A genetically transmitted rhythm disturbance that places children at risk for ventricular fibrillation and sudden death.
A rare, inherited, sometimes fatal disorder of the heart’s electrical system. Under great emotional or physical stress, this abnormality may weaken the ability of the heart to maintain a normal rhythm and pump effectively. The result can be reduced blood flow to the brain, which may cause sudden fainting. People with this disorder may also develop a very fast heartbeat, which can accelerate to 350 beats per minute (ventricular fibrillation). This quickly tires the heart and, if untreated, causes it to stop pumping and death results.
Within the realm of cardiac health, there exists a rare hereditary cardiac ailment characterized by a disturbance in the heart’s rhythm, resulting in swift and disordered heartbeats that may lead to a temporary loss of consciousness or, in severe cases, sudden death. Furthermore, it is worth noting that specific medications have the potential to trigger this condition. The term “long QT” pertains to the distinctive pattern of this abnormal heart rhythm as observed on an electrocardiogram, a diagnostic tool used to assess the heart’s electrical activity.
