The patient had no other cognitive and motor impairment except for memory impairment. We report a case of 27-year-old man who experienced TGA after radiofrequency catheter ablation of supraventricular tachycardia. Transient total amnesia after radiofrequency ablation is rare and its etiology is unknown.
TGA with short duration and benign prognosis is usually neglected in clinical practice. Transient global amnesia (TGA) is a neurological disorder characterized by sudden onset of anterograde amnesia with or without retrograde amnesia, lasting less than 24 hours, without other clinical neurological dysfunction. Keywords: Transient global amnesia (TGA) paroxysmal supraventricular tachycardia radiofrequency catheter ablation There are still many unsolved mysteries worthy of long-term follow-up. The outcome of patient with TGA is benign. The patient received low flow oxygen inhalation and aspirin 300mg orally. There was no cerebral infarction and cerebral hemorrhage. Head magnetic resonance examination magnetic resonance imaging (MRI) showed dots in right frontal lobe and bilateral ventricles in T2-weighted images. There is no abnormality in electrocardiogram (ECG), chest X-ray, cervical vascular ultrasound, and cardiac color Doppler ultrasound examination. Tests were performed immediately and normally including blood routine examination, liver and kidney function, electrolyte, blood glucose, thyroid function, blood coagulation function, D-dimer, myocardial injury markers, blood gas analysis and other hematological. Nervous system examination showed that 12 pairs of cranial nerves were normal, the muscle strength and muscle tone of the limbs were normal, physiological reflexes existed, and no pathological reflexes were elicited. The symptom lasted for about six hours and relieved without recurrence. Abstract: Transient global amnesia (TGA) is a neurological disorder characterized by sudden onset of anterograde amnesia with or without retrograde amnesia, lasting less than 24 hours, without other clinical neurological dysfunction.
