Atrial Flutter is characterized by rapid depolarization of a single atrial focus at a rate of 250-350 BMP
no its not a normal rate would be about 70-90 beats per minute
A march would 70-80 per minute.
Oh, dude, math time! So, if the heart beats 72 times in a minute, that means it beats 18 times in a quarter of a minute. Just divide 72 by 4 and boom, you got your answer. Like, it's simple math, but hey, your heart's doing all the hard work anyways, right?
Seriously? 30/15=2 21x2=42... but the pulse is the number of beats in a minute so it would be 42x2 and thus her pulse would be 84.
It beats 75-85 beats per minute. In 45 seconds it would beat about 65 beats.
The most accurate would be for one full minute so you can get the beats per minute, but you can go for half a minute and then multiply times two to get beats per minute.
At 60 beats per minute (BPM), there are 60 quarter notes (crotchets) in one minute. Since each quarter note contains 2 quavers (eighth notes), you would have 120 quavers in 60 beats per minute.
would a butterflys wing not flutter
Any where between 70 and 80 beats per minuteThe average pulse for an adult is anywhere from 60 to 100 beats a minute. If a person has a lower heart beat their heart be would be 40 to 100 beats a minute.
A normal resting heart rate would be 60 - 100 beats per minute.
If you are referring to humans, it depends. The average healthy person's heart beats between 60-80 beats per minute. A:72 beats per minute and 2.5 billion times in a lifetime (66 years). :]
At a rate of 200 to 300 beats per minute, the total for an hour would be 12000 to 15000 beats.
