A rough guide from memory so it might not be 100%:

For sender/receiver pair, the heartbeat is the longest period of time the sender will do nothing before it sends a dummy packet to ensure the connection is still alive (the send may fail if the socket/conn has dropped or on the receive of the response). Similarly the receiver waits on a receive with a timeout which is a formula based off the heartbeat value. Therefore the receiver should always be woken with either a heartbeat or a message and if it times out, then it drops the connection. Note the receiver will also send a heartbeat back to the sender as a response to a heartbeat being received.

For client connections, IF a client app is inside an MQGET then it behaves as above, ie sending periodic heartbeats to ensure the connection stays alive. Outside an MQGET the heartbeat does nothing
