Myocarditis is an inflammatory condition of the myocardium requiring meticulous nursing management for optimal patient outcomes. Effective management begins with a thorough assessment of the patient's medical history, paying close attention to past infections, autoimmune disorders, travel history, and exposure to toxins or drugs. Recent viral infections and systemic diseases are particularly relevant due to their potential role in triggering myocarditis.Physical Examination and MonitoringThe...
