Disease Overview：Second-degree atrioventricular block（2° AV block）
Second-degree atrioventricular (AV) block is a cardiac conduction disorder characterized by intermittent failure of electrical impulses to propagate from the atria to the ventricles. It is classified into two main types: Mobitz Type I (Wenckebach), typically involving progressive PR interval prolongation before a dropped beat and often benign, and Mobitz Type II, marked by sudden non-conducted P waves without preceding PR changes—indicating more serious infranodal disease and higher risk of progression to complete heart block. Symptoms range from asymptomatic findings on routine ECG to dizziness, syncope, fatigue, or presyncope, particularly with Type II or high-grade variants. Diagnosis relies on electrocardiography, often supplemented by Holter monitoring, electrophysiological studies, and echocardiography to assess structural heart disease and guide management. Treatment depends on type, symptoms, and underlying etiology: asymptomatic Mobitz Type I may require only observation, while symptomatic cases or Mobitz Type II generally necessitate permanent pacemaker implantation—a Class I indication per ACC/AHA guidelines.
China offers distinct advantages for international patients seeking care for second-degree AV block. Leading cardiovascular centers—such as Fu Wai Hospital (National Center for Cardiovascular Diseases) and Shanghai Ruijin Hospital—combine deep expertise in electrophysiology with state-of-the-art infrastructure, including 3D electroanatomic mapping systems, MRI-compatible pacemakers, and real-time intraoperative pacing assessment. These institutions report >99% procedural success rates for transvenous and subcutaneous pacemaker implantation, with robust long-term follow-up protocols. Crucially, costs for comprehensive evaluation and device implantation are typically 40–60% lower than in the US or Western Europe, without compromising clinical standards or regulatory oversight—devices meet CE and NMPA certification, and all procedures adhere to ISO 9001 and JCI-aligned quality frameworks. As a dedicated medical tourism agency, we facilitate seamless access to these resources: coordinating appointments with certified electrophysiologists, verifying hospital accreditation, providing itemized, transparent pricing in advance, and offering end-to-end support—from visa assistance and medical translation to post-procedure recovery coordination and remote follow-up linkage.

Medical Treatment Guide
Treatment Options & Itemized Cost Breakdown: Second-Degree Atrioventricular Block (Cardiology Department)
Non-Surgical / Conservative Management
*Indicated for asymptomatic Mobitz I (Wenckebach), stable hemodynamics, no structural heart disease, and reversible causes (e.g., drug-induced, electrolyte imbalance).*
- •Electrolyte correction & medication adjustment: $45–$120 (IV potassium/magnesium infusion + ECG monitoring × 24h; drug discontinuation protocol)
- •Ambulatory ECG monitoring (72-h Holter): $85–$135
- •Baseline labs: $65 (serum K⁺, Mg²⁺, Ca²⁺, creatinine, TSH, troponin I)
- •Echocardiogram (TTE): $140–$210
- •Follow-up outpatient visits (3-month cycle): $35–$55/visit
Surgical / Procedural Intervention
*Indicated for symptomatic Mobitz II, advanced AV block, wide QRS complex, or progression on Holter.*
- •Preoperative workup: $290–$410
- Cardiac MRI (if suspected infiltrative disease): $380 - Electrophysiology study (EPS): $420–$650
- •Permanent dual-chamber pacemaker implantation (DDD): $4,800–$7,200
- •Leadless pacemaker (Micra AV): $12,500–$15,800
Special/Complex Condition Management
- •Acute myocardial infarction–associated Mobitz II: Urgent revascularization + temporary pacing → permanent pacing: $8,900–$13,400 total (PCI + pacemaker)
- •Lyme carditis–related block: IV ceftriaxone × 14 days ($220) + observation; pacing only if persistent: $5,100–$7,500
- •Post-cardiac surgery AV block: Temporary epicardial pacing ($380/day) + delayed permanent implant at 7–14 days: $5,300–$7,800
Quick Selection Guide
- •Asymptomatic elderly (>75 y), low budget, no comorbidities: Conservative monitoring — total 3-month cost: $280–$420
- •Symptomatic Mobitz II, age 45–65, no renal/hepatic disease: Standard DDD pacemaker — $5,100–$7,600 (optimal balance of efficacy, durability, cost)
- •Young athlete with Lyme seropositivity & transient block: Antibiotics + Holter surveillance — $320–$490, avoid device unless recurrent
- •High-bleeding-risk patient (e.g., anticoagulated AF, CKD stage 4): Leadless pacemaker — $12,800–$16,100, eliminates lead-related complications
- •Acute STEMI + new Mobitz II: Immediate PCI + urgent pacing — $9,200–$13,900, prioritizes ischemia resolution first
Pricing & Service Differences: International / VIP Dept vs. Regular Clinic
International Medical Services (IMS / VIP Departments) at Grade-3A public hospitals and private international clinics operate under self-regulated VIP fee schedules. Fees are higher than standard public clinics (which are subsidized solely for domestic citizens and do not accept overseas insurances). In exchange, international patients receive 6 exclusive medical privileges:
