In general, the larger the animal is, the slower is its resting heart rate. Great whales (the
largest animals) have resting heart rates around 7 beats per minute (bpm), according to
Gordon Ramel (http://www.earthlife.net/mammals/blood.html), who also notes that some
smaller animals have even lower heart rates while hibernating (for example, the European
hedgehog, which slows from 200-280 bpm while active to around 5 bpm while hibernating).
(It's a good bet that there is some other animal with an even slower hibernating heart rate --
you might want to research this question a bit more).
Cold-blooded animals slow their hearts dramatically at low temperatures. At
http://www.peteducation.com/article.cfm?cls=17&cat=1848&articleid=295
you can read about how crocodiles, for example, slow their hearts from 24-40 bpm
in daytime (28C) to 15-20 bpm at night (18C), and to as slow as 1 bpm at 10C (which
is pretty cold for a croc).
At the other extreme, shrews have an average heart rate of 800 bpm and a peak rate
over 1300 bpm.

Leopards have a resting heart rate of 90 to 140 on average
i think it does have a slow heart beat!
Valves have nothing to do with heart beat The pacemaker of the heart controls the heart beat
If you fix your eyes on the color red, your heart will beat faster.

runing
Snakes
Running.
doing any excersice for 20 minutes or more, no less should increase your heart beat to the max. eg, jogging then sprinting.

Yes! A Blue Whale has a heart beat of 8 times per minute. Have you ever picked up a rabbit and felt his/her heartbeat? Some Rabbits have a heart beat of 300+ times per minute. A mouse can have a heart beat of 600+ times per minute.
if u mean what animal has the fastest heart beat rate, then the answer is the Amethyst Woodstar Hummingbird because it is the smallest vertebrate around. The smaller the animal the faster the heart rate, this is because when the heart beats it gives blood to the body, if the body is large, it would take time for the blood to go around and come back and beat again, however if the body is small, in less than a second the blood may come and go several times. The proof is that a grown man's heart beat rate is at 72/min in average. While the mouse's is 400/min in average. Look at the difference in the size of the body.
Leopards have a resting heart rate of 90 to 140 on average
etruscan shrew has can have a heart rate of up to 1511 bpm
The fastest alive land animal is the cheetah. The fastest alive water animal is the sailfish. The fastest in air is the peregrine falcon. :)
It can beat at any rate...it depends what time of animal you are talking about, humming birds would have a much faster heartbeat versus an elephants' would be slower ;)
