Silent Atrial Fibrillation Often Misdiagnosed as Stress, Hong Kong Cardiologists Warn
AM730 · 1 SOURCESabout 1 hour ago2 MIN

Summary
Cardiac arrhythmia is highly prevalent in Hong Kong, with atrial fibrillation being the most common type. Many patients remain unaware of their condition as symptoms can be absent, leading them to attribute irregular heartbeats to stress or nervousness. Dr. Chan Kit, Chairman of the Hong Kong Cardiac Electrophysiology Association, emphasizes that untreated atrial fibrillation substantially elevates cardiovascular disease risk. Newer pulsed field ablation technology promises improved treatment outcomes with reduced complications.
Key Points
- Atrial fibrillation involves irregular electrical activity in the atria, causing rapid and irregular heartbeats with symptoms including palpitations, shortness of breath, chest tightness, and dizziness
- Diagnosis typically requires 24-hour or extended Holter monitoring, as standard ECGs or pulse checks may miss paroxysmal cases
- Smartwatches capable of ECG recording can help patients document irregular heartbeats for medical review
- Stroke prevention involves anticoagulants reducing risk by 60-70% in high-risk patients, with left atrial appendage closure as an alternative for those with combined bleeding risks
- Traditional thermal/cryo ablation carries higher complication risks and longer procedure times compared to newer pulsed field ablation, which reduces complications and procedure duration by half while achieving 70-80% success for paroxysmal cases
Why It Matters
With an aging population, atrial fibrillation cases are expected to rise substantially in Hong Kong. The availability of advanced pulsed field ablation offers a safer, more effective treatment option for the growing number of patients who may otherwise face life-threatening strokes or heart failure. Early diagnosis through wearable devices and appropriate medical consultation can prevent serious complications, reducing the burden on Hong Kong's healthcare system .
