What I don't understand is, if the sound of a popping balloon would be enough to kill him, it doesn't make sense that the family didn't know about his condition. If his heart was really that bad that just one sound would bring him down, it seems like he would be so weak already that they would notice something was wrong, just in everyday living. It would mean that normally he would not be able to run and play, or be surprised from behind by friends, or anything moderately stressful. The heart normally is the strongest muscle in the body, so a very weak heart that couldn't beat fast for even a minute's time would be noticeable. So this is making me think twice about the whole story.
The child had a relatively rare heart condition called hypertrophic cardiomyopathy. In simplest terms, what it means is that the heart muscle itself was much "thicker" than you would see in a normal heart. With more muscle, the more blood flow is required to keep the muscle alive and well. With a traditional heart attack that one thinks of in older individuals, it is usually because the coronary arteries, the arteries that supply blood to the heart, become clogged and hinder blood flow. In this child's case, the blood flow was there, but it was not adequate enough to supply the "extra" heart muscle that was there. So when the heart beated faster, which required more oxygen via the blood, it didn't receive it which probably lead to ventricular fibrillation and sudden death in this child.
What is most devastating about hypertrophic cardiomyopathy, especially in children, is that its first presentation can be sudden death with no preceding symptoms as apparently was the case with this child. It is just a matter of what precipitating event will push it over the edge. As suprising as it may be, most young patients with this heart condition are usually asymptomatic until the precipitating event. The coronor's analogy to a popping balloon was likely an indication that the child's heart was likely so badly "damaged" that it was literally, and unfortunately, a ticking time bomb. The emotional stress that a child of that age would likely experience being strapped into an enclosed space with flashing buttons and loud noises may have been the most emotional/physical stress he had experienced up to that time in his life and it pushed him over the edge. The "experience" of MS is likely what indirectly caused this child's death, not the forces or safety of the ride. That is where the family will have a difficult time in the courtroom, imo. If it wasn't that, his heart would have continued to get progressively worse as he aged and he likely would not have made it into his adolescent years with the degree of hypertrophy he reportedly had. The most commonly heard story with a child with this type of heart condition is playing a sport in middle or high school and suddenly dropping dead on the field. Its scary, but again rare.
A careful cardiac exam by his pediatrician may or may not have picked up an irregular heart beat, extra heart sounds or a history of filling dizzy or passing out. Being only 4, there was likely a genetic cause in this case, so it would be interesting to know if there is a family history of heart conditions, sudden death, or arrythmias of unknown origin.
