The invention discloses a burst transmission method for an urgent service in a wireless body area network. A communication link tree network is used for distributing time slots in a sequence from bottom layer nodes to top layer nodes according to a network structure. The time slots are formed by an access time frame t0 and an access time frame t1 in the process of processing the urgent service and a time frame t2 in the process of transmitting the service. When the urgent service exists in a node, a time slot expropriating request begins to be broadcast in a next time slot. The t0 time frame of the current time slot is monitored, if the time expropriating request is monitored, priority is judged on the node where the urgent service occurs, the urgent service with high priority is transmitted in the t2 time frame of the current time slot, whether the urgent service is transmitted to a root node or not is judged, if not, the time slot expropriating request continues to be sent in the next time slot, and the steps are repeated until the urgent service is transmitted to the root node in a relay mode.
