the adjusting the first rate of sending the data packets according to the notification information comprises:
adjusting the sampling frequency of the electrocardio data according to the heart rate information in the notification information;
if the notification information is that packet loss and/or error codes exist, adjusting the rate of sending the data packet to a second rate;
and if the notification information indicates that packet loss and/or error codes do not exist, restoring the rate of sending the data packet to the first rate.
7. The electrocardiograph monitoring data control method according to claim 6, wherein the step of receiving a data packet by the receiving device, determining whether a packet loss and/or an error exists according to the data packet, determining the heart rate information of the user based on the digital electrocardiograph data, and generating notification information from the heart rate information and the packet loss and/or the error information comprises:
the receiving device receives a data packet and analyzes the data packet to obtain the electrocardiogram data and a packet serial number and/or a check code;
the receiving device judges whether an error code exists according to the check code;
the receiving device judges whether packet loss exists or not according to the packet sequence number;
the receiving device judges the heart rate information of the user based on the digital electrocardiogram data;
and the receiving device generates notification information according to the heart rate information and the packet loss and/or error code information.
8. An electrocardiographic monitoring data control system, comprising: a transmitting device and a receiving device;
the transmission apparatus includes:
the acquisition module is used for acquiring the electrocardiogram data of the user;
the first sending module is used for generating a data packet according to the electrocardiogram data and transmitting the data packet to a receiving device at a first rate;

the adjusting module is used for adjusting a first rate of sending the data packet according to the notification information;
the adjusting module is specifically used for adjusting the sampling frequency of the electrocardio data according to the heart rate information in the notification information; if the notification information is that packet loss and/or error codes exist, adjusting the rate of sending the data packet to a second rate; if the notification information indicates that packet loss and/or error codes do not exist, restoring the rate of sending the data packet to the first rate;
the receiving apparatus includes:
the second receiving module is used for receiving the data packet transmitted by the transmitting device;
the judging module is used for judging whether packet loss and/or error codes exist or not according to the data packet, judging the heart rate information of the user based on the digital electrocardiogram data, and generating notification information from the heart rate information and the packet loss and/or error codes; the heart rate information is: the heart rate per minute of the user is more than the preset times or the heart rate per minute of the user is not more than the preset times;
the second sending module is used for transmitting the notification information to a sending device; the notification information includes heart rate information.
