iPhone's Vision of Medicine's Future

Castro, Harvey MD

doi: 10.1097/
DOC Approved

Dr. Castro is an emergency physician, the CEO of Deep Pocket Series (, and the creator of several iPhone apps, including IV MEDS, Stroke Scale, A Shockable Ringtone, Drug Seeker, and 1st Follow Up.

Apple recently filed a patent for the iPhone that will enable users to monitor their heartbeat and perform biometrics by touching the phone. The idea is that the iPhone can detect who is holding it based on the heart rhythm. The patent also says it could determine the user's mood, and be personalized for different users.

This heartbeat sensor will block unknown users from accessing the phone and any confidential information stored on it. According to the patent, the phone would compare portions of the user's heart rhythm and relative peaks in the EKG. I would think an aging or diseased heart or certain medications would affect this, but I'm sure Apple has figured all this out. If the patent is granted, it will be interesting to see patients coming into the ED with their iPhones showing that they are in afib or SVT.
