What to Know About ECGs and Early Heart Care?

This February, Heart Month is a reminder to put your heart first — not after a health scare, but long before symptoms appear. Prevention, not reaction, is what truly saves lives. Heart disease often develops silently, with many people feeling well while underlying issues progress unnoticed. Routine screening helps detect problems early, when lifestyle changes and treatment are most effective. The National Health Fund (NHF) is therefore encouraging early screening through electrocardiograms (ECGs), supported by an NHF subsidy that improves access to this important test.

Why ECGs Matter

An ECG is a simple, non-invasive procedure that records the heart’s electrical activity. It provides valuable insight into heart rhythm and overall function. According to Dr. TahiraRedwood, interventional cardiologist at the National Chest Hospital, ECGs are critical screening tools. “A person may feel perfectly healthy yet still have rhythm disturbances, early heart muscle strain, or even signs of past minor damage. An ECG offers clinicians an objective snapshot of the heart and can detect abnormalities before symptoms arise”.

What an ECG Can Detect

ECGs can help identify abnormal heart rhythms, early signs of a heart attack or evidence of a previous one, enlarged heart chambers, electrical conduction problems, and the effects of certain medications or electrolyte imbalances. While the test does not diagnose every heart condition, it can signal when further evaluation is necessary.

There is no fixed age to begin ECG screening; however, heart health should be a priority by your 30s. Earlier testing may be warranted if you have risk factors such as hypertension, diabetes, obesity, or a strong family history of heart disease. Establishing a baseline ECG in adulthood can also be useful for future comparison.

Knowing your numbers is equally important. Regularly monitor your blood pressure, blood sugar, and cholesterol. Pair this with manageable daily habits, such as taking a 30-minute walk, reducing salt intake, or choosing water over sugary drinks. Small, consistent actions make a meaningful difference.

NHFCard Support

The NHF provides a subsidy to reduce the cost of ECG testing. To benefit, ensure your NHFCard details are current, obtain a doctor’s referral, and use your card at a participating medical office or diagnostic centre. This Heart Month, take proactive steps to protect your heart.
