We had an ultrasound last night and saw the baby :) and the OB said that the babys heartbeat is measuring at 165 beats per min but he said he doesnt let patients hear the hb until after 12 weeks?

Congrats that you got to see the baby and heartbeat!
My first appointment was between 9 and 10 for whatever they were going to do! We just heard our baby's heartbeat the first time today.

Seconds_Behind_Master from SHOW SLAVE STATUS is considered an unreliable measure of Slave lag. mk-heartbeat is often offered as a reliable alternative.
Now mk-heartbeat does not even need the Slave to be running.

Make sure.
In this case, having a heartbeat is useful.
Maybe this will help you, TCP Keepalive HOWTO is merely hung, the socket will remain open .
To build your own heartbeat into your protocol.

Check this link for introduction for Heartbeat in WCF
Basically you use a web page.

Client and WCF service acts as a server.

Just set heartbeat.
If you want simple, go with heartbeat 1; heartbeat 2 went to more-active configuration, including full web service and full proxy service on both(!).
Linux HA is a nice toolset.
