Background fibrosis or fatty infiltration of the human sinoatrial (sa) node is generally believed to represent replacement of the sa nodal cells by connective tissue quantitative analysis, however, has not been performed precisely to validate the interpretation of such histological changes. The sinoatrial node function analysis by means of the voltage clamp technique  customarily the same explanation for the formation of the action poten tial and for the development of the prepotential in both purkinje fiber and sinoatrial node is used.
Vikse j, henry bm, roy j, ramakrishnan pk, hsieh wc, walocha ja, et al (2016) anatomical variations in the sinoatrial nodal artery: a meta-analysis and clinical considerations plos one 11(2): e0148331. The sinoatrial nodal artery (sana) is a highly variable vessel which supplies blood to the sinoatrial node (san) due to its variability and susceptibility to iatrogenic injury, our study aimed to assess the anatomy of the sana and determine the prevalence of its anatomical variations sixty-six.
The various courses of the sinoatrial nodal artery (sana) as seen from a superior view as the use of percutaneous and surgical therapy for supraventricular arrhythmias is increasing[ 64 ], a thorough evidence-based knowledge of the anatomy of the sana is essential for clinical practice[ 35 , 37 , 54 . Correction: anatomical variations in the sinoatrial nodal artery: a meta-analysis and clinical considerations jens vikse, brandon michael henry. Start studying chapter 20 the heart learn vocabulary, terms, and more with flashcards, games, and other study tools search create the sinoatrial node analysis of the electrocardiogram can reveal all of the following, except the a) condition of the conducting system.
The sinoatrial node, the pacemaker of the heart, is a structurally and functionally complex and heterogeneous structure histology, immunohistochemistry, electrophysiology and mathematical modeling of the sinoatrial node are reviewed to reveal the structure-function relationships of the sinoatrial node.
Modelling and analysis of the sinoatrial node modelling and analysis of the sinoatrial node the contraction of the heart is achieved by the regulation of the sinoatrial node (san), the natural pacemaker. Analysis of chronotropic effect of ach introduction: the ionic basis underlying the negative chronotropic effect of acetylcholine (ach) on sinoatrial (sa) node cells is unresolved and controversial in the present study, mathematical modeling was used to address this issue.

Premature atrial stimulation as a key to the understanding of sinoatrial conduction in man presentation of data and critical review of the literature. An analysis of the rate-dependent action of lidoflazine in mammalian sino-atrial node and purkinje fibres hart g, dukes id lidoflazine is an anti-anginal drug whose beneficial effect is to reduce the heart rate increment on exercise.
