Molecular and Cellular Mechanisms of Cardiac Arrhythmias

then slowly repolarize, which is denoted as the T wave on the ECG, leading to cardiac relaxation and completion of one cardiac cycle. The rhythmic activity of the human heart is clearly apparent by ultrasound after only five weeks of gesta-Department of Cardiology Children's Hospital tion. It is remarkable to think how flawlessly the heart performs in the course of one's life, beating ‫07ف‬ tim...

Principles of cardiac electric propagation and their implications for re-entrant arrhythmias.

Re-entrant DNA gels

DNA is acquiring a primary role in material development, self-assembling by design into complex supramolecular aggregates, the building block of a new-materials world. Using DNA nanoconstructs to translate sophisticated theoretical intuitions into experimental realizations by closely matching idealized models of colloidal particles is a much less explored avenue. Here we experimentally show tha...

Re-entrant ventricular arrhythmias in the late myocardial infarction period. 2. Patterns of initiation and termination of re-entry.

The electrophysiologic mechanisms for the initiation and termination of re-entrant ventricular arrhythmias (RVA) were critically analyzed in dogs 3-7 days following ligation of the anterior descending coronary artery, utilizing direct recordings of the re-entrant pathway (RP) from the epicardial surface of the infarction zone. Re-entry could occur during a regular cardiac rhythm if the heart ra...
