24 ABPM

24-Hour Ambulatory Blood Pressure Monitoring (ABPM)

24-hour ABPM is a method designed to measure your blood pressure as you move around living your normal daily life over 24 hours. It uses a small digital blood pressure machine that is attached to a belt around your body and which is connected to a cuff around your upper arm. It is small enough so that you can go about your normal daily life and even sleep with it on.

 

Why should I need a 24-hour BP monitoring?

By measuring your blood pressure at regular intervals over 24 hours, your doctor will be able to obtain a clear idea of how your blood pressure changes throughout the day.

 

Your doctor may suggest this test because:


  • They may want to find out if your high blood pressure readings in the clinic are much higher than they are away from the clinic (called the “white-coat effect”).
  • They may want to know how effective your medicines are controlling your blood pressure throughout the day.
  • They may want to see if your blood pressure stays high at night. If so, your medicines may need to be adjusted or changed.

24-Hours Holter monitor

A Holter monitor is a battery-operated portable device that measures and tape records your heart’s activity (ECG) continuously for 24 hours. The device is the size of a small camera. It has wires with electrodes that attach to your skin. It records your ECG for 24 hours as you go about your daily activities, hence, it is also known as ambulatory electrocardiography.


As the recording covers 24 hours, on a continuous basis, Holter monitoring is much more likely to spot an abnormal heart rhythm when compared to the ECG which lasts less than a minute. It can also help evaluate your ECG during episode of chest pain, during which time there may be changes in the ECG tracing that suggests lack of blood or oxygen supplies to your heart.


Since it can be worn during regular daily activities, it helps your doctor to correlate symptoms of dizziness, palpitation (a sensation of fast or irregular heart rhythm) or black outs.


A diary or log is provided so that the patient can record activity (walking, jogging , upset, eating, etc.) and symptoms (skipped heart beats, palpitation, chest discomfort, dizziness, etc.) together with the time.
