AliveCor Touts Benefits Of Smartphone ECG


AliveCor, which markets a mobile electrocardiogram (ECG) recorder for smartphones, announced results from a study that demonstrated the real-world effectiveness of simple heart-rate monitoring for users.

The eight-week study, “iPhone Rhythm Strip: Clinical Implications of Wireless and Ubiquitous Heart Rate Monitoring,” enrolled 54 participants to determine how they use the device.

After using the device, 24 percent of subjects reached out to their private physicians for a consultation and 16 percent felt that they discovered a health condition previously unknown to them. Seventy-five percent of participants requested continuation of the device usage after the eight-week study period. Thirty-three percent felt that they were more health conscious after participating in the study and 88 percent thought that the device was transmitting accurate information. Participants indicated that they found the portability, ease of use, and the form factor to be key aspects of the device that were most conducive for use.

The AliveCor smartphone ECG incorporates electrodes into a wireless case that snaps onto the back of a smartphone, allowing for wireless single-lead recording of 30-second rhythm strips that are stored securely in the cloud and the device itself. The ECGs are wirelessly downloaded for immediate interpretation using a variety of browsers. The AliveCor smartphone ECG works with iOS and Android devices.

The results from the study were presented at the American College of Cardiology 61st Annual Scientific Sessions in Chicago by Dr. David Albert, founder and chief medical officer of AliveCor.

AF Stat Releases New Smartphone App


AF Stat has released updates to its AFib Educator, a free smartphone app and desktop widget designed to help health care providers better explain atrial fibrillation (AFib) to their patients.

AFib is the most common form of irregular heartbeat, affecting an estimated 2.5 million Americans

The AFib Educator 2.0 visually demonstrates the importance of the management strategies of clinical treatment guidelines: rate control, rhythm control and stroke prevention.

New animations show patients important potential consequences of AFib, including stroke risk and heart remodeling. One animation shows how a blood clot can form and flow to the brain, causing an AFib-related stroke; while another illustrates heart remodeling, in which the heart changes size and shape as a result of being in AFib over time.
