ECG : The ECG test involves recording signal from various vectors. The vectors are recorded using electrodes we call leads. Those leads which look at vectors reflecting the lateral wall of the heart are called lateral leads.

See answer: An ekg will have 6 leads on your chest area (called v1 through v6) as well as 1 for each arm and leg. The last 2 leads on the chest (v5-v-6) are called the lateral leads, as well as lead i on the 12 lead ekg sheet.
