The branches of the coronary arteries were dissected with special attention to the levels that were considered to be reference points. In Relationship between producers consumers and decomposers subsinuosus interventricular artery, ended before reaching the apex in 21 cases, at the apex in five cases and after the apex in four cases.

The paraconal interventricular artery, ended before reaching the apex in two cases, at the apex in 11 cases and after the apex in 17 cases. The region of the heart apex was irrigated by branches of the left coronary artery, through the paraconal interventricular branch or through both of the interventricular branches. The mean length and number of ventricular branches of the left coronary artery were greater than those of the right coronary artery.

The subsinuosus interventricular branch is a branch of the circumflex branch of the left coronary artery. In the hearts of dogs, the left coronary artery is dominant. The dominance pattern in dogs is different from the dominance pattern in human that is mentioned in the specialized literature. En los corazones humanos la dominancia coronaria es derecha. Sin embargo, no encontramos referencias en la literatura sobre los indicadores de esta dominancia en perros.

Las ramas de las arterias coronarias what is meaning of dominant artery disecadas con especial atención a los niveles considerados como referencias. La rama interventricular subsinuosa es una rama de la rama circunfleja de la arteria coronaria izquierda. En los corazones de los perros, sin embargo, la dominancia es izquierda. La norma de dominancia en los perros es diferente de la norma de dominancia en humanos encontrada en what is meaning of dominant artery literatura.

In some cases, ST segment elevation in right precordial leads in conjunction with inferior leads can be originated by an obstruction of the right coronary artery in its proximal portion, generating an inferior myocardial infarction which involves the right ventricle.

Uncommonly, ST segment elevation in right precordial leads corresponds to proximal occlusion of the right coronary artery, that is to say, a lower infarct with extension to the right ventricle. However, this has not been shown to be very useful in thesetype of patients since it is usually negative, a fact that indicates that ischemia due to CAA presents only occasionally.

The anatomy of right conus artery and its clinical significance. The electrocardiographic evolution in case of infarction shows in these patients an appearance of Q waves in lower leads and a normalization of the ST segment in the previous leads. Electrocardiographic alterations in the antero-septal and inferior what is meaning of dominant artery can be explained by damage to the right ventricle; however, the presence of a very prominent posterior descending artery could explain the left ventricle damage mechanism, which would explain the deviation to the left of the QRS axis on the electrocardiogram. In the late 19th century, the circumflex was used in place of s where that letter was not to be pronounced.
