The New Apple Watch 4 Offers A Built-In App With An Electrical Heart Rate Sensor GMAT Reading Comprehension

Reading Passage Question

The new Apple Watch 4 offers a built-in app with an electrical heart rate sensor heralded as the latest advancement in the field of health. The sensor can theoretically take an electrocardiogram (ECG) of the users, detecting abnormalities such as a rapid or skipped heartbeat in their hearts’ rhythms, typical signs of atrial fibrillation (AFib), a common type of heart arrhythmia, which if not treated can lead to a stroke. The upside of this feature is two-fold according to Apple. Firstly, the data captured by the app, in theory, can help its users and their health care providers to better understand the condition at hand. Physicians of patients with identified heart problems can monitor from a distance how their patients are functioning at all times. Similarly, a patient can gain at least some rudimentary insight into his/her heart health without needing to wait for a scheduled ECG report. Secondly, with such data, the device can help in, the otherwise impossible, early detection of heart problems in people who are unaware of any such issues. This early warning is probably the more significant advantage - it could enable a person to take preventive measures early on and thereby lead to a reduction in possibly fatal heart strokes by indicating such possibilities.

However, there are certain unanswered questions hidden behind these claims. Firstly, the people most likely to use the watch are the younger, healthier, and wealthier people – a group that is the least likely to be at risk of heart disease. Secondly, a significant concern is a false positive. False positives are generated when a healthy person gets a positive result for a disease on a screening test. Data collected by the Stanford Heart study for 266 people who got an “irregular rhythm” notification on the watch indicates that most of such notifications were false positives. Such false positives could lead to further unrequired testing – thus costing money and time, and worse, causing unnecessary anxiety and therefore, have raised doubts on the practical utility of the data collected by the app despite the brave boasts made by the company.

Although the American Heart Association has welcomed the app in Apple Watch 4 with great enthusiasm, it is cautious in not officially endorsing it. There are other functions of the watch that are probably useful and even fun. However, it’s delusionary to believe that a watch will help a user manage his/her heart health, let alone help lose weight or exercise more for that matter.
