The lesson plan introduces students to case study support and myocardial infarction diagnosis over 50 minutes. It aims to: 1) introduce case studies and external research; 2) teach how to approach and solve case studies; 3) combine research and knowledge to solve problems; 4) provide knowledge on myocardial infarction diagnosis and treatment; and 5) discuss maintaining cardiovascular health. Students will apply information to a case study, make a clear diagnosis, and gain understanding of myocardial infarctions, their diagnosis, treatments and causes. The teacher will present a patient case study and lead discussion of symptoms, ECG readings, and the final myocardial infarction diagnosis and its treatment/mitigation.
