Fitbit’s heart rate sensor saves a life, but its accuracy is questioned. Good news and bad news for wearable maker Fitbit this week. On Monday, news broke of a 73-year-old woman who credits her Fitbit with saving her life. When she noticed an abnormally low heart rate on the device she went to the doctor, who discovered two pulmonary embolisms in her lungs. Fitbit is not a medical device, but this isn’t the first time its been useful in getting someone the right treatment.

Also this week, though, the accuracy of that heart rate sensor was called into question by a new study in the Annals of Internal Medicine. The study found that the sensors weren’t very accurate during strenuous exercise. The study was seized upon by Lieff Cabraser Heimann & Bernstein, the law firm currently suing Fitbit in a class action suit for inaccurate heart rate monitoring.
