Long QT Syndrome – Symptoms, Causes & Treatments

Long QT syndrome LQTS is a medical condition that affects the usual electrical activities of your heart. It takes longer for your heart muscles to recharge in between beats, which causes many serious health issues. This is not a common problem, affecting around 1 out of 2000 people. However, it can be hard to identify the condition as the symptoms might be not obvious. The key is to manage your condition and prevent it from happening. Let’s take a look at our guide to learn more about the symptoms, causes, and treatments for long QT syndrome.

5 Symptoms of Long QT Syndrome


Fainting is the most common symptom of long QT syndrome. This condition is caused when your heart temporarily beats in an erratic pattern. Syncope or fainting spells would occur when you are scared, angry, excited, or doing some exercises. In some cases, you might even lose consciousness without a warning from being startled by ringing sounds from the phone. This is quite different from a usual fainting spell, which often comes with a first warning sign, such as blurred vision, weakness, irregular heartbeat, heart palpitations, or lightheadedness. Make sure to visit a doctor immediately after a fainting spell to get proper medical treatment. [1]
