There is a song called “My Heart Goes Pitter Patter” recorded by Simone and Girlfunkle.
There is another (below) by Bia, a young singer from Brazil whose song is “My Heart Goes La La La.”
BIA:
Rod Stewart has a tune called “Rhythm of My Heart”, while Etta Jones sings “There Goes my Heart” (below)
I know a cardiologist whose heart goes pitter patter every time he drinks coffee. The symptom is due to extra heart beats (premature contractions) which give that sensation.
If a heart is stimulated, it might react with a fast beat or an erratic beat. The stimulation can be due to intense emotions including love. Brain related causes result in adrenaline release and activation of the sympathetic nervous system—ie the “flight or fight” reaction; or the stimulation might be due to certain substances such as caffeine, prescription drugs, cocaine, or alcohol. The effects on the heart may be perceived by the patient or may be “silent.”
A violinist came to see me because, before she would go on stage, she would experience tremors in her hands, sweaty palms, and palpitations due to “stage-fright.” a typical emotions-based cause of such symptoms. Other brain related causes of adrenalin release symptoms include fear, anger, severe stress, sudden surprise, threats, and battle. As for love,–if would have to be pretty intense.
The violinist was successfully treated by blocking the effects of adrenaline using a drug called a “beta blocker” which the musician could take as needed, prior to a concert. The drug would not adversely affect the performance as might a tranquilizer, but would enhance it by removing the fear factor.
The cardiac responses to stimulation do not necessarily indicate heart disease. It can happen to healthy individuals. But if you have palpitations, a visit to a cardiologist would be wise. He can order a take-home monitor which can record your electrocardiogram (ECG) when your heart goes pitter patter and it will also make a recording if you have a rhythm disturbance (arrhythmia) without symptoms. In either case, the doctor will be able to see what kind of arrhythmia is causing the symptoms, and then a decision can be made regarding what to do about it.
But no doctor will advise giving up love.
ETTTA JONES:

You can buy an at-home ECG monitor which records an ECG rhythm strip by using an inexpensive small device with an app and a cell phone. You don’t have to be able to read it; the strip can be transmitted and read with a report to your doctor. You just turn it on if you are having symptoms.
