SGCMH Cardiopulmonary Department: Monitoring

24 hour and 48 hour Holter Monitoring

Holter Monitors are medical devices that are worn for either 24 or 48 hours and continuously record the heart’s electrical activity. Your provider may order a holter monitor to rule out an arrhythmia, which are problems with the rate or rhythm of the heartbeat. A holter monitor is about the size of a large deck of cards and is attached to electrodes that are worn on the chest. You cannot get your holter monitor wet, so you will not be able to bathe or shower while wearing it. You will be instructed to keep a diary of specific symptoms that you have while it is worn. The device records the information about your electrical activity and the data is stored on a memory card. Once the monitor is returned, the information is downloaded and reviewed by a physician for interpretation. You will be instructed by staff about how to wear the monitor and how to record symptoms.

Mobile Telemetry/Event Monitoring

Event Monitors/Mobile Telemetry are small medical devices that are worn for up to 30 days. The device is connected to electrodes that are worn on the chest. The monitor can automatically detect certain arrhythmias and very fast or very slow heart rates. While wearing this type of monitor, you will be instructed to record specific symptoms that you may have by pressing buttons on the equipment. The heart’s electrical data is automatically sent via cell phone to a large data center where the information is reviewed. A physician will then review the information for interpretation. You will be instructed by staff about how to wear and use the monitor, including how to apply and disconnect for showering or bathing.

24 hour Blood Pressure Monitoring

Ambulatory Blood Pressure Monitors are medical devices that are worn continuously for 24 hours. During this time, a blood pressure cuff that is worn around the upper arm inflates and records blood pressures at specified intervals. Blood pressures are taken less often during the nighttime hours. Once you return the monitor, the information is downloaded and given to your provider. You will be instructed about wearing the monitor by a staff member.
