Cardiac Arrest with Successful Resuscitation and Post-Resuscitation Management
Keywords:
Sudden cardiac death, medically induced hypothyroidism and hypoparathyroidism, ventricular tachycardiaAbstract
Introduction: Sudden cardiac arrest (SCA) remains a critical global health challenge, frequently precipitated by life-threatening arrhythmias. Despite advancements in cardiopulmonary resuscitation (CPR) techniques, the prognosis and neurological outcomes remain poor, particularly in cases of prolonged asystole. Case Description: This article presents a clinical case of a 68-year-old female with a medical history of total thyroidectomy and concomitant hypoparathyroidism. The patient experienced a sudden cardiac arrest requiring 35 minutes of resuscitation. Clinical evaluation revealed severe hypothyroidism ($TSH$ - 43.04 mIU/ml), hypocalcemia, and a persistently prolonged $QTc$ interval.Shutterstock Explore Results: Following the exclusion of vascular pathology, a single-chamber implantable cardioverter-defibrillator (VVI-ICD) was implanted to manage arrhythmogenic risks. In the postoperative period, the device successfully terminated three episodes of ventricular tachycardia. The patient was discharged in stable condition with significantly improved neurological status. Conclusion: Endocrine disorders, specifically severe hypothyroidism and hypocalcemia, are significant risk factors for fatal arrhythmias. ICD implantation in such cases ensures a high probability of survival and effective long-term management.
