OBHG Education Subcommittee
Chapter 4 Objectives
 Explain
why getting a good medical
history is so important in the AMI patient
 List key elements to OPQRST &
SAMPLE mnemonics for clinical
investigation of possible ischemic
problem
OBHG Education Subcommittee
Importance of Clinical
Presentation
No diagnostic test for acute myocardial infarction
is perfect.
 All medical literature related to ACS recognition
suggest that the clinical presentation of the patient
is of great importance.

Clinical presentation consists of:
•Incident history
•Chief complaints
•PMHX
•Risk factors
•Vital signs
•Assessment findings
OBHG Education Subcommittee
Getting a Good History
 It
is HOW we ask the questions
 Mnemonics (OPQRST) are memory
aids
 Should not be asked literally to a
patient

OBHG Education Subcommittee
Onset
“When did this episode of chest
pressure start?”
“When did this asthma attack start?”
“When did the accident occur?”
OBHG Education Subcommittee
Onset
 Avoid
using closed or leading
questions...
“Did the pain start last night or this
morning?”

Q – Quality
R – Radiation

O
 What
makes it better
or worse?
 Note the position of
the patient
 What they were doing
when it happened?
OBHG Education Subcommittee
Rule # 1 of Questioning
While investigating a chief complaint,
the only words you may use are the
words the patient told you
OBHG Education Subcommittee
Rule # 1
If the patient tells you:
“I’m having a tightness in my chest.”
You would reply:
“When did this tightness start, Jack?”
Rather than:
“When did the pain start, Jack?”
OBHG Education Subcommittee
Provoke
“Jack, does anything you do make the
tightness worse?”
(Inspiration/Palpation/Movement/Position)
“Does anything you do make the
tightness less?”
(Inspiration/Palpation/Movement/Position)
“Jack, what were you doing when this
tightness first started?”

 What
does pain feel
like?
 Avoid closed and
leading questions
 Let the patient have
as many choices as
they like to describe
their “pain”
OBHG Education Subcommittee
Quality
“Jack, what does this “pain” feel
like?”
“What would I have to do to you to
make that kind of “pain?”
OBHG Education Subcommittee
Closed or Leading Questions
“Is the pain sharp or dull?”
“Does the pain kinda feel like a belt
around your chest?”
OBHG Education Subcommittee
What to Ask
– Onset
 P – Provoke
 Q – Quality
O
 Do
they have any
problems or pain
anywhere else?
 Watch for nonverbal
R – Radiation
clues
 S – Severity
 Where is the pain?
 T – Time
 Pain may not “go”
anywhere
OBHG Education Subcommittee
Radiation
Instead of:
“Does it hurt in the center or side of your
chest?”
Try:
“Where does it hurt?”
or
“Can you draw a circle around it?”
OBHG Education Subcommittee
What to Ask

P – Provoke
Q – Quality
R – Radiation
S – Severity
T – Time
O
 Scale
of 1–10
 Make sure you find
out what the worst
pain was.
 Answers of >10
mean it hurts really
BAD!
OBHG Education Subcommittee
Severity
“On a scale of 1–10 with 10 being
the worst pain you’ve ever had,
and 1 being barely any pain at all,
how would you rate your pain
right now?”
“What was the worst pain you have
ever felt?”
OBHG Education Subcommittee
What to Ask
– Onset
P – Provoke
Q – Quality
R – Radiation
S – Severity
O
T
– Time
 The
duration of the
problem
 How long the current
episode has been
going on?
 If prolonged
duration, was there a
recent sudden
severity increase?
OBHG Education Subcommittee
Time
“How long has this recent episode
of chest pressure lasted, Jack?”
“How long did Jack’s seizure last?”
OBHG Education Subcommittee
Tag-ons
 Tag-ons
are extra questions tacked on
to the end of an ordinarily good
question
“Do you have diabetes, hypertension, or
cardiac disease?”
“Are you nauseated?” “Are you short of
breath?”
“Are you having chest pain?” “Is it sharp
or dull?”
OBHG Education Subcommittee
Tag-ons
The best way to avoid a tag-on is to ask
one question at a time and wait for the
answer

pressure in each arm

Apical versus radial pulses
Full auscultated blood pressure
Look for peripheral edema
OBHG Education Subcommittee
The 12 Lead ECG
 Best
“early” confirming diagnostic test
 Should be performed on any patient
with a “pulse and problem” between
nose and naval that is suspicious for
cardiac
 Should be acquired and triaged in less
than 10 minutes arrival on scene
