(NEW YORK) — An electrical heart abnormality may be more dangerous that doctors previously believed.
According to a study published in the Journal of the American Medical Association, a cardiac condition known as left anterior fascicular block may be a sign that a patient is at risk of developing severe heart problems.
In the study, 39 individuals with LAFB were compared to over 1,600 healthy individuals to determine the health impacts of the condition.
The study concluded that those with LAFB were at increased risk of other heart rhythm problems, heart failure and death.
The study only looked at patients over the age of 65, using a simple electrocardiogram.
According to HealthDay News, there is no treatment for LAFB.
