Loss-of-function mutations in the human ERG1 potassium channel (hERG1) frequently underlie the long QT2 (LQT2) syndrome. The role of the ERG potassium channel in cardiac development was elaborated in an in vivo model of a homozygous, loss-of-function LQT2 syndrome mutation. The hERG N629D mutation was introduced into the orthologous mouse gene, mERG, by(More)
Entrainment is an important pacing maneuver that can be used to identify reentry as a tachycardia mechanism and define components of the circuit. This review examines how principles of entrainment can be used to arrive at a firm supraventricular tachycardia diagnosis using a simple algorithm and builds a foundation for the application of entrainment to more(More)
The approach to supraventricular tachycardia (SVT) diagnosis can be complex because it involves synthesizing baseline electrophysiologic features, features of the SVT, and the response(s) to pacing maneuvers. In this two-part review, we will mainly explore the latter while recognizing that neither of the former can be ignored, for they provide the context(More)
BACKGROUND Population-based screening for atrial fibrillation (AF) is a promising public health strategy to prevent stroke. However, none of the published reports have evaluated comprehensive screening for additional stroke risk factors such as hypertension and diabetes in a pharmacy setting. METHODS The Program for the Identification of 'Actionable'(More)
The field of cellular microbiology is relatively new and incorporates aspects of microbiology and host cellular biology. The first edition of this text, published in 2000, was novel and well received. In general, this new edition is also well written and includes many of the most important recent advances in the field (e.g., microarrays and genome(More)
