Medical Conditions - Sudden Cardiac Death

Sudden cardiac death (SCD) is a sudden and unexpected death caused by a loss of heart function. It can occur in people with or without known heart disease. SCD is responsible for a significant number of deaths worldwide, constituting approximately 15% of all mortality cases. It is often caused by ventricular arrhythmias, which are abnormal heart rhythms that can disrupt the heart's pumping function. Other risk factors for SCD include a family history of heart disease, smoking, high blood pressure, and obesity. Symptoms of SCD can include fainting, dizziness, chest pain, and shortness of breath.
