Part MED - ANNEX IV - Medical

(6) Mobitz type 2 atrio-ventricular block
Applicants with Mobitz type 2 AV block should require full cardiological evaluation
and may be assessed as fit in the absence of distal conducting tissue disease.
(7) Complete right bundle branch block
Applicants with complete right bundle branch block should undergo cardiological
evaluation on first presentation and subsequently:
(i) Applicants with complete right bundle branch block should undergo a
cardiological evaluation on first presentation. A fit assessment may be
considered if there is no underlying pathology.
(ii) Applicants with bifascicular block may be assessed as fit with an OML after a
satisfactory cardiological evaluation. The OML may be considered for removal
if an electrophysiological study demonstrates no infra-Hissian block, or a 3-
year period of satisfactory surveillance has been completed.
(8) Complete left bundle branch block
(i) A fit assessment may be considered subject to satisfactory cardiological
evaluation and a 3-year period with an OML, and without an OML after 3 years
of surveillance and satisfactory cardiological evaluation.
(ii) Investigation of the coronary arteries is necessary for applicants over age 40.
(9) Ventricular pre-excitation
(i) Asymptomatic initial applicants with pre-excitation may be assessed as fit if
an electrophysiological study, including adequate drug-induced autonomic
stimulation reveals no inducible re-entry tachycardia and the existence of
multiple pathways is excluded.
(ii) Asymptomatic applicants with pre-excitation may be assessed as fit at
revalidation with limitation(s) as appropriate. Limitations may not be
necessary if an electrophysiological study, including adequate drug-induced
autonomic stimulation, reveals no inducible re-entry tachycardia and the
existence of multiple accessory pathways is excluded.
(10) Pacemaker
Applicants with a subendocardial pacemaker should be assessed as unfit. A fit
assessment with an OML may be considered at revalidation no sooner than 3
months after insertion provided:
(i) there is no other disqualifying condition;
(ii) a bipolar lead system, programmed in bipolar mode without automatic mode
change has been used;
(iii) the applicant is not pacemaker dependent; and;
(iv) the applicant has a follow-up at least every 12 months, including a pacemaker
check.
(11) QT prolongation
Applicants with asymptomatic QT prolongation may be assessed as fit with an OML
subject to satisfactory cardiological evaluation.
(12) Brugada pattern on electrocardiography
Applicants with a Brugada pattern Type 1 should be assessed as unfit. Applicants
with Type 2 or Type 3 may be assessed as fit, with limitations as appropriate,
subject to satisfactory cardiological evaluation.
MED.B.010 AMC2 Cardiovascular system
(a) Examination
Exercise electrocardiography
An exercise ECG when required as part of a cardiovascular assessment should be
symptomlimited and completed to a minimum of Bruce Stage IV or equivalent.
(b) General
(1) Cardiovascular risk factor assessment
Applicants with an accumulation of risk factors (smoking, family history, lipid
abnormalities, hypertension, etc.) should undergo a cardiovascular evaluation by
the AeMC or AME.
(2) Cardiovascular assessment
Reporting of resting and exercise electrocardiograms should be by the AME or an
accredited specialist.
(c) Peripheral arterial disease
A fit assessment may be considered for an applicant with peripheral arterial disease, or
after surgery for peripheral arterial disease, provided there is no significant functional
impairment, any vascular risk factors have been reduced to an appropriate level, the
applicant is receiving acceptable secondary prevention treatment, and there is no
evidence of myocardial ischaemia.
(d) Aortic aneurysm
(1) Applicants with an aneurysm of the infra-renal abdominal aorta of less than 5 cm in
diameter may be assessed as fit, subject to satisfactory cardiological evaluation.
Regular cardiological evaluations should be carried out.
(2) Applicants with an aneurysm of the thoracic or supra-renal abdominal aorta
aneurysm, of less than 5 cm in diameter may be assessed as fit with an ORL or
OSL, subject to satisfactory cardiological evaluation. Regular follow-up should be
carried out.
