According to the embodiment, the invention discloses a method and equipment for transmitting cardiac sound data. The method comprises the following steps: collecting cardiac sound signals by virtue ofa sensor at a configurable sampling frequency; and in accordance with configurable signal processing parameters, processing the collected cardiac sound signals, so that the cardiac sound data is generated, wherein the cardiac sound data includes at least one of a heart rate, a first cardiac sound amplitude, a second cardiac sound amplitude, diastole time limit and systole time limit. The method further comprises the following steps: packaging the cardiac sound data into a data package, and transmitting the data package to electronic equipment by virtue of a low-power-consumption Bluetooth channel, wherein the data package at least includes identification fields and cardiac sound data fields. According to the embodiment, the cardiac sound signals are collected and processed by virtue of the configurable processing parameters, and the cardiac sound data package in a preset format is transmitted through low-power-consumption Bluetooth, so that the cardiac sound data can be transmitted efficiently with low power consumption.
