Hi doctors! are you able to say what you think about kardia mobile, that portable device that is advertised on television to monitor ones heart/ekg by pressing with fingers on the device?

Portable devices: In general will only make sense if so recommended by treating docs, in this case your cardiologist or primary care doc and looking for specific things, such as arrhythmias. Without proper context the risk of creating unexplainable noise and anxiety is high and outweighing the possible benefit of randomly diagnosing cardiac conditions.
