Heart Tests & Monitoring

Non-invasive tests that assess heart function and rhythm

12-Lead ECG with Cardiology Report

A 12-lead ECG records the electrical activity of the heart. It can identify rhythm disturbances, evidence of previous heart attacks, or other electrical abnormalities.

WHAT TO EXPECT

Electrodes are placed on your chest, arms, and legs. The test takes only a few minutes. The ECG is formally reviewed and reported by a cardiologist.

Holter Monitoring (24–48 hours)

Holter monitoring continuously records your heart rhythm over one to two days. It is useful for detecting intermittent rhythm problems that may not appear during a brief ECG.

WHAT TO EXPECT

Small electrodes are placed on your chest and connected to a portable recording device worn under clothing. You continue your normal daily activities while the monitor records your heart rhythm. The device is returned after the monitoring period for specialist analysis.

Event Recording (up to 1 month)

An event recorder monitors heart rhythm over a longer period, helping diagnose infrequent symptoms such as palpitations, dizziness, or fainting.

WHAT TO EXPECT

You will wear a small recording device for up to one month. The device records your heart rhythm either automatically or when you activate it during symptoms. Recorded events are reviewed by a cardiologist.

24-hour Ambulatory Blood

This test measures blood pressure repeatedly over a full day and night, providing a more accurate picture than a single clinic reading.

WHAT TO EXPECT

A blood pressure cuff is worn on your upper arm and connected to a small portable monitor. The cuff inflates automatically at regular intervals during the day and night. You return the device the following day for analysis.

Treadmill Exercise Testing

A treadmill exercise test looks at how your heart performs during physical activity. It helps identify reduced blood flow to the heart, exercise-related chest pain, abnormal heart rhythms, or unexplained breathlessness.

WHAT TO EXPECT

Small monitoring electrodes are placed on your chest and a blood pressure cuff is applied. You will walk on a treadmill that gradually increases in speed and incline. Your heart rhythm, heart rate, and blood pressure are monitored throughout. The test usually takes 20–30 minutes and can be stopped at any time if you feel unwell.

Signal-Averaged ECG

This is a specialised, non invasive diagnostic test that provides a detailed look at the heart's electrical conduction system, often identifying minute electrical signals that a standard electrocardiogram (ECG) cannot detect

WHAT TO EXPECT

The test takes approximately 10 to 20 minutes. It is non-invasive, painless, and does not require hospitalization.

You will be asked to lie still for 10–20 minutes, as movement can introduce noise that interferes with the measurement.
