To find Ariana's current heart rate based on this measurement, we need to convert the count of 15 beats in 10 seconds to beats per minute.

There are 60 seconds in a minute, so we can use the formula:

Heart rate = (Beats / Time) * 60

Heart rate = (15 / 10) * 60 = 9 * 6 = 54 beats per minute

Therefore, Ariana's current heart rate based on this measurement is 54 beats per minute.
