Key result
Severe insulin-induced hypoglycaemia precipitated recurrent atrial fibrillation and prolonged QTc interval, which resolved upon achieving normoglycaemia.
Case Report (n=1)
Severe hypoglycaemia can precipitate transient atrial fibrillation and prolonged QTc interval, highlighting its significant effects on cardiac repolarisation.
Severe hypoglycaemia may trigger transient AF and QTc prolongation; case report leaves open need for prospective arrhythmia monitoring studies.
Hypoglycaemia is associated with various changes in electrocardiography (ECG). We report recurrent atrial fibrillation (AF) and prolonged QTc interval (QT interval corrected for heart rate) precipitated by insulin‐induced hypoglycaemia in a 59‐year‐old patient with type 1 diabetes. The patient was admitted twice (eight years apart) with severe hypoglycaemia. ECG showed AF and prolonged QTc interval on both occasions. Each time, normal QTc interval and sinus rhythm were established when normoglycaemia was achieved. Simultaneous AF and prolonged QTc interval during a clinical episode of hypoglycaemia could explain the true clinical significance of the effects of hypoglycaemia upon cardiac repolarisation.

Hasan et al. (2010) conducted a case report in Type 1 diabetes with severe hypoglycaemia (n=1). Severe hypoglycaemia vs. Normoglycaemia was evaluated on Atrial fibrillation and prolonged QTc interval. Severe insulin-induced hypoglycaemia precipitated recurrent atrial fibrillation and prolonged QTc interval, which resolved upon achieving normoglycaemia.
