Understanding the specialty
When should you see a cardiac electrophysiologist?
A cardiac electrophysiologist focuses on the heart’s electrical system and disorders that affect its rhythm. A specialist review may help clarify the diagnosis, understand why symptoms recur, and decide whether monitoring, medication, a procedure, or another approach should be considered.
People are often referred after a diagnosis of atrial fibrillation, recurrent rapid or irregular heartbeat, unexplained palpitations, supraventricular tachycardia, symptoms despite medication, or a recommendation to discuss catheter ablation.
Areas of clinical focus
Heart rhythm conditions and electrophysiology care
Each recommendation begins with the exact rhythm diagnosis and the individual patient’s clinical situation.
Other cardiac arrhythmias
Specialist evaluation of abnormal heart rhythms and recurrent rhythm disturbances.
Cardiac electrophysiology
Assessment focused on the electrical activity and rhythm of the heart.
Catheter ablation
Specialist assessment and catheter-based treatment for appropriate patients with certain arrhythmias.
Complex or recurrent arrhythmia
Review when symptoms or abnormal rhythms persist or return after previous treatment.
Specialist perspective
Experience focused on complex heart rhythm disorders
The first question is not simply which procedure to perform. It is understanding the rhythm problem clearly and determining which treatment approach is appropriate for the individual patient.
Dr. Ouyang is an invited arrhythmia specialist at Shanghai SinoUnited Hospital. His clinical and academic career has centered on complex cardiac electrophysiology, including catheter ablation for atrial fibrillation and difficult atrial and ventricular arrhythmias.
For patients with a complex or recurrent rhythm disorder, specialist-level evaluation can help connect symptoms, previous ECG findings, medication history, and earlier procedures before the next step is planned.
After medical and cardiology training in China, including postgraduate study at Fuwai Hospital, he moved to Hamburg in 1995 for advanced electrophysiology training and clinical work. His professional background includes leading the Clinical Electrophysiology Laboratory at Asklepios Klinik St. Georg, one of Europe’s high-volume centers for complex ablation.

Professional record
Clinical leadership shaped by arrhythmia research
Dr. Ouyang’s work has examined tachyarrhythmia mechanisms and the ablation of complex atrial and ventricular arrhythmias. Major themes include complete pulmonary vein isolation for atrial fibrillation, verapamil-sensitive left ventricular tachycardia, arrhythmias arising from the aortic sinuses and epicardial ventricular tachycardia.
He has published more than 220 manuscripts and papers, contributing to the clinical literature on atrial fibrillation, catheter technology and pulmonary vein isolation.
Atrial fibrillation
Specialist care for atrial fibrillation
Atrial fibrillation, often called AFib, is an irregular heart rhythm that begins in the upper chambers of the heart. Some people notice palpitations, fatigue, shortness of breath, or reduced exercise tolerance; others have few or no obvious symptoms.
Proper assessment matters because symptoms, rhythm patterns, other health conditions, and treatment goals differ between patients. Depending on the case, care may involve monitoring, medication, management of relevant risk factors, or a procedure.
Catheter ablation may be considered for selected patients, but it is not automatically the right choice for everyone. A specialist consultation is used to review the diagnosis, prior treatment, potential benefits, and individual risks.

Understanding catheter ablation for heart rhythm disorders
Catheter ablation is a minimally invasive procedure used for certain heart rhythm disorders. Thin catheters are guided through blood vessels to the heart, where carefully selected areas involved in abnormal electrical signals can be treated.
Whether ablation is appropriate depends on the exact diagnosis and the individual clinical situation. Evaluation may include a detailed medical history, ECGs and other rhythm recordings, medication history, imaging, and reports from earlier procedures.

- 04
Follow-up
Care is coordinated according to the treatment plan and the patient’s clinical needs.
Shanghai SinoUnited Hospital
Specialist heart care in the centre of Shanghai
Consultations, diagnostic work and treatment planning are coordinated through Shanghai SinoUnited Hospital, with support for patients arriving from across China and abroad.
International patient support
Coming to Shanghai for specialist heart care?
Patients outside Shanghai can make an initial inquiry and ask how to transfer available medical records before travel. The SinoUnited team can coordinate the appointment, pre-arrival communication, navigation of the care process, and follow-up planning according to the case.
Do not send sensitive medical files by ordinary email until the team provides secure transfer instructions.Frequently asked questions
Questions about heart rhythm care
General information to help you prepare for a specialist consultation.
What does a cardiac electrophysiologist treat?
A cardiac electrophysiologist evaluates and treats disorders of the heart’s electrical system, including atrial fibrillation and other abnormal heart rhythms.
When should I see an electrophysiologist instead of a general cardiologist?
A general cardiologist may refer you when a rhythm disorder needs more focused evaluation, symptoms recur despite treatment, or catheter ablation is being considered.
Does Dr. Feifan Ouyang treat atrial fibrillation?
Yes. Dr. Ouyang’s clinical focus includes atrial fibrillation and catheter ablation for appropriate patients.
What is catheter ablation?
It is a minimally invasive procedure that targets selected heart tissue involved in abnormal electrical signals. Suitability depends on the diagnosis and individual clinical situation.
Is catheter ablation appropriate for everyone with atrial fibrillation?
No. Monitoring, medication, risk-factor management, procedures, or a combination may be considered. A specialist assessment is needed to discuss appropriate options.
Can international patients request a consultation?
Yes. International patients may contact SinoUnited to ask about a consultation and the process for sharing records before a visit.
What medical records should I prepare?
Useful records may include ECGs or rhythm-monitoring reports, imaging, procedure reports, current and previous medications, and a concise medical history.
Where does Dr. Feifan Ouyang see patients in Shanghai?
