Cardiac Monitoring Services provides devices that allow individuals to monitor their heart rate and identify potential circulatory system defects. Checking one's pulse is important for maintaining health, as increases in heart rate can foreshadow serious health conditions, even if the changes are not dramatic. The most common way to check one's pulse is by placing two fingers on the radial artery on the thumb side of the wrist and counting the heartbeats over 15 seconds, then multiplying that number by four to determine the heart rate.
