Cardiac arrhythmias, a diverse range of irregular heart rhythms, impose a significant global burden on individuals and healthcare systems. These disruptions in the heart's electrical activity can result in complications, varying from minor discomfort to life-threatening events. The multifaceted impact of cardiac arrhythmias extends to patients' quality of life, escalating healthcare costs, and demanding extensive resources for diagnosis and management. Early detection in acute settings is paramount, where prompt intervention profoundly influences patient outcomes. The electrocardiogram (ECG) serves as a fundamental tool, offering real-time insights into the heart's electrical activity and enabling swift identification of irregular rhythms. This review article, initiated on March 5, 2024, emerged from an in-depth examination of current academic literature. The primary focus was to glean insights into the effects of cardiac arrhythmias on individuals' lives, emphasizing the critical role of early detection. The review explored the impact of routine ECG monitoring on cardiac arrhythmia outcomes and its application in acute healthcare settings. Continuous ECG monitoring assumes a pivotal role in early detection and comprehensive management in acute settings. Its real-time surveillance empowers healthcare professionals to promptly identify irregular rhythms, facilitating timely interventions and mitigating adverse outcomes. Integration with telemedicine, remote monitoring, and trend analysis enhances its impact, providing valuable insights for immediate decision-making and long-term management. The documentation of arrhythmia patterns over time contributes to a nuanced understanding of the patient's cardiac status, supporting personalized and effective interventions. As technology advances, the evolving landscape of continuous ECG monitoring holds promise for refining its role, contributing to improved patient outcomes and a proactive approach to the challenges presented by cardiac arrhythmias in acute care.
