        Current path through body. The current path is also important because of the organs that may be affected. For example, a hand-hand path, as shown in Fig. 1, causes the current to pass directly through the heart. A left hand-left foot path, as shown in Fig. 2 (on page 38), again causes the current to pass through the heart. A right hand-right foot path, as shown in Fig. 3 (on page 38), or hand to elbow path is not quite so critical. A foot-foot path, as shown in Fig. 4 (on page 38), results in current passing through organs that are vitally important.

        If electricity enters your body through your left hand, it's probably going to try to exit into the ground through your left foot, passing right through your heart along the way.

        Electric current that passes through the chest area is capable of causing death due to asphyxiation or cardiac arrest. With this in mind you must not put yourself in a situation where current could pass from hand to hand or hand to foot. The path of left hand to right foot is the worst case. This is why many texts will tell you to work with one hand in your pocket.
