Cardiovascular monitoring is the process of observing and measuring the heart's activity and blood flow to ensure it is functioning properly. This can involve using devices like electrocardiograms (ECGs) to track the heart's electrical signals, or blood pressure monitors to check how well blood is circulating throughout the body. Healthcare professionals use cardiovascular monitoring to detect any irregularities or potential problems, such as arrhythmias or heart attacks. By keeping a close eye on these vital signs, doctors can make informed decisions about treatment and help patients maintain a healthy heart.
