I'm joining the army but fear i will get sudden cardiac arrest triggered by intensiv exercise ?! should i go cardiologist for tests, to reassure ?

Bayes theorem: Hi. Bayes theorem states that, post test probability of an event prediction or disease, is influenced by not only sensitivity and specificity of the test but also pretest probability of event or disease. Your pretest probability of sudden cardiac arrest at your age in the absence of a horrible gene or dysrhythmia (VERY rare things), is essentially zero. Since no test is perfect, I advise no test.
