According to Nicholi Tesla, I heard that if high voltage AC frequency is high enough, it will not electrocute you (even if the voltage is high). How high does this frequency have to be minimum in order for it to not electrocute you (considering your grounded and touch the live wire for a brief moment.)?

If you look at the apparatus Tesla used you will see very high voltages at very high frequencies and very, very low currents. Current being the key to his demonstrations, acting more like static charges at these values.

There is a "skin effect" when a conductor carries ac electricity. It can confine currents to about a centimeter at 1 khz if the path is along the body. If the ingress and exit for the current are diametrically across from each other, the skin effect will not overwhelm the lower resistance of the straight path. Also, the current density only drops off as 1/e, so significant current goes deeper. Tasers do depend on the effect for heavy influence on musculature control with minimal heart effect. The U.S. military is testing microwave and terahertz frequency electromagnetic sources as Active Denial area protection. Standing in the beam makes you feel as though your skin is on fire, but it's almost impossible to cook you deep enough to do significant damage.

I thik the higher frequencies tend to not go directly through the body as easily as the lower frequency ones. However if it does go through your body passing through your heart you are just as dead.
Note that the high voltage for TV CRT monitors is about 15750 Hz. Those all have a warning saying danger of death if you touch the flyback transformer at that frequency with high voltage.

Since it is the amount of current passing through the body that is lethal, there are other variables that you need to consider such as the resistance of the victim (are they drenched in salt water?) and the voltage of the AC source. Then you could determine the lethal frequency.

I think electricuted is once the amount of voltage will overcome your breakdown voltage resistance. Knowing that all matters having breakdown voltage resistance if this one will overcome by the voltage supplying to it then there will be high current surge passing thru that matter.
