You are extremely lucky. It only takes 50 mA of 60 Hz AC to fibrillate the heart. You hit a combination that is often lethal:
* 60 Hz AC (DC is less lethal, higher frequencies are also less lethal)
* High voltage
* A voltage source with near infinite current sourcing ability (as far as your life is concerned)
Most of the electrical resistance in our bodies is in the skin, and is typically around 50 kOhms if dry. The rest of the body is considerably less, and is pretty much significant. Your footgear may have also been working in your favor, especially if they were dry.
If your total resistance of skin and clothing was around 250 kOhms, then you would have had 500 mA flowing through you. Since you literally burned a whole in your foot (ie you became a giant human welding rod), I would guess that current flow was way higher that that. Either way, plenty to interrupt your heart rhythm. Either the circuit was really short lived, or the current flow through your body was primarily in low resistance tissues that diverted it away from the heart
One factor working in your favor is that you didn't grab the line with one hand while the other was touching the lift. That would have put the voltage directly across your heart while also seizing up your muscles so you couldn't let go.
Glad you are still with us
