Definition
A cardiac monitor is a medical device that continuously tracks a patient's heart activity. It displays information like heart rate, rhythm, and electrical activity (ECG). Think of it as a heart's personal DJ, constantly monitoring the beats. It uses sensors attached to the patient's body to detect and record these signals. Doctors and nurses use cardiac monitors to detect abnormalities and provide timely treatment. It's a critical tool in hospitals and emergency rooms, providing constant updates on the most vital organ.
