This lecture is about
the heart rate in
pediatric patients looking at
normal ranges and abnormalities.
My name is Hannah
Bellsham-Revell and I'm one of
the pediatric cardiologists at
Evelina London
Children's Hospital.

There are various ranges
available and through
this range of lectures
I will be using the UK PEWS
to look at these ranges.

In terms of values of
normal heart rate at
rest for children,
these are grouped into
four main age groups.
For naught to 11 months,
we generally accept
110-150 per minute.
In 1-4 years,
90-140 per minute, 5-12 years,
80-120 a minute,
and more than 13 years is like
an adult at 70-100 per minute.
It is however, very
important to look
at trends, not just
isolated numbers.
You may see a response to
treatment and heart
rate response.
For example, fast heart
rate that reduces in
sepsis once you give
fluid and antibiotics.

When looking at higher
than normal heart rates,
a higher than normal heart
rate is called tachy,
which means fast, and cardia,
which means heart
rate, so tachycardia.
Physiological tachycardia
can be normal.
This could be, for example,
after exercise, if someone
is anxious, if they have pain,
or if there is stress,
and this should normally settle
once the trigger has stopped.
It could be a physiological
response to pathology.
For example, in infection,
dehydration, blood
loss, or fever.
However, it could be an
abnormality of the heart rhythm
which could be related to
an abnormality of the
heart's electrical wiring.
