Cardiac Monitoring Services in Irvine, California provides Holter devices and event monitors that allow medical professionals to analyze cardiovascular activity. These devices help document a patient's heart rate throughout the day. Individuals with potential heart issues can benefit from periodically checking their heart rate, as an increased or slow heart rate could indicate conditions like heart failure or bradycardia. A basic method for individuals to check their heart rate involves counting heartbeats over 15 seconds and multiplying by four to determine beats per minute. Normal resting heart rate for adults is between 60 to 100 bpm, and physical activity will cause the rate to increase while resting or waking will decrease the rate.
