Arm triangle choke, side choke, or head and arm choke are generic terms describing blood chokeholds in which the opponent is strangled in between their own shoulder and the practitioner's arm. This is as opposed to the regular triangle choke, which denotes a chokehold using the legs, albeit with a similar mechanism of strangulation against the opponent's own shoulder. An arm triangle choke where the practitioner is on the side of the opponent and presses a forearm into the opposite side of the neck of the opponent is known as a side choke, such as from the kata-gatame hold. The time it takes for the opponent to be rendered unconscious does vary depending on the configuration of the grip and position, although the standard arm triangle is one of the fastest at 7.2 seconds.
