Current = Voltage/Resistance (Ohm's Law) Therefore, for a fixed resistance, current is proportional to voltage. Also, I believe the safe current level in humans is in the 10's of milliamps.
High voltage causes break down of materials and interference with electrical (or neural) systems. High current flow creates heat. Once an insulator is compromised (by high voltage breakdown) it may allow a continued flow of current, causing thermal damage.
However, in the case of ESD, there isn't a continuous source of charge. Once the initial charge is dissipated, current flow stops. This is why your PDA may lock up from ESD but can be reset and keep working.
