Cardiac arrhythmia refers to a variation in the normal rate and/or rhythm of the heart. Though some forms of arrhythmia may only cause minor symptoms, others can be life-threatening. Atrial fibrillation, one of the most common forms of arrhythmia, is known to greatly increase the risk of stroke, while ventricular arrythmias are associated with sudden cardiac death. Greater understanding of arrhythmias, including their pathophysiology, is necessary both for arrhythmia prevention and to improve early recognition and treatment of symptoms in order to maximize treatment efficacy and to reduce mortality.
This Collection welcomes studies that provide new insights into the genetic and molecular underpinnings of cardiac arrhythmias, develop models and technologies for diagnosis, further understanding and investigation, or explore clinical management of the condition.
