What you have to understand is that when we talk about adrenalin and potassium, we're talking about what we refer to as a mechanism of death, not the actual cause of death. Just for your information, the cause of death is defined as the disease or injury that initiates a downhill sequence of events ending in death. That's very different from looking at the potassium or the adrenalin levels.
