My iPhone's slender $100 attachment may one day save my life. Possibly, it already cut America's healthcare expenditures by thousands of dollars. The AliveCor Kardia, invented by David Albert, enables my iPhone to perform a clinical-quality electrocardiogram in 30 seconds.
Cardiologist-author Eric Topol says the smartphone may become the most important diagnostic medical device of this century. Earlier this year, I spoke to 250 health plan administrators in Phoenix. I explained how AliveCor benefits patients who have experienced atrial fibrillation (a-fib), an intermittent cardiac arrhythmia that, if left untreated, can spawn a stroke.
