25. Potential interests of heart rate lowering drugs -- Laperche et al. 81 (4): 336 -- Heart
- www.heartjnl.com
- The ventricle is a generator of hydraulic energy, which transfers the mechanical energy of contraction to the blood accumulated in the ventricular chambers in order to eject it through the arterial system. ...
- Experimental studies showed that such a drug effectively attenuated ischaemia induced by exercise and improved myocardial perfusion in the ischaemic area, without negatively affecting non-ischaemic zones or the overall contractile function of the left ventricle. ...
- Total mechanical energy of a ventricle model and cardiac oxygen consumption. ...
- Heart rate and force-frequency effects on diastolic function of the left ventricle in exercising dogs. ...

- physrev.physiology.org
- A higher maximum turnover rate of ~200/s has been derived from measurements of transient pump currents in excised patches of rat ventricle cells (42). ...
- Figure 7A shows, for example, that Ip of a guinea pig ventricle cell in Na+-poor solution (1. ...
- Thus the shape of the Ip-V relationship in guinea pig ventricle cells was explained by assuming that depolarization of the sarcolemma enhances the voltage-dependent step of the Na+ translocation such that the voltage-insensitive K+ import becomes rate limiting for the Na+-K+ pump cycle at positive membrane potentials (6).
- Concerning transient pump currents, the rate constants of current decline during Na/Na exchange in guinea pig ventricle cells exhibited a voltage-independent Q10 value of ~3 (130). ...
- In contrast to the just described observations on guinea pig ventricle myocytes, a study on rat ventricular cells did not detect any -adrenergic regulation of the Na+-K+-ATPase (101). ...

- The ventricular enlargement is consistent with the previous studies showing both increased ventricle-to-brain ratio in schizophrenics (Van Horn and McManus, 1992) and increased ventricular volume (Degreef et al. ...

- Although -adrenoceptor-mediated inotropic effects in rat ventricle appear to occur primarily via 1B-adrenoceptors (Michel et al. ...
- , 1985), human left ventricle (Bristow et al. ...
- One reason for these differences between atrial and ventricular myocardium might be the fact that parasympathetic innervation is much more dense in sinoatrial and atrioventricular nodes than in left ventricle of the human heart (Kent et al. ...
31. Regulation of beta -Adrenoceptor Signaling in Cardiac Function and Disease -- Dzimiri 51 (3): 465 -- Pharmacological Reviews
- pharmrev.aspetjournals.org
- The receptor is expressed in several heart regions, including the sinoatrial node, atrium, and ventricle. ...
- However, in dogs with right heart failure, the reduction in 1-AR density was shown to occur only in the failing right ventricle, whereas cardiac inotropic responses to receptor stimulation were reduced in both the right and left ventricles (Lai et al. ... The decrease in 1-AR density in the failing human left ventricle is accompanied by a similar reduction in 1-AR mRNA levels (Ihl-Vahl et al. ...
