Clinical manifestations
This abnormal heart rhythm is one of the two deadly heart rhythms (fatal cardiac arrhythmias) and is often suffered by those with this jeaopardy's syndrome.
What is ventricular fibrillation (V-fib)?
This condition may also impact the nervous system, causing this sudden surge of abnormal electrical activity in the brain
What is seizure?
This type of test involves wearing a portable ECG for a full day and night.
What is Holter Monitor Test?
An antiarrhythmic medication administered to treat some types of irregular heartbeats. Can also be used to treat malaria.
What is quinidine?
The condition may explain this leading cause of death in infants aged 1 month to 1 year.
What is sudden infant death syndrome (SIDS)?
A neurological symptom/event that may be caused by cardiac arrest, often leading to misdiagnosis as epilepsy.
What is a seizure?
Part of the heart that’s located in the upper right ventricle where most of the electrical abnormalities occur.
What is right ventricle?
One of the fastest tests one can run on the heart. An electric current tracking machine which can show signs of unusual signals in the heart. Results may reveal T wave inversions and/or saddleback-shaped ST elevations.
What is 12-lead electrocardiogram?
Procedure where you heat-kill a portion of tissue of the heart to prevent it from causing abnormal rhythms.
What is cardiac/catheter/radiofrequency ablation?
Indication of quinidine which includes a barrage of frequent life-threatening arrhythmias caused by the abnormal electric signals in the heart.
What is electrical storm?
Time of day associated with increased vagal tone, and when life-threatening events are most likely to occur in this condition.
What is night time, during sleep?
The process in which the heart muscle cell’s membrane potential returns to normal. An issue in this process is thought to be caused by this jeopardy's condition.
What is repolarization?
This test can be used to diagnose structural issues within the heart and involves using a contrast dye.
What is echocardiogram?
Behavioral changes to help prevent cardiac issues and possibly treat symptoms of this syndrome.
What is exercise and improved diet?
This disease is more common in men, and researchers suspect is may be because of this hormone.
What is testosterone?
This symptom – a brief loss of consciousness caused by a drop in blood flow to the brain – may precede a cardiac arrest.
What is syncope?
A genetic mutation disrupts the flow of this ion into the heart, disrupting electrical signals.
What is sodium?
A type of drug test that involves administering a sodium channel blocker like ajmaline to reveal diagnostic ECG patterns.
What is drug challenge test?
Drug that normalizes ECG pattern by increasing ICa-L
What is isoproterenol.
A portable emergency shocking device which may restore normal heart rhythm of a patient suffering from this syndrome.
What is automated external defibrillator (AED)?
When sleeping, patient exhibits a breathing pattern that is staggered and clearly labored. Sounds like gasping or aggressive snoring like an involuntary gasp reflex. Occurs ~every 6 seconds. May accompany cyanosis.
What is agonal respiration?
Elevated body temperature which can worsen certain cardiac conditions by disrupting ion channels.
What is fever?
A doctor may use this tool to hear irregular heart rhythms.
What is stethoscope?
Implanted device which is proven treatment to prevent sudden death from ventricular arrhythmias.
What is implantable cardioverter-defibrillator (ICD)?
Term to describe a condition or syndrome that has evidence of running in families.
What is heritable/hereditary/genetic?
