Your heart is connected with your pancreas via the autonomic nervous system. As people develop the early stages of diabetes, their pattern of heart rate variability shifts. In 2015, the Framingham Heart Study showed that high resting heart rate and low heart rate variability predicts who will develop diabetes over a 12-year period. In 2005, the ARIC study showed that heart rate variability declines faster in diabetics than non-diabetics over a 9-year period.
DeepHeart, a neutral network, took the Cardiogram data and concluded it offered an accuracy rating of 85 percent.
14,011 users of Cardiogram for Apple Watch and Android Wear were recruited into UCSF’s Health eHeart Study. Then, 33,628 person-weeks of health sensor data was used to train a deep neural network by presenting it with samples from people with and without diabetes, hypertension, sleep apnea, atrial fibrillation, and high cholesterol.
