A diary is given to record the day’s activities, so the doctor will know your active or resting state. The small blood pressure cuff that is connected to the monitor will automatically check the blood pressure at regular intervals (about every 30 minutes), even while sleeping.The units function poorly during strenuous activity and work best if the patient slows or stops moving. ![]() Patient diaries are encouraged so that the cause of sudden changes in blood pressure can be evaluated. Patients can start or stop recordings and they can read the displayed results if they wish. The measurement frequency can be varied, but it is usually between 20-30 minutes while awake and 30-60 minutes while sleeping. Most devices use either brachial artery microphones to detect Korotkoff sounds or cuff oscillometry where cuff pressure oscillations are detected. ABP provides a 24-hour profile, allowing assessment of clinic effects, drug effects, work influence, etc.Patients with hypertension whose nocturnal blood pressure remains high, Studies have shown that end-organ damage is more closely related to ambulatory blood pressure (ABP) than clinic blood pressure readings.To exclude the possibility of “white coat” hypertension.Ambulatory blood pressure (ABP) may be a better predictor of cardiovascular events than clinic blood pressure readings.Why use ambulatory blood pressure monitoring? It is also a useful tool for monitoring BP in patients who feel weak or who are hypotensive. Multiple readings are useful for evaluating the effectiveness of high BP treatments in patients who have commenced medication or other therapy. Patients often experience “white coat” hypertension (elevated BP in the presence of a doctor) and are wrongly diagnosed with high BP. This is because a 24 hour reading is more reliable than a simple one off reading. This trend is supported by evidence that 24-hour blood pressure profiles may be superior to isolated clinic pressures. Holter monitoring is used to determine how the heart responds to normal activity.Non-invasive ambulatory blood pressure monitoring (ABPM) is being increasingly used to assess patients with hypertension. You should continue your normal activities while wearing the monitor. This may make sleeping difficult for some people. You must keep the monitor close to your body. However, some people may need to have their chest shaved so the electrodes can stick. You will not be able to do so while you are wearing a Holter monitor. Make sure you shower or bathe before you start the test. Tell your doctor if you are allergic to any tape or other adhesives. You’ll be told how to replace the electrodes should they fall off or become loose. There is no special preparation for the test. It is very important that you accurately record your symptoms and activities so that the doctor can match them with your holter monitor findings. The doctor will look at the records and see if there have been any irregular heart rhythms. After 24 – 48 hours, you return the monitor to your doctor’s office. You should keep a diary of what activities you do while wearing the monitor. While you wear the monitor, it records your heart’s electrical activity. You carry the holter monitor in a pocket or small pouch worn around your neck or waist. How the Test is PerformedĮlectrodes (small conducting patches) are stuck onto your chest and attached to a small recording monitor. Since the recording covers a 24 hours continuous basis, holter monitoring is much more likely to detect an abnormal heart rhythm when compared to the EKG. Since it can be worn during the patient’s regular daily activities, it helps the physician correlate symptoms of dizziness, palpitations or black outs. ![]() This records various electrical activity of the cardiovascular system for at least 24 hours. heart monitor is also known as a holter monitor.
