If you're talking about heart rate, yes 168 beats a minute is pretty high, but wouldn't be too weird right after a crying spell, a temper tantrum, or running across the yard. If it didn't slow after a couple of minutes, it might be concerning, though. A normal heart rate for an infant is 120-160 beats/ minute and that slows gradually through the lifetime until adulthood, when it is about 60-75 normally. At 18 months it won't have slowed a lot, but should be under 160 at rest.
No, it is not high.
Hummingbird's heart rate can reach as high as 1,260 beats per minute.
The normal heart rate of a 5 year old is between 75 beats per minute and 115 beats per minute. At 120 beats per minute your child is probably excited about something or has just ran or walked for periods of time.
It might be a little high but not dangerously high.
Hummingbirds are one of the smallest birds on earth. They eat a nectar of sugar and water when fed by humans. Their heart rate is typically 50 to 180 beats although it can be as fast 1260 beats. The wings beat at a rate of 10 to 15 beats a second.
A hummingbird's heart can beat up to 1,260 times per minute. Its heart makes up 2.5% of the creature's total body weight.resting hummingbirds hearts beat at 250 (BPM) beats per min. Or 1200 beats per minute (BPM) when feeding.In torpid hummingbirds, the heart rate can drop to 50-180 per minute.250 beats per minute resting 1200 beats per minute while feeding or flying1200 beats per minute. Hummingbirds have a bigger heart size then every other bird in the world.
The pulse rate during adolescence can be anywhere from as low as 50 or 60 beats per minute to as high as 90 or 100 beats per minute. It depends on the individual.
At rest the normal heart rate of a newborn is 100 to 160 beats per minute; between the ages of 1 and 10 is 60 to 140 beats per minute; and 11 to 17 is 60 to 100 beats per minute. You should contact a doctor if the heart rate is higher or lower than this.

A human heart beats about 100,000 times a day. The resting rate can be around 60 to 90 beats per minute in children and adults. The maximum rate is around 200 in children, which can be dangerously high in adults.
That is pretty high, even for someone on methotrexate. You definitely need to get that checked with your doctor.
