Atrial fibrillation (AF), the most common cardiac arrhythmia, affects more than 3 million people in the United States and 3–5% of people over 65. The prevalence of AF continues to increase, and projections forecast the number afflicted with AF to increase to 15 million by 2050.1 Although AF can affect quality of life and cardiac status, the largest risk is thromboembolic stroke. Compared to those in normal sinus rhythm, the risk of stroke is at least fivefold.2 Much of this risk can be negated with the use of anticoagulants such as warfarin. However, warfarin is often troublesome for patients secondary to vacillating INR values, frequent INR checks, dietary restrictions, and interactions with other medications.

Beaumont has been a longstanding leader in cardiovascular care and technology. Thanks to the generosity of Max and Debra Ernst and their family, the Ernst Cardiovascular Center became a reality. The new 4,537 square-foot Center, which opened in Fall 2010, offers multidisciplinary clinics for atrial fibrillation, heart valve disease, congestive heart failure, adult and student cardiovascular screening and complex aortic disease.

Dear Readers,
A 22-year-old man is referred to an electrophysiologist after family members were diagnosed with long QT syndrome (LQTS). Several paternal relatives had died from a cardiac arrest at a young age, including his aunt, grandfather, and two of his second cousins. The most recent death was in a 27-year-old second cousin, after which relatives were advised to see a physician. The patient has never had syncope, presyncope, rapid palpitations, or other cardiac symptoms. He is otherwise healthy and not taking any medications. His physical examination is normal. The patient recently had an electrocardiogram, an exercise stress test, and an echocardiogram that were reportedly normal. Another electrocardiogram was performed in the office and is shown below. The sinus rate was 55 bpm. The T-wave appears slightly abnormal with possible notching in lead II, but the QT and QTc intervals were 434 and 415 msec, respectively.

What is the size of your EP lab facility and number of staff members? What is the mix of credentials at your lab?
The EP lab at Mount Carmel Health System is a system-based department that has responsibility for five labs at three facilities: Mount Carmel East in Columbus, Ohio, Mount Carmel West in Columbus, Ohio, and Mount Carmel St. Ann’s in Westerville, Ohio. We have 19 RNs: Ryan Bailey, RN, BS; Teri Balser, RN; Katrina Bratton, RN, BSN; Laurie Bussey, RN; Jody Cain, RN; Rhonda Edwards, RN, BSN; Lori Fravel-Petruska, RN, BSN; Jennifer Harvey, RN, BSN; Stephanie Henery, RN; Molly Hoover, RN; Sonya Kennedy, RN; Lois Kozlowski, RN; Mariann Menter, RN; Brian Reymond, RN, BSN; Anne Rorapaugh, RN; Elizabeth Siferd, RN; Meggan Stiltner, RN, MSN; Doris Will, RN; and Joey Young, RN, BSN. We have three RTs: Lee Crum, RT, BA, Jean DiDonato, RT, and Kevin Odle, RT. There are seven electrophysiologists: Dr. F. Kevin Hackett, Dr. Ken Lee, Dr. Kamel Addo, Dr. Shaialesh Patel, Dr. Charles Noble, Dr. Jiang Cui, and Dr. Christopher Frank. We also have three interventional cardiologists who implant devices: Dr. Jack Stanko, Dr. Tyrus Frerking, and Dr. Keith Pattison.

On December 14-15, 2010, the Heart Rhythm Society (HRS) held its inaugural research forum to identify opportunities and challenges to advancing electrophysiology research in the United States and abroad. In this feature interview, we speak with Douglas L. Packer, MD, FHRS, President of the Heart Rhythm Society, to learn more about the research forum.

Tell us about your medical background and how you came to work in the field of electrophysiology. What interested you about this field?
I first became interested in electrophysiology as an undergraduate at Washington University in St. Louis. After my first year of college, I worked in a laboratory in the cardiovascular division, where my research mentor introduced me to clinical cardiology. I have always had a fondness for physics, and I particularly like conceptual disciplines. Electrophysiology was a natural fit for these interests, and it was at this time in my life that I realized that the relatively new, technologically advanced field of EP would be the perfect career for me.
Diagnostic Genetic Testing for Arrhythmias: Learning the Most Familiar Gene Mutation Codes

I often wonder if as clinicians, we are thinking globally in our treatment of arrhythmias? Are we treating these as individual problems? Most electrical disturbances for the most part have an underlying cause that has made them surface. At the Cleveland Clinic, we have been changing the way we treat certain arrhythmias with the conventional treatment of these diseases.

In this next installment of the ECG 101 section, the author describes wide complex tachycardias, which can be a challenge to diagnose based on the 12-lead ECG alone.
Case Report
A 20-year-old male presents to the Emergency Department with complaints of a sudden
onset of palpitations. He states he was studying for his final exams when he had palpitations associated with mild chest discomfort and shortness of breath. He drank two glasses of water without relief and finally called 911. Per the record, the paramedics found him to be agitated and anxious. His blood pressure was 110/80 and his pulse was 190 beats/min. His ECG at the time of presentation showed a wide complex tachycardia (WCT) with a heart rate of 200 bpm (Figure 1).

Tell us about the components of the AliveCor iPhone ECG.
The iPhone ECG fits the Apple iPhone 4. There are 2 components. There is a case for the iPhone 4 that is as small as any of the cases you would buy to protect your iPhone. It is very sleek and slim, and on the back, it has 2 stainless-steel electrodes about 2.5 inches apart. There is also an app that runs on the iPhone. By combining the iPhone app and the case together, you have a real-time, single-lead, cardiac lab recording quality ECG device that comes at an extremely low cost.
