KUALA LUMPUR:
Arrhythmia, or irregular heartbeat, is among the most common but often undetected heart-rhythm disorders in Malaysia. Left untreated, it can lead to serious complications such as stroke or heart failure.
According to consultant cardiologist Dr Koh Kok Wei, atrial fibrillation (AF) is the most common arrhythmia worldwide, affecting about 1% of the population. The risk is higher among individuals aged 65 and above, and in patients with conditions such as diabetes and hypertension.
