His heart is happy like a hummingbird;
She sings all life long.
The patient is in a normal sinus rhythm,
Free, from heart trouble.
His heart is happy like a hummingbird,
Contracting and relaxing.
She sings while the patient is sleeping—
Until it’s time to dream.
His heart is happy like a hummingbird,
Whispering sparkling joy;
Each joyous pulse, very clear and loud,
His EKG, a blissful dancer, on the monitor screen.
