electrical heart position

(redirected from heart position)

e·lec·tri·cal heart po·si·tion

a description of the heart's assumed electrical habitus based upon the form of the QRS complexes in leads aVL, aVF, V1, and V6. Sometimes loosely (and inaccurately) used to describe the frontal plane electric axis.
Synonym(s): heart position

Since the heart position is changing along with the diaphragm, the relative position of the LV at the end-expiration is higher than that at the end-inspiration; the center position of the LV is adopted for depicting the respiratory motion.
First, this maneuver would lead to a variation of the blood pressure transducer position, which is referred to as the heart position (this relationship between heart position and change in pressure transducer position when PLR is initiated from the semi-recumbent position is presented in [Figure 1]) during PLR, which is easily ignored.[sup][9] The variation of arterial transducer position can result in incorrect measurements of pulse contour waveform-derived parameters.
However, PLR might be easier when starting from a supine position, which is without the variation of pressure transducer position (this relationship between heart position and change in pressure transducer position when PLR is initiated from the supine position is shown in [Figure 2]).
The chest X-ray shows the heart position and size, atelectasis, acute respiratory infection, vascular markings and elevated hemidiaphragm.
Instead, begin with a provocative statement that asks for a response, and maintain a "clean heart position"--a sincere desire to see your prospect get what they want, whether or not they get it from you.
Several authors have reported the existence of anatomical variation in arboreal, terrestrial and aquatic snakes (Lillywhite, 1988; Rocha-Barbosa et al., 1999; Rocha-Barbosa et al., 2000), particularly heart position and size of vascular lung (Lillywhite, 1987b), which reflect strategies to adapt to gravitational variations in those habitats.
