In brief: Electrocardiogram
If the atrial fibrillation is ongoing then an electrocardiogram will show it.
If it only occurs from time to time, then there are different types of monitors that a patient can use at home to record the heart rhythm; this is another type of electrocardiogram sometimes referred to as an event recorder.

In brief: EKG for diagnosis
The first step is to make a diagnosis and an EKG is the easiest way if you are in the arrhythmia.
Otherwise a Holter or an Event monitor would be needed.

In brief: It Varies.
A clue may be irregular pulse on exam. To make the diagnosis officially, some recording of the heart rhythm needs to be made.
This can be via 12-lead ekg, 24-hr holter monitor, or 30-day loop monitor. Sometimes it is picked up by telemetry when in the hospital. Other tests (echo, stress test) might be ordered when the diagnosis of af is made, to look for other related heart conditions.
