heart beat in console program

I have a code that implements multi-threaded socket communication with c++, and I want to add an additional heart beat code. However, when the server is waiting for a client message through recv for each thread, how does make run the heart beat? If you let me know the logic or hint, I want to try it.

 
while ((nReceive = ::recv(hClient,
                            szBuffer, sizeof(szBuffer), 0)) > 0)
    {
        puts(szBuffer);
        //Send received strings to all connected clients
        SendChattingMessage(szBuffer);
        memset(szBuffer, 0, sizeof(szBuffer));
    }

 
while ((nReceive = ::recv(hClient,
                            szBuffer, sizeof(szBuffer), 0)) > 0)
    {
        puts(szBuffer);
        //Send received strings to all connected clients
        SendChattingMessage(szBuffer);
        memset(szBuffer, 0, sizeof(szBuffer));
    }

recv enter infiniteloop, and waiting until recevie message from client. i wanna make heart beat code. but It can't since recv. this is all code: https://ideone.com/TWRvnB
