What is the Long QT Syndrome?

A long QT Syndrome is a condition related to the heart rhythm that has a potential of causing fast and chaotic heartbeats. Fainting spell or seizures are the common occurrence in patients who have rapid heartbeat due to Long QT Syndrome.

Patients suffering from this condition need to avoid specific medications which trigger the syndrome further. Living and thriving with the condition is also possible after a proper treatment. Consulting a doctor becomes important when patients suddenly start fainting after physical activities or even with emotional excitement. If taking a new medication, especially the ones which prolong the QT interval is also a sign for you to get yourself checked.

In order to diagnose this syndrome, your symptoms will be reviewed by the doctor, following which a number of tests will be performed to determine the problem. Tests like electrocardiogram, holter monitor and event monitor are used to check the heart rhythm and the activities.

How is the Long QT Syndrome treatment done?

Simple preventive measures are the basic treatment method for this syndrome. Medications and left cardiac sympathetic denervation surgeries can also be needed in some cases.
