Which arrhythmia is commonly monitored in patients with heart disease for early identification of cardiac events?

Atrial fibrillation is commonly monitored in patients with heart disease because it is associated with an increased risk of stroke and other cardiac events. It is characterized by an irregular and often rapid heart rate that can lead to ineffective pumping of the heart. In patients with existing heart conditions, this arrhythmia can signify a higher likelihood of complications, making early identification crucial for timely intervention. Monitoring for atrial fibrillation allows healthcare providers to initiate appropriate management strategies, such as anticoagulation therapy, to reduce the risk of stroke and optimize heart function.

In contrast, while other arrhythmias like ventricular tachycardia and bradycardia can be significant, atrial fibrillation is more prevalent and notably impacts patients with heart disease, prompting proactive monitoring. Sinus arrhythmia is usually a normal variant, especially in younger individuals and is not typically a primary concern in the context of heart disease.
