Living with Familial ventricular tachycardia

A fast heart rhythm starting in the lower heart chambers that is caused by an inherited gene change.

Understanding Familial ventricular tachycardia

Familial ventricular tachycardia is ventricular tachycardia, a fast heart rhythm from the lower heart chambers, caused by an inherited change in the genome.

GARD describes it as passed down in an autosomal dominant way. It may come in episodes (paroxysmal). A complete right bundle branch block, a change in the heart's electrical pathway, can also occur.

Signs & symptoms

GARD lists these findings, and we don't have enough information about how common they are:

  • Episodes of fast heartbeat (paroxysmal ventricular tachycardia)
  • Right bundle branch block (electrical change)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

Care & treatment

Care team
A doctor familiar with rare conditions, plus specialists as needed
Expert care
Ask about multidisciplinary care centers for rare conditions
Treatment
GARD doesn't list specific treatments for this condition. Your care team will tailor care to your symptoms.
Research
Clinical trials and observational studies may be options. See the research section below.

General information, not medical advice. Your care team makes the decisions.

Everyday life

Living with a rare condition is easier with support.

  • Connect with rare disease patient organizations for support
  • Keep notes on symptoms, changes and questions for appointments
  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits
Bring these questions to your next doctor visit
What heart rhythm testing should I have?
Should my relatives have heart checks?
Is genetic testing available for my family?

Quick facts

InheritanceAutosomal Dominant

An inherited change in the genome causes it. It is autosomal dominant, which means one changed copy of a gene is enough. GARD doesn't name a gene.

Also known as: hereditary ventricular tachycardia; ventricular tachycardia, familial; ventricular tachycardia, familial polymorphic; ventricular tachycardia, idiopathic
