What Causes Rapid Heart Rate?

I experienced today while running at approximately 10mph a sudden jump in my heart rate. It happened at approximately 3/4 of a mile. It went from a steady 155bpm at this pace to over 200bpm. It peaked out at 228bpm when I got light headed and had to slow down. I had to drop to a walk to get my heart rate to begin to come back down. It felt very uncomfortable and the rhythm felt wrong and erratic. After my heart rate reached the low 190bpm range it suddenly dropped back down to 160 and it felt like it had resumed a normal rhythm and then very quickly leveled off to 115bpm before I resumed running at a slow pace. I have a tested max heart rate of 192bpm and a resting heart rate of 44bpm. I'm 25 years old. I was wearing a heart rate monitor when this happened. Should I be concerned that this could kill me?
