Professor Hua Wei: Cardiac Pacing, ICD, and Heart Failure Device Specialist
Professor Hua Wei is a senior cardiologist, professor, doctoral supervisor, and deputy director of the Arrhythmia Center at Fuwai Hospital in Beijing. His clinical and academic work focuses on pacemakers, implantable cardioverter-defibrillators, cardiac resynchronization therapy, left bundle branch area pacing, bradycardia, ventricular arrhythmias, and device treatment for heart failure.
Clinical and Academic Focus
- pacemaker implantation for slow heart rhythms;
- implantable cardioverter-defibrillators;
- cardiac resynchronization therapy;
- CRT-D and advanced heart-failure devices;
- left bundle branch area pacing;
- ventricular arrhythmia and sudden-death prevention;
- device upgrades, revisions, and lead management;
- device infection and malfunction assessment; and
- second opinions before cardiac-device treatment.
Pacemakers
A pacemaker treats selected slow heart rhythms and conduction disorders by delivering electrical impulses when the heartbeat is too slow or unreliable. Common indications include symptomatic sinus-node dysfunction and advanced atrioventricular block.
Device selection depends on the rhythm problem, heart function, anticipated pacing burden, atrial rhythm, venous anatomy, age, and other medical conditions. Not every slow pulse requires implantation.
Implantable Cardioverter-Defibrillators
An implantable cardioverter-defibrillator, or ICD, monitors heart rhythm and can deliver pacing or a shock to stop dangerous ventricular tachycardia or fibrillation.
An ICD may be recommended after cardiac arrest or for selected high-risk patients with cardiomyopathy and severely reduced heart function. The decision should consider expected survival, competing disease, arrhythmia risk, device complications, and patient preferences.
Cardiac Resynchronization Therapy
Cardiac resynchronization therapy, or CRT, coordinates contraction of the heart’s ventricles in selected patients with heart failure and electrical conduction delay. CRT-P provides pacing, while CRT-D also includes defibrillation capability.
Potential benefits include improved symptoms, heart function, quality of life, and survival. Response varies, and some patients do not improve despite technically successful implantation.
Left Bundle Branch Area Pacing
Left bundle branch area pacing aims to activate the heart’s natural conduction system more physiologically than conventional right-ventricular pacing. It may be considered for bradycardia, prevention of pacing-related dysfunction, or cardiac resynchronization in selected patients.
Professor Hua has contributed to clinical research comparing left bundle branch area pacing with conventional biventricular pacing. Long-term suitability depends on anatomy, indication, operator experience, lead performance, and current evidence.
Device Upgrade and Revision
Patients with an existing pacemaker may need an upgrade if heart function worsens or pacing causes dyssynchrony. Revision may also be required for lead failure, battery depletion, venous obstruction, infection, discomfort, or inadequate therapy.
Lead extraction can carry significant risks and should be planned at an experienced center with surgical backup when needed.
Device Infection
Redness, swelling, drainage, fever, bloodstream infection, or exposed hardware may indicate a device infection. Treatment often requires complete system removal plus antimicrobial therapy rather than antibiotics alone.
Suspected infection requires prompt local assessment and should not wait for international travel.
Living With a Cardiac Device
Follow-up checks battery status, lead performance, pacing percentage, arrhythmia episodes, delivered therapies, and symptoms. Patients should carry device identification and discuss MRI, surgery, radiation therapy, electrical equipment, and travel security with their device team.
Who May Consider a Consultation?
- patients with symptomatic bradycardia or conduction block;
- patients being evaluated for an ICD after cardiac arrest or cardiomyopathy;
- patients with heart failure considering CRT or CRT-D;
- patients comparing biventricular and conduction-system pacing;
- patients whose heart function declined after chronic pacing;
- patients with recurrent ICD shocks;
- patients with suspected lead failure, device infection, or venous obstruction; or
- patients seeking a second opinion before device upgrade or extraction.
Medical Records to Prepare
- a concise cardiac symptom and treatment timeline;
- 12-lead ECGs and prolonged rhythm-monitoring reports;
- echocardiography and cardiac MRI in original format;
- coronary and heart-failure evaluations;
- device implant reports with manufacturer, model, lead type, and location;
- recent device interrogation and remote-monitoring reports;
- records of shocks, fainting, infection, or lead alarms;
- chest X-rays and venous imaging when relevant;
- a complete medication list; and
- a clear list of functional goals and device questions.
Planning an International Consultation
Fainting with a slow rhythm, repeated ICD shocks, severe breathlessness, fever with device-pocket changes, or exposed hardware requires immediate local assessment.
Stable patients should confirm whether ECGs, imaging, and device data can be reviewed. Remote medical-record review requires physician authorization. Final device eligibility and programming usually require in-person electrophysiology assessment and confirmation of equipment compatibility.
How CMCS Can Assist
CMCS – China Medical Concierge Shanghai is an independent medical concierge and health management company, not a hospital. We assist international patients with organizing and translating cardiology and device records, identifying an appropriate specialist, requesting appointment availability, arranging interpretation, and planning medical travel in China.
Access to Professor Hua, remote review, implantation, revision, extraction, or a particular device is subject to doctor and hospital approval. CMCS does not guarantee appointments, procedure eligibility, device compatibility, or clinical outcomes.
