New frontiers in arrhythmias.

New frontiers in arrhythmias.

Understanding of the mechanisms responsible for disorders of cardiac rhythm has been increasing rapidly in the past I0 years. A great stimulus to these advances in knowledge has been the recognition in Coronary Care Units of the high mortality associated with some arrhythmias. The principal inroads that have been made into the high mortality of patients with acute myocardial infarction who are ...

[Adenosine in ventricular arrhythmias: moving towards new pathophysiologic frontiers].

Rev Esp Cardiol 2005;58(2):119-20 119 Adenosine-sensitive ventricular tachycardias are a subgroup of tachycardias seen in patients without structural heart disease. They generally appear after episodes of sympathetic hypertony induced by emotional stress or physical excercise.1 The complete mechanism of these arrhythmias is unknown, though there are several arguments to suggest that they origin...

New Frontiers in Applied Probability

Suppose that N is a Z+-valued random variable and that X,X1, X2, . . . is a sequence of independent and identically distributed Z+ random variables independent of N . In this paper we are interested in properties of the conditional variable Nk D =(N | ∑Nj=1 Xj = k). In particular, we want to know the asymptotic behavior of the conditional mean ENk or the conditional variance var Nk as k → ∞. We...
