A ventricular outflow tract is a portion of either the left ventricle or right ventricle of the heart through which blood passes in order to enter the great arteries. [1]The right ventricular outflow tract (RVOT) is an infundibular extension of the ventricular cavity that connects to the pulmonary artery.
Right ventricular outflow tract (RVOT) tachycardia is a type of monomorphic ventricular tachycardia originating in the right ventricular outflow tract. RVOT morphology refers to the characteristic pattern of this type of tachycardia on an ECG. [citation needed]
Right ventricular outflow tract (RVOT) tachycardia is the most common VT seen in individuals with ACM. In this case, the EKG shows a left bundle branch block (LBBB) morphology with an inferior axis. Diagnosis
A ventricular outflow tract obstruction means there is a limitation in the blood flow out of either the right or left ventricles of the heart, depending on where the obstruction is. This can lead to cardiac hypertrophy, dilatation of the heart, and ultimately heart failure in some cases. [1]
Usually, APVS occurs together with other congenital heart defects, most commonly ventricular septal defect and right ventricular outflow tract obstruction. It is sometimes considered a variant of Tetralogy of Fallot. [1] The first case of absent pulmonary valve syndrome was reported Crampton in 1830. [2]
Crista supraventricularis is a muscular ridge within the right ventricle of the heart. It is located between the tricuspid and pulmonic valves, at the junction of the right ventricular anterior (free) wall and the interventricular septum. It has a "U-shaped" morphology, which serves as a "trough" for the proximal right coronary artery. [1]
The early bulbus cordis is formed by the fifth week of development. [4] The truncus arteriosus is derived from it later. [2]The adjacent walls of the bulbus cordis and ventricle approximate, fuse, and finally disappear, and the bulbus cordis now communicates freely with the right ventricle, while the junction of the bulbus with the truncus arteriosus is brought directly ventral to and applied ...
Premature ventricular contraction usually originates from an area of Ectopic focus. In this illustration ectopic area is near papillary muscles in the left ventricle. Most commonly in healthy hearts PVCs occur near right ventricular outflow tract (RVOT). A premature ventricular contraction on an EKG, marked by the arrow: Specialty: Cardiology
