This document contains information about electrocardiogram (ECG) patterns and interpretations, including what normal and abnormal findings represent, thresholds for defining abnormalities, and how different ECG findings correlate to specific coronary artery lesions and regions of the heart. It also provides guidelines for the management of unstable angina/non-ST-elevation myocardial infarction (UNSTEMI) and ST-elevation myocardial infarction (STEMI), including recommendations for medications, fibrinolytic therapy, and percutaneous coronary intervention (PCI).

- 14. UNSTEMI’s Management Relieve angina using Nitrates. Patients using BB must continues using it if not Killip class >III Use BB in pateints with EF preserved. Calcium channel blockers are indicated in patients with nitrates and BB to relief symptoms. Use double antiplatelet theraphy: • If primary PCI: Aspirin 150mg + Clopidogrel 600mg + un-fractioned Heparin 70U/Kg EV + Atorvastatin 80mg. • To fibrinolysis: Aspirin 150mg + Clopidogrel 300mg + un-fractioned Heparin 60U/kg EV + Atorvastatin 80mg. Preferment AtPlase: 0,75mg/kg in 30min then 0,5mg in 1hr EV. If not: streptokinase: 1500.000U EV in 1hr.

- 17. STEMI’s Management Star the chronometer. Calm pain: consider Opioids. Reduce anxiety: consider Tranquilizer in very anxious patients. Use oxygen in patients with SaO2<95%, breathlessness or with acute heart failure. Use double antiplatelet theraphy: • If primary PCI: Aspirin 150mg + Clopidogrel 600mg + un-fractioned Heparin 70U/Kg EV + Atorvastatin 80mg. • To fibrinolysis: Aspirin 150mg + Clopidogrel 300mg + un-fractioned Heparin 60U/kg EV + Atorvastatin 80mg.
