What else can cause Long QT?
Andersen–Tawil syndrome
Anderson-Tawil syndrome affects the heart by prolonging the QT interval, a measure of how long it takes the heart to relax after each heart beat. This, as in other forms of long QT syndrome, can lead to abnormal heart rhythms such as ventricular ectopy or ventricular tachycardia causing palpitations. The ventricular tachycardia seen in Anderson-Tawil syndrome often takes a form known as bidirectional ventricular tachycardia. The arrhythmias seen in association with the condition can cause sudden cardiac death, but the risk of this is lower than in other forms of Long QT syndrome.
Effects of overtime
Long-term effects were researched by The University of Texas Health Science Center at Houston. They studied the link between overtime and the increased risk of cardiovascular disorder (CVD) events. Their results included evidence that showed that for people who worked at least 10 years for each additional hour worked, starting from the 46th hour, his or her risk of a CVD event increased by 1%. In addition to these health risks, María Beniell, who received her Ph.D. in Economics from the Center for Monetary and Financial Studies (CEMFI), researched the correlation between working long hours and the likelihood of individuals smoking, drinking, having a high body mass index (BMI), and being less physically active. The long-term effects of alcohol consumption include increased on-the-job injuries and loss of productivity, family problems, risk of high blood pressure, stroke, other cardiovascular diseases, and more. The effects of smoking, in addition to similarities of the effects of alcohol, include increased risk of heart attacks, emphysema, and a large amount of cancers.
