AliveCor Announces Smartphone Electrocardiogram Demonstrates Accuracy in Monitoring Patients' Heart Health
BOSTON & SAN FRANCISCO --(Business Wire)--
AliveCor,
the developer of a breakthrough mobile electrocardiogram (ECG) recorder,
today announced results from a study that demonstrated the accuracy of
the company's iPhone (News - Alert)-based device, by comparing its Lead I to Lead I
from a conventional 12-lead ECG. The study found that the iPhone-based
event recorder is an accurate clinical tool for ECG assessment and could
prove to be a new tool for allowing immediate recording and analysis of
an ECG rhythm.

The AliveCor smartphone
ECG is an innovative, investigational medical wireless device which
incorporates electrodes into a wireless case that snaps onto the back of
a smartphone. The device allows for wireless single-lead recording of
rhythm strips (from 30 seconds to continuous reading) that are stored
securely in the cloud and then within the app itself. The ECGs are
wirelessly uploaded for immediate interpretation anywhere using simple
web browsers. The AliveCor smartphone ECG is designed to work in
conjunction with a range of mobile platforms, including iPhone, iPad and
Android (News - Alert) devices.
The resuls from this study were presented today in a poster
presentation in the Innovation Abstract category at the Heart Rhythm
Society's 33rd Annual Scientific Sessions in
Boston (Abstract # 12-IA-9662-HRS) by Dr. Paul Garabelli of The
University of Oklahoma Health Sciences Center. The authors of the
abstract also include: Dr. David Albert, Founder & Chief Medical Officer
of AliveCor and Dr. Dwight Reynolds, Chief of Cardiology at The
University of Oklahoma Health Sciences Center.
"We are encouraged by the continued validation of AliveCor's innovative
technology, which upon anticipated marketing approval will improve early
diagnosis of arrhythmias and overall public awareness of health
metrics," commented Dr. Albert, inventor of the technology. "We envision
that our technology will significantly benefit patients who need
consistent and more convenient monitoring."
Twelve-lead ECGs (Mac5500, GE Healthcare) with gel-based electrodes and
Lead I ECGs (AliveCor ECG, AliveCor) were recorded in 67 patients. Five
patients with pacemakers had the iPhone placed directly on the chest to
record a V3-V4 rhythm strip, and two physician reviewers cross-validated
these strips for pacing spikes. All recordings were performed with the
iPhone in Airplane mode so no radio frequency interference was generated.
In 62 patients, two physicians found the QRS morphology to be the same
between the two devices, though the iPhone-based ECG had more baseline
noise than the standard ECG (Figure 1B). The mean/SD of the R-wave
amplitudes for the standard and iPhone recordings respectively were
0.77/0.24 (mV) and 0.78/0.24 (mV), P<0.0001. In five patients with
pacemakers, pacing spike artifacts were clearly identified in all five
enabling verification of pacing capture (Figure 1C).
About AliveCor
AliveCor provides powerful, low cost, easy-to-use mobile devices, apps,
and data to medical professionals and patients (be they human or animal)
that empowers the screening, diagnosis, and monitoring of life-altering
diseases. AliveCor has developed a clinical-quality ECG recorder that
enables patients to monitor their heart health anywhere, at any time and
provides physicians with a more comprehensive assessment. The AliveCor
smartphone ECG is designed to work in conjunction with a variety of
mobile platforms, including iPhone, iPad, and Android devices.
In 2011, AliveCor raised $3.3M in a Series A financing with Burrill &
Company, Qualcomm (News - Alert) Incorporated, acting through its venture investment
arm, Qualcomm Ventures, and the Oklahoma Life Science Fund. The company
is currently underway in clinical studies at the Oklahoma University
Health Sciences Center and is seeking regulatory clearance for marketing
approval of its iPhone ECG Case and Android ECG Card. For more
