A pulse is typically counted per heartbeat, which varies from person to person but averages around 60-100 beats per minute at rest. To convert this to pulses in one second, you would divide by 60 (for 60 seconds in a minute), resulting in roughly 1-1.7 pulses per second.
That may depend on how active or stressed you are, but at rest, the normal heartbeat is between 60 and 100 beats per minute.
60-100 beats per minute. :)
If you are refering to their performance on Live in the LBC, then yes, Synyster Gates messed up on his solo during Second Heartbeat.

You must go for a second opinion. When the fetal heartbeat is present there must be a fetus. Sometimes a woman can have an ectopic pregnancy and the fetal heartbeat can be heard, but the fetus is not in utero. It is in the fallopian tube. This is a serious condition so you should definitely get a second ultra sound. ASAP!!!
