What is Diagnostics?
Diagnostics is a bridge subject,
this subject is in a position
between
preclinical medicine
and clinical medicine.
The contents of diagnostics
include
symptomatology
※ inquiry
※ physical examination
laboratory
electrocardiogram
ultrasonic
Inquiry
history taking
by questioning to take a history
★The importance of inquiry
for example:
peptic ulcer
gastric ulcer
duodenal ulcer
Peptic ulcer has three clinical
characteristics
chronicity several years
periodicity special seasons
late autumn
early spring
rhythmicity of epigastric pain
pain meal relief duodenal ulcer
meal pain relief gastric ulcer

2 Chief Complaints
The chief complaints should
constitute in a few simple
words: symptom(s) plus time.
The main reasons why the
patient consults a doctor.

★The methods and skills of

introduce yourself and explain

the body of interview
chief complaints
present illness
past medical history
the end of interview
2 The sequence of inquiry

headache before?

If the patient tell you I
have hypertension,
you should ask patient
