good cardiac doctors in bangalore Common Cardiac Emergencies Acute Coronary Syndrome (ACS) Includes unstable angina, NSTEMI, and STEMI. Management: Administer aspirin, nitroglycerin, morphine (if needed), and anticoagulants. Perform an ECG within 10 minutes of presentation. If STEMI is confirmed, consider reperfusion therapy (PCI or thrombolytics). Cardiac Arrest Immediate initiation of CPR and advanced cardiac life support (ACLS) protocols. Determine the rhythm (shockable vs. non-shockable) and manage accordingly (defibrillation for VF/VT or epinephrine for asystole/PEA). Arrhythmias Bradycardia: Treat with atropine, pacing if unstable. Tachycardia: Use synchronized cardioversion for unstable tachycardia or pharmacologic treatment for stable cases (adenosine, amiodarone, or beta-blockers).
