Simple Cardiac Screening of NCAA and USAC Collegiate Athletes Using Smartphone Electrocardiogram    Luck, JC., Baquero, GA., Luck JC. Penn State College of Medicine, Hershey, PA,     Lees-McRae College, Banner Elk, NC  The recent development of modern smartphone technology is quickly revolutionizing the medical field. For the last 100 years, the standard 12-lead electrocardiogram (ECG) has been the primary tool in clinically diagnosing cardiac disease and arrhythmias in patients. In large diverse populations, new smartphone technology could provide a new platform for a cost effective, efficient, and accurate cardiac screening tool. The AliveCor ECG device (AliveCor, San Francisco, CA) allows wireless acquisition of a single-lead ECG on any iOS or Android device. Results can be downloaded and reviewed using an internet browser. PURPOSE: In this feasibility study, we screened competitive collegiate athletes using a smartphone ECG. We assessed the rate and rhythm pre- and post-exercise. We compared the smartphone ECG with the standard 12-lead ECG tracings. METHODS: A total of 20 subjects (21±4 yrs, 10 male, 10 female) provided written informed consent. A standard 12-lead ECG was obtained at rest followed by a smartphone generated 12-lead ECG. A one-minute smartphone ECG of lead I was recorded pre-exercise. Exercise was completed at ≤80% of perceived rate of exertion (PRE) or ≤80% of maximum predicted heart rate (MPHR). A one-minute smartphone ECG was acquired within ten seconds of terminating physical exertion. All ECGs were de-identified and interpreted by a board-certified cardiology electrophysiologist. The main outcome measure was the difference in voltage (mV) between the smartphone ECG and the standard 12-lead ECG. RESULTS: Smartphone ECG tracings were consistent with the standard 12-lead ECG in all 20 subjects. (P = 0.08±0.1 mV, Q = 0.03±0.4 mV, R = 2.19±0.8 mV, S = 0.51±0.5 mV, T = 0.38±0.4 mV). No critical cardiac conditions were detected in either the smartphone ECG or standard 12-lead ECG (interpretation was normal sinus rhythm 40%; sinus bradycardia 60%). The observed mean HRmax was 176±35 bpm; HRrecovory was 112±48 bpm; absolute decrease in HR was 63±32 bpm; percent MPHR was 88%. CONCLUSION:  The smartphone ECG compared favorably with the 12-lead ECG. This protocol can be easily adapted to enhance the preseason screening process carried out by athletic trainers.
