Cardiac Monitoring

Continuous monitoring of heart activity


Cardiac monitoring refers to continuous monitoring of the heart activity, generally by electrocardiography, with assessment of the patient’s condition relative to his or her cardiac rhythm. Three common methods for monitoring heart activity are:


Some digital patient monitors include a defibrillator. These usually have the capabilities of an ICU monitor and manual (and usually semi-automatic AED) defibrillation capability. These are useful for EMS services, who need a compact monitor and defibrillator, and for inter- or intra-facility patient transport.

Long-term ambulatory monitors

Cardiac event monitors are considered manual or automatic. Automatic ECG event monitors can measure the patient's ECG and record abnormal events without patient intervention. Manual ECG event recorders require the patient to record an event by activating the device. Implantable loop recorders are a third option that offer automatic and manual abilities.

Heart rate monitoring

Heart rate monitoring can be performed as part of electrocardiography or measured with specific heart rate monitors. These are commonly used during physical activity.

Heart rate monitoring

Monitoring of the heart rate can be performed as part of electrocardiography, but it can also be measured conveniently with specific heart rate monitors. Such heart rate monitors are largely used by performers of various types of physical exercise.
