Catecholaminergic polymorphic ventricular tachycardia
Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an inherited genetic disorder that predisposes those affected to potentially life-threatening abnormal heart rhythms or arrhythmias. The arrhythmias seen in CPVT typically occur during exercise or at times of emotional stress, and classically take the form of bidirectional ...
Catecholaminergic Polymorphic Ventricular Tachycardia - Cleveland Clinic
Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a rare heart rhythm disorder. It causes a too-fast heartbeat in your heart ventricles. Usually, you start noticing symptoms of CPVT in childhood.
Catecholaminergic Polymorphic Ventricular Tachycardia
2004年10月14日 · Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an inherited arrhythmogenic disease characterized by cardiac electrical instability exacerbated by acute activation of the adrenergic nervous system.
Catecholaminergic Polymorphic Ventricular Tachycardia
2012年9月27日 · Three new mutations in the triadin gene (TRDN), a protein that links RyR2 and CASQ2, were found in a cohort of 97 patients with catecholaminergic polymorphic ventricular tachycardia, which cosegregated with the disease on a recessive mode of transmission in 2 …
Catecholaminergic polymorphic ventricular tachycardia
A rare, severe genetic arrhythmogenic disorder of the structurally normal heart characterized by catecholamine-induced ventricular tachycardia (VT) manifesting as syncope and sudden death in young individuals.
Catecholaminergic Polymorphic Ventricular Tachycardia - PMC
Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a rare inherited arrhythmia syndrome or channelopathy characterised by exercise- or emotional stress-induced bidirectional or polymorphic ventricular tachycardia in the setting of …
Catecholaminergic polymorphic ventricular tachycardia
Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a condition characterized by an abnormal heart rhythm (arrhythmia). As the heart rate increases in response to physical activity or emotional stress, it can trigger an abnormally fast heartbeat called ventricular tachycardia.
What Is Catecholaminergic Polymorphic Ventricular Tachycardia? - WebMD
2024年9月4日 · Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a heart rhythm problem, or arrhythmia. If you have it, your heartbeat is faster and irregular at times. When this...
Catecholaminergic Polymorphic Ventricular Tachycardia
Catecholaminergic polymorphic ventricular tachycardia (CPVT) results from mutations affecting proteins related to intracellular calcium regulation (particularly diastolic calcium release by the sarcoplasmic reticulum ryanodine receptor) in the heart.
Catecholaminergic Polymorphic Ventricular Tachycardia
Catecholaminergic polymorphic ventricular tachycardia, or CPVT, is a rare genetic condition. It causes an irregular heart rhythm that can be life-threatening. It often shows up in childhood. The first sign is often fainting or near fainting during exercise …
