Thank-you. I have personal knowledge of similar tragic situations long before the Covid Jab. The key element is a sudden blow to the chest that sets the heat into arrhythmia. Rare, but deadly.
There are also hereditary conduction disturbances that make someone much more vulnerable to this situation. They are asymptomatic and difficult to detect on routine EKG (like Brugada syndrome, prooonged QT syndrome etc)
