Arrhythmia refers to the abnormal origination or conduction of impulses in the heart due to abnormal activation of the sinoatrial node, slow conduction, blockages, or passage through abnormal pathways, leading to abnormalities in the frequency and/or rhythm of the heartbeat. Arrhythmias are a significant group of cardiovascular diseases. They can occur alone or in conjunction with other cardiovascular diseases. The prognosis of arrhythmias depends on their causes, triggers, trends in progression, and whether they lead to severe hemodynamic disturbances, potentially causing sudden death or continuous impairment of heart function leading to heart failure.
