Rhythm versus conduction. Your heart rhythm is the way your heart beats. Conduction is how electrical impulses travel through your heart, which causes it to beat. Some conduction disorders can cause arrhythmias, or irregular heartbeats. Three common conduction disorders are: Bundle branch block; Heart block; Long QT Syndrome; Bundle branch block

Cardiac conduction problems cause issues with your heart’s rhythm. Some common heart rhythm disorders include: Arrhythmia. An irregular heart rhythm, including atrial fibrillation (Afib). Bundle branch block. A block in the Purkinje fibers on one side of your heart, causing arrhythmia. Heart block. Impaired electrical signals between your ...

Cardiac arrhythmias encompass a range of conditions characterized by abnormal heart rhythms, affecting millions globally and significantly contributing to morbidity and mortality. This review provides a comprehensive analysis of the current ...

Altered conduction velocity (CV) provides a key substrate for arrhythmogenesis, with slowed CV increasing the probability of re-entrant arrhythmias by reducing the length scale over which re-entry can occur.

Arrhythmia and conduction disturbances may be asymptomatic or cause palpitations (sensation of skipped beats or rapid or forceful beats), symptoms of hemodynamic compromise (eg, dyspnea, chest discomfort, presyncope, syncope), or cardiac arrest. Occasionally, polyuria results from release of atrial natriuretic peptide during prolonged ...
