Microelectrode studies on concealment of multiple premature atrial responses.
the conduction of premature responses has resulted from the precise and degwtff W@kW& by Langendorf, a n d K a t z a n d P i cardiograms of patients with arrhythmias. The elaborate associates on experimentally evoked arrhythmias have further increased our knowledge of conduction of premature responses. Recently, Moe et al. demonstrated that as many as six premature atrial responses can be conce...
متن کاملMicroelectrode studies on retrograde concealment of multiple premature ventricular responses.
Retrograde concealment of serially evoked premature ventricular responses was studied in an isolated preparation of rabbit atria and ventricles. Transmembrane potentials were recorded simultaneously from single cells within the atrioventricular (A-V) node and ventricular specialized conduction system, together with atrial and ventricular bipolar electrograms. In these experiments, retrograde co...
متن کاملSinus node response to premature atrial stimulation in the rabbit studied with multiple microelectrode impalements.
In this study we investigated the response of the isolated rabbit sinus node to ectopic atrial premature beats elicited late in the atrial cycle. In three experiments the response of at least 45 different fibers of the sinus node was recorded, whereas, in other experiments, investigation was less extensive. In this way the spread of activation of the total pacemaker area could be mapped accurat...
متن کاملEffect of vocal stimulation on responses of premature infants
Background and Objectives: There are studies that support music and singing as appropriate developmental care for premature infants, thus, we conducted this study to investigate the physiological and behavioral responses of premature infants to Quran recitation, lullaby music and silence. Methods: In a randomized controlled trial (2011-2012),120 premature infants in the Neonatal Unit (NNU) at I...
متن کاملMicroelectrode study of alternating responses to repetitive premature excitation in canine Purkinje fibers.
Microelectrode studies were performed to produce alternation of coupled beats in the specialized conduction system of the heart and to determine the underlying mechanisms of their production. A typical preparation consisted of a superfused Y-shaped bifurcating segment of canine Purkinje tissue, in which the two branches of the Y were approximately symmetrical and terminated in a functionally co...
