Glossary for Ventricular arrhythmia

  • Andersen-Tawil syndrome: A rare disorder where a genetic mutation causes periods of muscle weakness, heart rhythm abnormalities and various physical development abnormalities. It is believed to be caused by problems with the way the body utilizes potassium.
  • Arrhythmias: Irregularity in the heart's beating rhythm.
  • Atrial flutter: Heart arrhythmia where atria beat more often than ventricles
  • Brugada Syndrome: A rare genetic disorder characterized by heart rhythm abnormalities which can result in sudden death if untreated. The condition may be inherited in some cases. The mean age of sudden death is 40 years of age.
  • Brugada syndrome 1: A rare genetic disorder characterized by heart rhythm abnormalities which can result in sudden death if untreated. Type 1 is caused by a mutation in the SCN5A gene on chromosome 3p21. Symptoms most often occur during the night and the condition is most prevalent in Japan and Southeast Asia.
  • Brugada syndrome 2: A rare genetic disorder characterized by heart rhythm abnormalities which can result in sudden death if untreated. Type 2 is caused by a mutation in the GPD1L gene on chromosome 3p22.3. Symptoms most often occur during the night and the condition is most prevalent in Japan and Southeast Asia.
  • Brugada syndrome 3: A rare genetic disorder characterized by heart rhythm abnormalities which can result in sudden death if untreated. Type 3 is caused by a mutation in the CACNA1C gene on chromosome 12p13.3. Symptoms most often occur during the night and the condition is most prevalent in Japan and Southeast Asia.
  • Brugada syndrome 4: A rare genetic disorder characterized by heart rhythm abnormalities which can result in sudden death if untreated. Type 14 is caused by a mutation in the CACNB2 gene on chromosome 10p12. Symptoms most often occur during the night and the condition is most prevalent in Japan and Southeast Asia.
  • Chest conditions: Any condition affecting the chest
  • Chest discomfort: The sensation of discomfort that is located in the chest
  • Chest pain: Pain in the chest area.
  • Circulatory system conditions: Medical conditions affecting the heart and the circulatory system.
  • Dizziness: Feelings of lightheadedness or giddiness.
  • Fainting: Temporary loss of conciousness or fainting.
  • Heart conditions: Any condition that affects the heart
  • Palpitations: The subjective sensation of the beating of the heart at a rapid or irregular rate
  • Periodic paralysis, potassium-sensitive, cardiodysrythmic type: A rare disorder where a genetic mutation causes periods of muscle weakness, heart rhythm abnormalities and various physical development abnormalities. It is believed to be caused by problems with the way the body utilizes potassium. Periodic paralysis may start as early as infancy or during the second decade and is triggered by exercise, stress or prolonged periods of rest.
  • Rapid heart beat: Excessively rapid heart beat.
  • Scleroderma: A rare, progressive connective tissue disorder involving thickening and hardening of the skin and connective tissue. There are a number of forms of scleroderma with some forms being systemic (involving internal organs).
  • Sick sinus syndrome: Heart rhythm disorder
  • Sinus bradycardia: A condition which is characterized by a slow heart rate
  • Sinus tachycardia: A condition which is characterized by a fast heart rate
  • Supraventricular Tachycardia: A rapid heart rate, the cause of which originates above the ventricles.
  • Syncope: Temporary loss of conciousness or fainting.
  • Ventricular tachycardia: A condition which is characterized by a fast heart beat originates from the ventricles
  • Wolf-Parkinson-White syndrome: Heart arrhythmia causing increased heart rate
