This beautiful little girl is my 7 year old niece, Courtney.  She has bradycardia.  From my research, I've learned that only 1 in 50,000 children are diagnosed with this heart condition.  Maybe, it will help someone else whose child has been misdiagnosed. 

This is where the person stares, unblinking, into "somewhere out there,"  and no amount of calling them, snapping your fingers in front of their eyes, or talking to them brings them out of it.  Courtney's dad has done this from the time he was a small boy. 

Atonic Seizures.

This is when the person loses muscle strength.  If standing, they will suddenly, and without warning, simply fall to the ground.  

Tonic Seizures.

If a person has atonic seizures, they may also have tonic seizures.  All muscles will suddenly stiffen, and the person cannot relax their body. 

Sinus Bradycardia, which is normal due to deep relaxation, or in a well-trained athlete.

Sick sinus syndrome is a condition in which the heart’s natural pacemaker malfunctions, causing an irregular heartbeat.

Heart block is a condition in which electrical impulses are slowed or blocked as they travel from the atria through the AV node into the ventricles.
There are 3 different types of blockages. Courtney was diagnosed with Type II heart block. Some of the electrical impulses are unable to reach the ventricles, usually because of an underlying disease. (In this case, she had none.) This condition generally carries more risk and is less common. A pacemaker is usually prescribed, and Courtney does have one. Eventually, it does turn into Type III, which is the deadliest. Courtney's dad was diagnosed with having Type III third-degree heart block. He wears a pacemaker as well.

A bundle branch block is a when the electrical impulses traveling through the heart are slowed or blocked completely from traveling along their normal route through the ventricles.

There are also 3 different types of these blocks.
