Widely known as the premier electrophysiology text, Josephson’s Clinical Cardiac Electrophysiology provides a thorough understanding of the mechanisms of cardiac arrhythmias and the therapeutic interventions used to treat them. Dr. David J. Callans, personally chosen and trained by Dr. Mark Josephson, continues the tradition of excellence of previous editions while bringing the text fully up to date in every area of this complex field. The sixth edition provides highly visual guidance on the electrophysiologic methodology required to define the mechanism and site of origin of arrhythmia – enabling you to choose the safest and most effective therapy for each patient.

The heart’s electrical activity is represented on the monitor or ECG tracing by three basic waveforms: the P wave, the QRS complex, and the T wave. A U wave is sometimes present. Between the waveforms are the following segments and intervals: the PR interval, the ST segment, and the QT interval. Although the letters themselves have no special significance, each component represents a particular event in the depolarization–repolarization cycle. Calculating the Heart Rate There are several methods for determining heart rate. Our first method is simple. Count the number of QRS complexes over a 6 second interval. Multiply by 10 to determine heart rate. This method works well for both regular and irregular rhythms. In the first image, we can count 5 QRS complexes, so the heart rate is 50. The second method uses small boxes. Count the number of small boxes for a typical R-R interval. Divide this number into 1500 to determine heart rate. ECG tracings are recorded on grid paper. The horizontal axis of the ECG paper records time, with black marks at the top indicating 3 second intervals. Each second is marked by 5 large grid blocks. Thus each large block equals 0.2 second. The vertical axis records EKG amplitude (voltage). Two large blocks equal 1 millivolt (mV). Each small block equals 0.1 mV. Within the large blocks are 5 small blocks, each representing 0.04 seconds.
July 29, 2021 – Results from a new clinical trial found human-oversight dependent continuous electrocardiography (ECG) monitors to more accurately detect significant arrhythmias than artificial intelligence (AI) algorithm-dependent mobile cardiac telemetry (MCT). The study showed there was a 209% increase in detection when humans evaluated the monitoring as compared to algorithmic monitoring to flag events.

This is the latest edition of the classic introductory text to electrophysiology. It covers many topics that are central to the field including the electrical properties of the cell membrane. New features include extra, detailed illustrations.\nThis new edition of the classic introductory text to bioelectricity (electrophysiology) is aimed at biomedical engineering students. It expands on the developments since the successful last edition. The book is authored by two eminent biomedical engineering professors at Duke University who discuss many topics that are central to biophysics and bioengineering and the quantitative methods employed. In addition, this classic text will be complemented by a Bioelectricity Solutions Manual, sure to aid the speed and assimilation of the Teaching Text material to the new Biomedical Engineering student. In the first edition of Bioelectricity, Plonsey and Barr provided an introduction to electrophysiology following a quantitative approach. In the second edition they address new discoveries in the field of ion channels and provide an introduction to electrophysiology utilizing a quantitative approach.
