“Have you experienced any heart palpitations?”
You're a doctor. A patient is complaining about a pain in her chest. You want to know what other symptoms she's experienced, to find out if there's a problem with her heart.
Have you experienced any heart palpitations?
Doctors and nurses use this kind of expression when asking about a patient's symptoms. For example:
Have you experienced any shortness of breath?
Have you experienced any trouble urinating?
The doctor or nurse can also ask "Have you been experiencing any ___?" for symptoms that are ongoing, like:
Have you been experiencing pain in your lower back?
A patient can also speak this way toward the doctor:
I've been experiencing some memory loss.
And finally, you can use "experience ___" for other problems that are not health-related. For example, on an airplane:
Ladies and gentlemen, we're experiencing some turbulence. Please return to your seats and fasten your seatbelts.
Problems with your heart beating too quickly, skipping a beat, or not beating with a steady rhythm are called "heart palpitations".
You use the phrase "heart palpitations" when describing this feeling to a doctor or nurse, or when telling someone about your medical problems.
If your heart beats strangely because of a strong emotion like fear or excitement, it's more common to use phrsases like "my heart was racing" or "my heart skipped a beat".
