Wireless ECG
A Holter monitor is an ECG recording done over a period of 24 or more hours. Electrodes are attached to the patient’s chest and connected to a Digital Holter Recorder by lead wires. The patient goes about his/her usual daily activities (except for activities such as taking a shower, swimming, or any activity causing an excessive amount of sweating which would cause the electrodes to become loose or fall off) during this procedure. There are 2 types of Holter monitoring:
Continuous recording – the ECG is recorded continuously during the entire testing period.
Event monitor, or loop recording – the ECG is recorded only when the patient starts the recording on the Event Recorder or Loop Recorder, when symptoms are felt.
Holter monitoring may be done when arrhythmia is suspected but not seen on a resting or signal-average ECG, since arrhythmias may be transient in nature and not seen during the shorter recording times of the resting or signal-averaged ECG.
Also called: 24 hour ECG
What is an ambulatory blood pressure monitor or holter blood pressure monitor?
It is a small device, about the size of a portable radio. Typically it is worn on a belt. The blood pressure cuff on the monitor can be worn under your clothes without anyone seeing it.
This machine lets your doctor find out what your blood pressure was every 20 to 30 minutes of a day. The information collected by this machine can help you and your doctor see if your blood pressure treatment is working.
