Reentry can occur within a small local region of the heart (local reentry) or it can occur between the atria and ventricles (global reentry). An example of local reentry would be a region within …

2023年6月23日 · A reentry arrhythmia is an abnormality in your heart’s rhythm in which electrical impulses in your heart stray from their usual path and form a closed-loop circuit....

2023年7月4日 · A reentry arrhythmia is a self-sustaining cardiac rhythm abnormality in which the action potential propagates in a manner analogous to a closed-loop circuit. It is a disorder of …

Re-entry is the most common cause of supraventricular and ventricular arrhythmias that require treatment. Most cases of atrial flutter are due to re-entry and re-entry has a fundamental role in …

Reentry occurs when a propagating impulse fails to die out after normal activation of the heart and persists to re-excite the heart after expiration of the refractory period. Evidence implicating …

Reentry is fundamentally different from automaticity or triggered activity in the mechanism by which it initiates and sustains cardiac arrhythmias. Circus movement reentry occurs when an …

Re-entry ventricular arrhythmia is a type of paroxysmal tachycardia occurring in the ventricle where the cause of the arrhythmia is due to the electric signal not completing the normal …

2023年7月30日 · This constant re-excitation of the myocardium can manifest in dangerous arrhythmias, syncope, or even sudden death. Reentry has a characteristic mechanism by …

Re-entry can occur at many sites in the heart; common examples are the SA node (premature atrial beats), the atria (atrial flutter or fibrillation), the AV node (paroxysmal supraventricular …

The difference between such spiral waves, or rotors, and leading circle reentry is that in the latter the core is permanently refractory, whereas in the former the core is excitable but not excited. …
