The treatment for short QT syndrome is aimed at preventing abnormal heart rhythms and reducing the risk of sudden cardiac death. It has been difficult to experimentally test potential treatments as the condition is very rare, so the evidence for treatment effectiveness comes largely from consensus opinion. [ 1 ]
Sudden arrhythmic death syndrome (SADS) is a sudden unexpected death of adolescents and adults caused by a cardiac arrest. However, the exact cause of the cardiac arrest, and thus the exact cause of death, is unknown. These deaths occur mainly during sleep or at rest. [7] One type of conduction defect known as Brugada syndrome can be ...
Romano–Ward syndrome is a descriptive term for a group of subtypes of long QT syndrome, specifically subtypes LQT1-6 and LQT9-16. [8] Several subtypes of Romano–Ward syndrome have been described based on the underlying genetic variant. [5] These subtypes differ in clinical presentation and their response to treatment.
Those affected by arrhythmogenic cardiomyopathy may not have any symptoms at all despite having significant abnormalities in the structure of their hearts. [6] If symptoms do occur, the initial presentation is often due to abnormal heart rhythms (arrhythmias) which in arrhythmogenic cardiomyopathy may take the form of palpitations, or blackouts. [7]
Jervell and Lange-Nielsen syndrome causes severe sensorineural hearing loss from birth, affecting both ears. Those affected have a prolonged QT interval on an electrocardiogram and are at risk of abnormal heart rhythms (arrhythmias), which can cause dizziness, blackouts, or seizures. [2]
Torsades de pointes is associated with long QT syndrome, a condition whereby prolonged QT intervals are visible on an ECG. Long QT intervals predispose the patient to an R-on-T phenomenon , wherein the R-wave, representing ventricular depolarization, occurs during the relative refractory period at the end of repolarization (represented by the ...
The resting 12-lead ECG is a useful test to differentiate CPVT from other electrical diseases of the heart that can cause similar abnormal heart rhythms. Unlike conditions such as long QT syndrome and Brugada syndrome, the resting 12-lead ECG in those with CPVT is generally normal. [8]
Treatment antiarrythmic agents , diuretics , catheter ablation , pacemaker [ 1 ] Tachycardia-induced cardiomyopathy (TIC) is a disease where prolonged tachycardia (a fast heart rate) or arrhythmia (an irregular heart rhythm) causes an impairment of the myocardium (heart muscle), which can result in heart failure .
