Portable monitoring, which includes two main types:.

Radiographic imaging, such as chest X-ray, CT scan or MRI.

Heart function tests: Several tests can help doctors check the function of your heart.

Laboratory testing: Blood work and other lab tests can detect abnormal electrolyte or thyroid hormone levels, which can be signs of arrhythmia.

We’ll likely order an electrocardiogram (EKG), to see if you have a prolonged QT interval or other issues with the electrical activity of your heart. They may refer you to a cardiologist or an electrophysiologist, a doctor who specializes in diagnosing and treating arrythmia (irregular heartbeat). To diagnose long QT syndrome, your doctor will start with a thorough physical exam and ask about your family history and any symptoms you may be experiencing.

With inherited long QT syndrome, you may not have any symptoms. These conditions lower the sodium or potassium levels in your blood, which can trigger long QT symptoms. Certain health conditions can also cause it, such as severe diarrhea, vomiting, eating disorders like anorexia nervosa and bulimia, and some thyroid disorders. Some medications like antibiotics, diuretics and antihistamines can cause acquired long QT syndrome. Occasionally, long QT syndrome is acquired and develops during your lifetime. Most often, long QT syndrome is inherited, meaning it’s passed down from your parents’ genes. The most dangerous side effect of long QT syndrome is sudden cardiac arrest, which happens when your heart suddenly stops beating.

Long QT syndrome causes fast, erratic and sometimes dangerous heartbeats, usually when you exercise or feel stressed. Doctors can often see this delay as a pattern, called prolonged QT interval, on an electrocardiogram (EKG). With long QT syndrome, it takes longer to recharge between beats. Normally after each heartbeat, it recharges itself to prepare for the next one. Your heart's electrical system controls the coordinated action of contracting and relaxing the heart muscle to pump blood. Long QT syndrome (LQTS) is an abnormality in the rhythm of your heartbeat.
