki duvar arasında asenkronik hareket izlendi. Kardiak asenkroni köpeklerde muhtemelen sık karşılaşılan bir durum olmasına rağmen, Veteriner sahada konu ile ilgili klinik bilgi eksikliği nedeniyle, beşeri hekimlikte olduğu gibi göz ardı edilmektedir. Sonuç olarak; bu hastalık kalp yetmezliğine neden olma ihtimali nedeniyle klinik olarak önem arz eder ve ekokardiyografik muayene sırasında dikkate alınmalıdır.
