Abstract
Objective: To evaluate advancements in cardiac monitoring technologies in intensive care units (ICU) and explore their implications for nursing practice, focusing on effective data interpretation, alarm management, and strategies to enhance patient outcomes.
Methods: This review utilized a narrative approach, synthesizing findings from peer-reviewed journals, clinical guidelines, and recent technological assessments published between 2015 and 2024. Databases including PubMed, CINAHL, and Scopus were searched using keywords such as "cardiac monitoring," "intensive care," "nursing," and "telemetry." Studies focusing on both technological innovation and nursing practice implications were included.
Results: Modern cardiac monitoring technologies in ICUs include telemetry, bedside multi-parameter monitors, implantable devices, and wearable sensors. These systems offer continuous ECG monitoring, real-time data analytics, and remote access capabilities. The review found that while these innovations improve early detection of cardiac events and patient outcomes, they also pose challenges related to alarm fatigue, technical competency, and workload for nurses.
Conclusion: Cardiac monitoring technologies have significantly improved critical care delivery, but their effectiveness is closely tied to the competence and responsiveness of nursing staff. Ongoing education, system integration, and workflow redesign are necessary to mitigate the challenges and fully harness the benefits of these technologies in the ICU setting.

Key words: Cardiac monitoring, intensive care, nursing implications.
