Building a Program of Research: 15 Tips From Doctoral Student to Academic Faculty
Using ECG information to improve patient care Improving nursing practice related to ECG monitoring • Pick a topic you are passionate about from your own clinical experience
Annals of Internal Medicine 1986 • Determine unsolved problems by searching the literature UCSF
Supraventricular Tachycardia (SVT) Drug that blocks @ AV node Ventricular Tachycardia (VT) Narrow normal QRS complex SVT with aberrant conduction Wide bizarre QRS complex
Left “Rabbit Ear” Pattern = VT Right “Rabbit Ear”Pattern = SVT Lead V1 Lead V1 • Search the literature on all research directly related to the topic Wellens HJ, et al. Value of the ECG in the differential diagnosis of a tachycardia with a wide QRS complex. Am J Med 1978.
Monitoring Lead V1 Requires Five Electrodes LA RA C RL LL
“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.”
Left “Rabbit Ear” Pattern = VT MCL1 Can wide QRS tachycardia be accurately diagnosed with V1 criteria when monitoring in MCL1? UCSF
In developing MCL1, I confirmed that it matched V1 in an out-patient 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. Hein Wellens, MD Henry J. L. Marriott, MD • Contact key scientists for advice about your research ideas UCSF
Henry J. L. Marriott, MD Kathy Dracup, DNSc Mel Scheinman, MD • Pick renown mentors for your doctoral committees
Publish on your topic (Quals papers) so your name is associated with the topic
NURSING THERAPEUTICS • Determine goals of ECG monitoring (arrhythmia, ischemia, QT interval) • Monitor ECG (select appropriate lead; place electrodes accurately; evaluate monitor alarms) • Diagnose ECG • Assess patient • Notify MD • Document • Administer Rx • Evaluate efficacy POTENTIAL Health Problem ACTUAL Health Problem Health Continuum / Transitions INDIVIDUAL ENVIRONMENT • Genetics • Lifestyle (coronary risk factors) • Psychodynamic factors (anxiety) • Functional status Internal/Cellular External/Social Electrical Activity of the Heart Arrhythmias, ST segment changes of ischemia, QT interval prolongation Normal ECG Abnormal ECG • Ischemia • Acid-base • Autonomic nervous system • Electrolytes • Drugs • Work • Family • Culture • Religion Drew BJ Heart & Lung 1989;18:8-15.
Conduct studies as a doctoral student; publish & present at national scientific conferences How prevalent is inaccurate lead placement?

Publish clinical articles as well as research articles in order to influence practice
WCT’s n=133 SVT n=35 VT n=98 Drew & Scheinman, PACE 1995;18:2194
VT recorded during invasive cardiac 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 MCL1vs V1 • 12-Lead ECG was best If it weren’t so cumbersome, it would be great to monitor all 12 leads UCSF
LA RA V1 V5 RL LL Disadvantage of 12-Lead ECG for hospital monitoring V2 V6 V3 V4 UCSF
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)
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 AnalysisTrial(STAT Study) (1993-96) n=490 Funded by NINR (R01 NR03436) UCSF

ST SMART SynthesizedTwelve-leadSTMonitoringAndReal-timeTele-electrocardiography Prospective randomized clinical trial 2003-2009 Funding:NINR (RO1 NR007881), n=800 UCSF
ST SMART Study Study Aim: Determine whether individuals who call “911” for chest pain will: • have shorter time to treatment when they reach the hospital • have better survival over 5 yrs if ED clinicians are provided with ECG ischemia monitoring information from the field UCSF
Dominican Watsonville San Francisco 100 miles Santa Cruz County
16 Fire Department rigs 13 AMR ambulances ST SMART Study Methods: All EMS vehicles that respond to 911 calls in the county are equipped with portable monitor-defibrillator devices with special study software
ST SMART Study Special Study Software is designed to: • Synthesize a 12-lead ECG from 5 electrodes • Analyze ST segments every 30 secs & automatically transmit an ECG to the destination ED by cell phone if ischemia occurs • If the 1st transmission fails, automatic redialing occurs for a total of 3 attempts UCSF
