Latent Heart Block.
I have used the term "Latent Heart Block" to indicate a prolonged P-R interval without any manifest degree of block, such as dropped beats or 2 :1 block. This paper is a clinical study of a series of such cases, mainly from the point of view of the xtiology and significance of the condition. One might guess that latent heart block would be found in the same cases as, but at an earlier stage tha...
متن کاملHyperkalemia-induced complete heart block
Background: Potassium, as an extracellular ion, plays an important role in the electrophysiologic function of the myocardium and any change in extracellular concentration of this ion might have a marked impression upon myocyte electrophysiologic gain. High serum potassium levels are thought to impair pulse conduction in Purkinje fibers and ventricles more than that in the Atrio...
متن کاملBlock clustering with collapsed latent block models
We introduce a Bayesian extension of the latent block model for model-based block clustering of data matrices. Our approach considers a block model where block parameters may be integrated out. The result is a posterior defined over the number of clusters in rows and columns and cluster memberships. The number of row and column clusters need not be known in advance as these are sampled along wi...

متن کاملLatent Block Model for Contingency Table
Although many clustering procedures aim to construct an optimal partition of objects or, sometimes, of variables, there are other methods, called block clustering methods, which consider simultaneously the two sets and organize the data into homogeneous blocks. This kind of methods has practical importance in a wide of variety of applications such as text and market basket data analysis. Typica...
