A ventricular septal defect ( VSD) is a defect in the ventricular septum, the wall dividing the left and right ventricles of the heart. The extent of the opening may vary from pin size to complete absence of the ventricular septum, creating one common ventricle. The ventricular septum consists of an inferior muscular and superior membranous ...
A medical monitoring device displaying a normal human heart rate. Heart rate (or pulse rate) [1] is the frequency of the heartbeat measured by the number of contractions of the heart per minute ( beats per minute, or bpm). The heart rate varies according to the body's physical needs, including the need to absorb oxygen and excrete carbon ...
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
Ventricular tachycardia ( V-tach or VT) is a cardiovascular disorder in which fast heart rate occurs in the ventricles of the heart. [3] Although a few seconds of VT may not result in permanent problems, longer periods are dangerous; and multiple episodes over a short period of time are referred to as an electrical storm. [3] [6] [7] Short ...
The heart has the shape of a pyramid, with its apex pointing towards the left nipple while its base forms the posterior surface of the heart. Other surfaces are the anterior, inferior (or diaphragmatic), and two pulmonary surfaces facing the lungs. Its longest dimension (apical to base) is broadly 12–13 cm, while the average weight is 250 ...
Ventricular hypertrophy ( VH) is thickening of the walls of a ventricle (lower chamber) of the heart. [1] [better source needed] Although left ventricular hypertrophy (LVH) is more common, right ventricular hypertrophy (RVH), as well as concurrent hypertrophy of both ventricles can also occur. Ventricular hypertrophy can result from a variety ...
Der Double outlet right ventricle (DORV) ist eine angeborene Fehlbildung des Herzens, bei der die großen Arterien Aorta und Arteria pulmonalis ausschließlich aus dem rechten Ventrikel entspringen. Parallel besteht notwendigerweise immer ein Ventrikelseptumdefekt (VSD), welcher den einzigen Ausgang des linken Ventrikels darstellt, sowie häufig auch eine Pulmonalstenose .
