Electric chock depends mostly on the current circulating through the body(max 50 miliamp) which depends on the power and voltage of the source.
It seems that, all other conditions equal high frequency is "less dangerous than 60Hz"´
I read somewhere that this is because 6OHz is nearer to our heartbeat fequency

The human body reacts to electricity like it's a capacitor in parallel with a resistance.
As such the lower frequency will 'see' more impedence than the higher frequency, and therefore not tend to be as diminished.
The result is an lesser overall impedence of the flow with the higher frequency and, obviously, the sensation of electrical shock is greater.
This is the very reason why DC is much more dangerous than AC of similar voltage & currents.

Electric shock to a person depends upon the voltage and current passing thru the body and the duration also. The fatality will depend upon the current passed thru the particular body part. A current passing thru heart from a 24V source can be more dangerous than current passing thru other part of body from a 1000V source. Voltage will decide the current passing thru the body. Hence the frequency may not be that important factor in electric shock.

60Hz and 20 kHz are both frequencies of alternating current. It doesn't matter how fast it it turning over but how many Amps are being passed into the body. 1 Amp is more than enough to kill some one if it is passed over the heart.

Hertz is the frequency of alternating current.... the "size" of the electric shock depends more on the voltage potential and the current flow (Volts and Amps).

20 khz. from experience with high power converters.

the apparent "shock" is NOT a product of frequency. only pressure(voltage) or flow(amperage).
