Disease Overview：First-degree atrioventricular block（1° AV block）
First-degree atrioventricular (AV) block is a common electrocardiographic (ECG) finding characterized by prolonged PR interval (>200 ms) without interruption of impulse conduction from the atria to the ventricles. It reflects delayed conduction through the AV node—often benign and asymptomatic, particularly in young, healthy individuals or well-trained athletes—but may also signal underlying pathology such as myocarditis, Lyme disease, electrolyte disturbances, or medication effects (e.g., beta-blockers, calcium channel blockers). While typically not requiring intervention, persistent or progressive first-degree AV block warrants thorough cardiovascular evaluation—including echocardiography, Holter monitoring, and electrophysiological assessment—to rule out structural heart disease or early-stage conduction system disease.
China offers distinct advantages for international patients seeking comprehensive evaluation and management. Leading cardiovascular centers—such as Fuwai Hospital (National Center for Cardiovascular Diseases) and Shanghai Ruijin Hospital—combine deep clinical expertise in arrhythmia diagnostics with state-of-the-art equipment, including high-density mapping systems and AI-enhanced ECG interpretation platforms. Thousands of documented cases demonstrate accurate risk stratification and timely transition to advanced therapies when indicated. Treatment costs remain significantly lower than in the US or Western Europe—often 40–60% less—without compromising diagnostic rigor or clinical outcomes. As a dedicated medical tourism agency, we facilitate seamless access: coordinating appointments with certified cardiologists, verifying hospital accreditation, providing itemized, transparent pricing in advance, and delivering end-to-end support—from visa assistance and medical translation to post-consultation follow-up—all tailored to international patient needs.

Medical Treatment Guide
Treatment Options & Itemized Cost Breakdown: First-Degree Atrioventricular Block (Cardiology Department)
Non-Surgical / Conservative Management
*Indicated for asymptomatic patients with stable PR interval <300 ms, no structural heart disease, and no progression on serial ECGs.*
- •Baseline Diagnostic Workup:
- Transthoracic echocardiogram (TTE) — assess LV function, valves, wall thickness (¥450 → $63) - Holter monitoring (24-hr) — rule out intermittent higher-grade block (¥320 → $45) - Serum electrolytes (K⁺, Mg²⁺, Ca²⁺), TSH, troponin (¥180 → $25)
- •Pharmacologic Adjustment (if causative):
- •Long-term Surveillance:
Surgical / Procedural Intervention
*Not indicated for isolated first-degree AV block. Intervention is reserved only if progression to symptomatic second-/third-degree AV block or documented asystole occurs.*
- •Preoperative Evaluation (mandatory before pacemaker consideration):
- Cardiac MRI (if infiltrative/structural suspicion) (¥2,200 → $306)
- •Permanent Pacemaker Implantation (Transvenous):
- Dual-chamber (DDD) system: ¥45,000–¥65,000 ($6,260–$9,040) - Includes device, leads, fluoroscopy, anesthesia, 1-day hospitalization (Grade 3A tariff)
Special / Complex Scenarios
- •First-degree AV block with acute myocarditis or Lyme carditis:
- •Post-cardiac surgery first-degree AV block with persistent PR >300 ms + left bundle branch block:
Quick Selection Guide
- •Asymptomatic young adult (<45 y), PR 220 ms, normal echo: Conservative management only — $150–$200 initial workup, then $28/year.
- •Elderly patient (≥75 y) with PR 280 ms + hypertension + prior MI: Enhanced surveillance (biannual Holter + TTE) — $120/year, avoid procedural escalation unless progression.
- •Patient with PR >300 ms + syncope + EPS-proven His-Purkinje disease: Proceed directly to DDD pacemaker — $6,260–$9,040 (cost-effective vs. risk of sudden cardiac death).
- •Budget-constrained patient (<$500 USD): Prioritize ECG + TTE + electrolytes ($100) and eliminate offending drugs; defer Holter/EPS unless symptoms emerge.
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:
