Holter Monitoring: A Window into Your Heart's Activity

At Subang Jaya Medical Centre's Heart, Vascular, and Thoracic Department, we understand the importance of continuous monitoring to assess your heart's activity accurately. Holter Monitoring is a non-invasive diagnostic test that provides valuable insights into your heart's electrical activity over an extended period.

During Holter Monitoring, you will wear a small, portable device called a Holter monitor. This device is connected to electrodes placed on your chest, and it records your heart's electrical signals continuously for a designated period, typically 24 to 48 hours. The monitor captures data on your heart's activity throughout your daily routine, including during rest, sleep, and physical activities.

1. Detecting Arrhythmias: Holter Monitoring allows our cardiologists to identify and analyse abnormal heart rhythms (arrhythmias) that may not be captured during a standard ECG. It provides a more comprehensive assessment of your heart's electrical activity, helping diagnose conditions such as atrial fibrillation, ventricular arrhythmias, or pauses in the heartbeat.

2. Correlating Symptoms and Events: If you experience symptoms such as palpitations, dizziness, or fainting spells, Holter Monitoring provides a crucial opportunity to correlate these symptoms with your heart's electrical activity. By analysing the recorded data, our cardiologists can determine if there is an underlying heart rhythm disorder causing your symptoms.

3. Assessing Treatment Effectiveness: For patients with known arrhythmias or those undergoing treatment for heart conditions, Holter Monitoring helps evaluate the effectiveness of medications, interventions, or lifestyle modifications. It provides valuable data on the frequency and duration of arrhythmias, guiding adjustments to treatment plans as necessary.
