Building a Program of
Research: 15 Tips
From Doctoral Student to Academic Faculty
1. Pick a topic you are passionate about
from your own clinical experience
Using ECG information to
improve patient care
Improving nursing practice
related to ECG monitoring
2. Determine unsolved problems by
searching the literature
Annals of Internal Medicine 1986
UCSF
Supraventricular Tachycardia (SVT)
Narrow normal QRS complex
SVT with aberrant conduction
Ventricular Tachycardia (VT)
Wide bizarre QRS complex
3. Search the literature on all research
directly related to the topic
Left “Rabbit Ear” Pattern = VT
Lead V1
Right “Rabbit Ear”Pattern = SVT

“Of the conventional ECG leads, the one that
contains the most information…is V1, which
should therefore make the best lead for routine
monitoring. But V1 is inconvenient, since 5
electrodes must remain constantly attached. A
satisfactory compromise, conceived in theory and
confirmed in practice, employs a modified V1.”
Dr. Marriott’s modified V1 (MCL1)

Can wide QRS tachycardia be accurately diagnosed
with V1 criteria when monitoring in MCL1?

4. Contact key scientists for advice
about your research ideas
In developing MCL1, I confirmed
that it matched V1 in an outpatient clinic population. I did
not compare these leads during
arrhythmias, but I would expect
them to be comparable during
wide complex tachycardias.

We did not evaluate
MCL1 in our study.

5. Pick renown mentors for your
doctoral committees

Kathy Dracup, DNSc
Mel Scheinman, MD
6. Publish on your topic (Quals papers) so
your name is associated with the topic
NURSING THERAPEUTICS
• Determine goals
of ECG monitoring
• Diagnose ECG
• Assess patient
(arrhythmia, ischemia,
QT interval)
• Notify MD
• Monitor ECG
• Document
(select appropriate
lead; place electrodes
accurately; evaluate
monitor alarms)
• Administer Rx
• Evaluate efficacy

7. Conduct studies as a doctoral student; publish &
present at national scientific conferences

8. Publish clinical articles as well as research
articles in order to influence practice
9. Publish ALL your dissertation findings

electrophysiology study (EPS)
Key dissertation findings re: wide
QRS tachycardia

Routinely-monitored Lead II was poor
Correctly identifies only 34% of WCTs

V1 was the best single lead; MCL1 should
not be substituted for V1
40% of VTs have different QRS morphology in MCL1 vs V1

12-Lead ECG was best
If it weren’t so cumbersome, it would be great to monitor
all 12 leads

10. Design each subsequent
study to build logically upon
your prior studies
Apply for “friendly” funding for
initial studies (e.g., Sigma Theta
Tau, companies that make related
products, start-up funds from your
own school)
11. Collect data for > dissertation
12. Once you’ve published 4-5
preliminary research articles, think
of the next logical research
question and apply for MAJOR
funding (e.g., NIH).
How does EASI 12-lead monitoring
compare to routine CCU monitoring for
detecting acute myocardial ischemia in
acute coronary syndromes?

ST SMART Study
Study Aim:
Determine whether individuals who call “911”
for chest pain will:
1. have shorter time to treatment
when they reach the hospital
2. have better survival over 5 yrs
if ED clinicians are provided with ECG ischemia
monitoring information from the field
