Section 4: Cardiovascular Diseases

4.2c. Heart Block

Syncope is the primary symptom that places the driver with heart block at-risk. The syncopal symptoms are due to brady arrhythmias secondary to structural conduction system disease. Cardiac pacing is highly effective for individuals with heart block (Miles, 1997).

Recommendations from the CCS Consensus Conference (1996) for private drivers with heart block are:

  1. No restriction for private drivers with:
    a) Isolated first-degree AV block
    b) Isolated right-bundle branch block
    c) Isolated left-anterior fascicular block
    d) Isolated left-posterior fascicular block

  2. No restriction for private drivers with no associated cerebral ischemia and:
    a) Left bundle branch block
    b) Bifascicular block
    c) Mobitz Type I AV block
    d) First-degree AV block and bifascicular block

  3. Disqualification for private drivers with:
    a) Mobitz Type II AV block
    b) Trifascicular block
    c) First degree AV block and bifascicular block

  4. No restriction for congenital third degree AV block for private drivers with
    a) no associated cerebral ischemia
