What Your Gut Says: The patient has a tachydysrhythmia which may be the presentation of acute coronary syndrome (ACS) even though the patient has no ischemic symptoms. Up to 80% of patients will have at least one troponin sent ( Gabrielli 2022 ). Type 2: MI secondary to ischaemia, but not related to coronary atherosclerosis.
