Summary
A 58-year-old man experienced ventricular fibrillation due to low potassium. Investigations revealed an adrenal adenoma, a secondary cause of hypertension, highlighting the need for thorough diagnosis to prevent severe complications.
Area of Science:
- Cardiology
- Endocrinology
- Nephrology
Background:
- Ventricular fibrillation is a life-threatening arrhythmia.
- Hypokalemia can precipitate cardiac arrhythmias.
- Secondary hypertension requires identification of the underlying cause.
Observation:
- A 58-year-old male presented with ventricular fibrillation and subsequent hypokalemia (1.8 mEq/L).
- Electrocardiography and echocardiography indicated left ventricular hypertrophy.
- Imaging revealed a right adrenal mass.
Findings:
- Coronary angiography showed no structural heart defects.
- Laboratory tests revealed suppressed renin and elevated aldosterone levels, suggestive of primary aldosteronism.
- Surgical resection of the adrenal adenoma was performed.
Implications:
- This case underscores the importance of investigating secondary causes of hypertension.
- Early diagnosis and management of adrenal adenomas can prevent severe cardiovascular events.
- A systematic diagnostic approach is crucial in managing complex hypertensive cases.
