Does the cardiological community have the fortitude to correct these mistakes? It is an undeniable fact that cardiac components are not always described according to the position they occupy within the body. This situation was initially drawn to our attention by Francisco Cosio. Thanks to his efforts, an attitudinally correct nomenclature was proposed to account for those features known to be of particular interest to those dealing with abnormal cardiac rhythms.1 The problem, however, is not confined to the electrophysiology laboratory. In this review, we will highlight other areas in which, currently, cardiac structures are not described appropriately with regard to the rest of the thoracic coordinates.Thus, it is an accepted fact that all structures within the body are best described following the convention of the anatomical position (fig 1). Irrespective of the posture, or the location of the body, the subject is considered to be standing upright and facing the observer. Coordinates are then derived according to the three orthogonal planes. Orthogonal planes are at right angles to each other. For the body, two of these planes are in the long axis, while the third plane is transverse and in the short axis. The two planes in the long axis run from front to back, the sagittal plane, and from side to side, the coronal plane. Structures lying within different parts of the sagittal plane are then said to be anterior or posterior relative to each other, according to whether they are to the front or to the back of the body. Within the coronal, or frontal, plane, structures are described as being to the right or the left. Alternatively, within the frontal plane, structures can … ER -
