Blackouts signal heightened risk of sudden death

Blackouts and near drowning events might signal an increased risk of sudden death, reveals new study.

The annual congress of the South African Heart Association will be held in Rustenburg from October 25-28, 2015. Experts from the European Society of Cardiology (ESC) will present a special programme.

LQTS is a cardiac disorder related with blackouts (syncope). It is a treatable cause of sudden death but unfortunately blackouts, being common and often not serious, are often overlooked and the small group with serious events is then missed, Professor Brink said.

Many patients with LQTS never visit a doctor, or when they do, they are given a wrong diagnosis, noting that the most common misdiagnosis in living patients was epilepsy, while in those who died it was drowning, according to the study.

Fainting at the sight of blood is harmless, but a blackout during activity is cause for further investigation, Brink said.
