Hypoglycemia at Night Tied to Arrhythmias

Nocturnal hypoglycemia was a major risk factor for cardiac arrhythmias in type 2 diabetes patients who were already at an increased risk for cardiovascular events, according to British researchers.

Most hypoglycemic episodes among the 25 patients occurred at night and were asymptomatic. But bradycardia was eight-fold higher during nocturnal hypoglycemia episodes compared with normal glucose periods (incident rate ratio 8.42, 95% CI 1.40-51.0, P=0.02) and atrial ectopic activity was nearly four...
