9               Factors that must exist
At least one of the following factors must exist before it can be said that, on the balance of probabilities, heart block or death from heart block is connected 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 amyloidosis or sarcoidosis at the time of the clinical onset of heart block;
(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 of mineral or electrolyte abnormalities is defined in the Schedule 1 - Dictionary.
(12)      taking a drug from the specified list of drugs within
