Is the LGL syndrome inheritable?

There are indications that the LGL syndrome is possibly inherited. However, this is not certain and needs to be further researched.

These are the symptoms of an LGL syndrome

The LGL-syndrome is characterized by tachycardia. This seizure-like tachycardia is called paroxysmal tachycardia by physicians. The very fast heartbeat has a frequency between 200 and 250 beats per minute.

There is no identifiable cause for the rapid heartbeat, such as a stress or dangerous situation, which would explain such a reaction. A tachycardia without a recognizable cause is usually perceived by those affected as very unpleasant and frightening. The tachycardia manifests itself as a throbbing feeling in the chest and a high pulse.

Furthermore, it can lead to a syncope, i.e. a short fainting spell. The seizure-like tachycardia then stops of its own accord. How often and how long the tachycardia occurs varies from individual to individual. The tachycardia attacks can be strenuous for those affected, so that many feel very exhausted after an attack.

  • Vertigo,
  • Nausea,
  • Sweat and damp hands,
  • Rapid breathing or shortness of breath,
  • Trembling and inner restlessness come.

Therapy of the LGL syndrome

Studies have not found that patients with LGL syndrome have an increased risk of sudden cardiac death. Also other risks are not associated with the diagnosis of LGL syndrome. So far, however, there is still little data on LGL syndrome.

How the LGL syndrome develops individually is different. In the worst case, the frequency and duration of the seizure-like tachycardia can increase. It is recommendable to have a cardiologist at your side.
