The sequence of right and left atrial contractions was analysed in 8 patients during spontaneous sinus rhythm and paced left atrial rhythm. During sinus rhythm, the beginning or peak of the right atrial a wave invariably preceded the beginning or peak of the left atrial a wave by a median of 32 and 34 msec, respectively. During paced left atrial rhythm, the beginning or peak of the right atrial...

We propose some refinements for the second inequality in $$ \frac{1}{2}\left\Vert A\right\Vert \le w(A)\le \left\Vert A\right\Vert, where A ∈ B(H). In particular, if is hyponormal, then, by refining Young with Kantorovich constant K K(⋅, ⋅), we show that \frac{1}{2{\operatorname{inf}}_{\left\Vert x\right\Vert =1}\zeta (x)}\left|\left\Vert A\right.\right|++\left|\left.{A}^{\ast}\right\Vert \righ...

We studied two patients with a peculiar congenital disturbance of ocular motility in which the horizontal movements of the left eye were always opposite the normal expected direction. The common features were: (1) congenital monocular adduction palsy and exotropia of the left eye; (2) simultaneous abduction of both eyes (divergence) on attempted dextroversion; (3) ocular torticollis, head turne...

Since, sports activities are likely to be changes in various parameters of plantar pressure distribution during walking to create, This study compared patterns of plantar pressure distribution between right and left feet and their relationship with anthropometric parameters. 10 elite wrestler with the average and standard deviation of age: 23.6±3.33 yrs, height: 173.5±7.67 cm and mass: 83.3±21....

The natural history of pulmonary artery pressure and extrapulmonary shunting in acute hyaline membrane disease was studied by serial Doppler echocardiography in 57 preterm infants, 38 with, and 19 without, hyaline membrane disease. Pulmonary artery pressure was assessed non-invasively by its inverse relationship with the ratio of pulmonary artery Doppler time to peak velocity: right ventricular...
