9               Factors that must exist
At least one of the following factors must as a minimum exist before it can be said that a reasonable hypothesis has been raised connecting heart block or death from heart block with the circumstances of a person's relevant service:
(1)          having ischaemic heart disease at the time of the clinical onset of heart block;
(2)          having pulmonary thromboembolism within the 7 days before the clinical onset of heart block;
(3)          having infiltration of the myocardium due to an infiltrative disease from the specified list of infiltrative diseases at the time of the clinical onset of heart block;
Note: specified list of infiltrative diseases is defined in the Schedule 1 - Dictionary.
(4)          having cardiomyopathy at the time of the clinical onset of heart block;
(5)          having a benign or malignant neoplasm involving the heart before the clinical onset of heart block;
            Note: A neoplasm involving the heart can be primary or metastatic. An example of a primary neoplasm involving the heart is cardiac lymphoma.
(6)          having a lesion which compresses the atrioventricular node, bundle of His or the bundle branches of the heart at the time of the clinical onset of heart block;
            Note: Examples of lesions which can compress the atrioventricular node, bundle of His or the bundle branches of the heart include a paraoeseophageal hiatus hernia, a thoracic aortic aneurysm and a haematoma.
(7)          having non-infectious myocarditis at the time of the clinical onset of heart block;
Note 1: Non-infectious myocarditis can be acute or chronic.
            Note 2: Non-infectious myocarditis can be of autoimmune, infiltrative or immunological origin. Examples of causes of non-infectious myocarditis include immune checkpoint inhibitor therapy and giant cell myocarditis.
(8)          having viral myocarditis at the time of the clinical onset of heart block;
Note 1: Viral myocarditis can be acute or chronic.
            Note 2: Examples of viral causes of myocarditis include severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), human immunodeficiency virus, group B coxsackieviruses and dengue virus.
(9)          having a non-viral infection of the myocardium at the time of the clinical onset of heart block;
            Note 1: A non-viral infection of the myocardium can be caused by bacteria, protozoa, fungi or parasites.
            Note 2: Examples of non-viral infections of the myocardium include:
               (a)        Borrelia burgdorferi (Lyme disease);
               (b)        Corynebacterium diphtheriae (diphtheria);
               (c)        Cysticercus species (cysticercosis);
               (d)        Echinococcus species (hydatid disease);
               (e)        Treponema pallidum (tertiary syphilis);
               (f)         Trypanosoma cruzi (Chagas disease); and
               (g)        Toxoplasma gondii (toxoplasmosis).
(10)      having infective endocarditis at the time of the clinical onset of heart block;
(11)      having a mineral or electrolyte abnormality from the specified list of mineral or electrolyte abnormalities at the time of the clinical onset of heart block;
            Note: specified list
