Resumo: The T-wave in the canine electrocardiogram can be positive, negative, or biphasic in most leads, while his amplitude should not be greater than 25% of the R wave. However, since the 1960’s persists controversy regarding the polarity of the T wave in Chihuahuas when compared to other canine breeds. This study aimed to clarify the polarity and shape of the T-wave in the lead V-10 in a group of healthy Chihuahuas. Retrospective eletrocardiographic study with a sample of 20 private client-owned Chihuahuas. The conclusion was that the polarity of the T-wave is usually negative and the shape is asymmetric, type “slow-fast/down-up”, in all dogs studied.

Sin embargo, desde la década de 1960 persiste la controversia respecto a la polaridad de la onda T en los Chihuahuas en comparación con otras razas caninas. Nuestro estudio tuvo como objetivo aclarar la polaridad y la forma de la onda T en la derivación V-10 en un grupo de chihuahuas sanos. Estudio electrocardiográfico retrospectivo con una muestra de 20 chihuahuas propiedad de clientes privados. La conclusión fue que la polaridad de la onda T suele ser negativa y la forma es asimétrica, tipo “lento-rápido/abajo-arriba”, en todos los perros estudiados.A onda T no eletrocardiograma canino pode ser positiva, negativa ou bifásica na maioria das derivações, enquanto sua amplitude não deve ser superior a 25% da onda R.
