arrhythmia
Meaning: An abnormal heart rhythm in which the heart beats too quickly, too slowly, or irregularly. A common cardiac condition that ranges from benign to life-threatening.
Arrhythmias result from disruptions to the electrical signals that coordinate heartbeats. Common types include atrial fibrillation (the most prevalent sustained arrhythmia), supraventricular tachycardia, and ventricular fibrillation. Symptoms may include palpitations, dizziness, breathlessness, or fainting, though many arrhythmias are asymptomatic. Treatment options include medication, cardioversion, catheter ablation, and implantable devices such as pacemakers. The term collocates with 'cardiac,' 'ventricular,' 'atrial,' and 'supraventricular.'
