DrGo, together with Roche Diagnostics (Hong Kong) Limited, FibriCheck and The Hong Kong Society for Rehabilitation (“HKSR”), have launched this “Atrial Fibrillation Tele-Screening Programme (“AF-SEEN Programme” / “Programme”), with an aim to raising awareness of stroke risk caused by AF among Hong Kongers. This Programme enables participants to perform AF screening using FibriCheck on their smartphones.
This Programme will offer free access to the in-app FibriCheck feature to up to 100,000 DrGo users in Hong Kong for 14 days, during which period participants are recommended to check their heart rhythm twice a day (in the morning and at dusk), or when they experience possible symptoms of AF. If the screening shows that there is a possibility of AF, relevant participants will be contacted by HKSR for following-up. Participants will receive a full FibriCheck report on the DrGo App after the 14-day period.

Data collected from the Programme will be used in a study by Dr. Chan Ngai Yin for the possibility of tele-screening of AF in Hong Kong, which could potentially help to reduce the burden of the Hong Kong public healthcare system.
If abnormal heart rhythm is detected and symptoms / discomforts persist, participants are advised to seek immediate medical attention as needed. FibriCheck measurements and any analysis available under the Programme are not a diagnosis and do not replace medical advice. Participants are advised to seek professional medical assistance if participants are, or believe that they are, suffering from any medical problem.

HKSR follow-up
HKSR will contact relevant participants for following-up (see the 2nd phase).

2nd phase:
Up to 1,500 participants in total
(with additional 14-day free access to FibriCheck, if applicable)
HKSR follow-up
  • HKSR will contact up to 1,000 participants who have been detected with possible AF with no AF history and invite them to the closest Community Rehabilitation Network (“CRN”) Center of HKSR for further AF confirmatory tests.
  • One AliveCor 6L electrocardiogram (ECG) device (“AliveCor”) will be provided to participants for heart rhythm measurements at home.
Measurement with AliveCor
  • Participants are recommended to measure their heart rhythm on AliveCor at least twice a day, or when they experience possible symptoms of AF (e.g. heart palpitations or shortness of breath).
Additional 14-day FibriCheck access
  • Participants will be granted an additional 14-day free access to FibriCheck, during which period they are recommended to check their heart rhythm on FibriCheck on the DrGo App daily, in conjunction with the AliveCor use.
Non-AF participants
  • To further verify the accuracy of FibriCheck on the DrGo App, HKSR will contact up to 500 participants who were screened AF negative during the initial 14-day use for following-up. These participants will be invited to the closest CRN Centre for following-up in the same way as AF-positive participants as mentioned above.
Return of AliveCor
  • Participants are required to return AliveCor in clean and good working condition to a CRN Centre or as directed by HKSR within one week after the said second 14-day period.
Result analysis
  • Upon return of AliveCor, HKSR will extract the ECG data and then send to doctors for interpretation and reporting together with the FibriCheck report.
HKSR further follow-up
  • HKSR will contact relevant AF positive participants 6 months after the analysis to try to understand the health-seeking behaviour, prescription of oral anticoagulants and compliance to medications of participants.

What is AF?
AF is a common heart rhythm disorder. Electrical activities are abnormally fast in the atria and the frequency of electrical impulses can be over 300 per minute. This leads to abnormally fast and irregular electrical activation in the ventricles and felt by the patients as palpitations. With the frequent electrical activities of the atria, there is no effective atrial contraction and patients are prone to develop stroke.
What are the risk factors for AF?
Risk factors for AF include older age, hypertension, coronary artery disease, diabetes, obesity, chronic lung disease, heart failure, valvular heart disease and obstructive sleep apnoea.
What are the consequences of AF?
Although it is not immediately life-threatening for patients with AF, complications include stroke and heart failure may occur in the long-run. On the other hand, mortality is also increased in patients with AF.
When do I see a doctor for AF consultation?
As soon as you notice the symptoms of AF, contact your doctor. Even if your symptoms go away, it’s still important to have an assessment by your doctor.
What treatments should I expect when diagnosed with AF?
Many patients with AF are at high risk of developing stroke. Blood thinning medications or medically named as oral anticoagulants are highly effective in reducing the risk for stroke. Other medications may be given for controlling of heart rate and heart rhythm. Discuss with your doctors for the most appropriate treatment approach.
I am diagnosed with AF but do not encounter any AF symptoms, am I still at risk for stroke?
Yes! Many people with AF have no symptom but they are still at risk of developing stroke. Blood thinning medications or medically named oral anticoagulants are highly effective in reducing the risk of stroke even in patients with asymptomatic AF.
Does having AF mean I need to wear a medical alert bracelet or carry a card in my wallet?
In any emergency, having a patient’s medical history is helpful. Be sure to write down the medication and dose. If you’re taking oral anticoagulant medications (blood thinners), consider wearing a medical alert bracelet or carrying a wallet card so that healthcare professionals know how to best care for you when an emergency occurs.
Can I tell when I’m going to have an episode of AF?
Common triggers for AF include: caffeine, stress or anxiety, poor sleep and excessive alcohol.
Am I able to have exercise or sex?
Yes, as long as you’re cleared by your doctor, you can perform normal activities of daily living that you can tolerate.
Can I drive my car?
Most people with AF can but check with your doctor. Some people may experience dizziness or fainting with their AF episodes.
Is AF curable or is it a permanent condition?
We don’t usually say that AF is curable.
Can I die from an episode of AF?
AF is in general not immediately life-threatening. However, complication like stroke arising from AF can be life-threatening. Therefore, the most important thing you should do is work with your doctor or other health care professionals to make sure you’re doing all you can to prevent complications that could occur as a result of AF.
