Electrocardiograms (ECGs) play a crucial role in health monitoring technology by providing a graphical representation of the electrical activity of the heart. They help detect irregularities in heart rhythm, diagnose heart diseases, and assess overall cardiovascular health. ECG devices are vital for both clinical settings and wearable technology, enabling continuous health monitoring. By analyzing ECG data, healthcare professionals can proactively identify potential health issues and provide timely interventions, improving patient outcomes and preventive care.
