Immediately, at once, right away, instantly.

A very short time as denoted by the time it takes for the heart to beat.

Similar phrase: in the blink of an eye.

Oooh, i miss you in a heartbeat. Oooh, i miss you right away.
(Lyrics: Def Leppard - Miss You In A Hearbeat)

Get the in a heartbeat mug.
It is the kind of horny that tingles in your pussy and it feels like heartbeats
While I was sucking his dick, I was getting heartbeats from my pussy

Get the heartbeat mug.
A very comforting sound to listen to while hugging someone. Also the sound your heart makes.
I fall asleep to the sound of my heartbeat.

Get the Heartbeat mug.
The sound of the heart valves closing and opening in the heart.
I could really feel my heartbeat after running that marathon.
