Catecholaminergic Polymorphic Ventricular Tachychardia
Catecholaminergic Polymorphic Ventricular Tachychardia (CPVT) is a genetic heart disease in which the electrical activity of the heart is disturbed: this may cause dangerous cardiac arrhythmias.
The heart is more sensitive to stress hormones produced by the body during certain conditions, especially when combined with stress, exercise, emotions and sport.
of people with CPVT, a hereditary cause is found (DNA Testing)
Possible signs and symptoms of CPVT are:
Shortness of breath, problems by exercise and reduced endurance
Cardiac arrhythmia: severe arrhythmia can sometimes cause dizziness, fainting and even sudden cardiac death
In the course of life
The symptoms occur mainly during physical exercise and emotional stress, and usually in childhood. CPVT is a rare heart disease. The symptoms vary from gene carrier to gene carrier: some may experience severe heart problems while others have no symptoms at all. In case of symptoms, it is important to discuss this it with your GP so that a cardiovascular examination can be carried out.
ACCORDING TO SIGNS AND SYMPTOMS
Depending on the symptoms and the LQTS type, beta-blockers can be prescribed.
ICD / Pacemaker
If there is a risk of dangerous cardiac arrhythmia, an ICD can be implemented.
CPVT gene carriers have to handle strong emotions and stress with care.
CPVT patients should strongly avoid intensive exercise and sport.
An ultrasound of the heart provides a clear image and sound of the function and shape of the heart muscle and valves.
The MRI examination, which generates radio wave (magnetic) signals, provides a clear picture of the heart (chambers).
In an electrocardiogram, the electrical signals of the heartbeats are properly recorded and can be analyzed.
• Cardiovascular examination may also include a Holter monitor test and/or an exercise test/cycle test.
Discuss it with your GP or cardiologist
If you’re experiencing some signs and symptoms, or if other family members have been found with a predisposition for the genetic heart disease CPVT, please discuss it with your GP/cardiologist so that additional cardiovascular examination can be assessed.
