A bug discovered in Apple Watch Series 4 is reportedly crashing the device and causing it to get stuck on re-boot loops, the media reported.

“The Watch reboots itself repeatedly, as long as the ‘Infograph Modular’ face is active with the ‘Activity’ complication. Every time the device boots, it tries to load the complications again, fails and restarts. This continues indefinitely until the watch runs out of power,” 9To5Mac reported late on Sunday.

The “Activity” feature is responsible for sketching a timeline graph of the current day, showing hour-by-hour data for calories, exercise minutes and stand hours.

The maximum complaints are coming from Australia where people have experienced the change in daylight saving time, which may have caused the “Activity” feature not been able to draw its graph.

“Until Apple provides specific steps, we would recommend leaving the Watch alone and waiting it out. Do not bother putting it back on the charger as it will just continue to drain its battery and reboot,” the report added.

Doctors Feel Blessed on New Heart Health Tools in Apple Watch in India

The medical fraternity on Friday welcomed the arrival of the ECG app and irregular rhythm notification feature on Apple Watch for users in India, stressing that it will make people more aware about their heart health.

Although the Apple Watch will not provide a final conclusion into whether a person is actually suffering from Atrial fibrillation (AFib) — irregular heartbeat that can lead to blood clot formation in the heart which then embolises to the brain causing stroke — the readings will make more Indians consult their physicians about their heart health, doctors feel.

Although accurate worldwide estimates are lacking, calculations suggest that over one per cent of the adult population is affected in the developed world, wrote Vijay Bohra, Gautam Sharma and Rajnish Juneja from Department of Cardiology at All India Institute of Medical Sciences (AIIMS) in their research.

“In our country, there is virtually no data on AF (AFib), most of the data that has been derived is from international studies with an Indian cohort,” the trio wrote, adding that there is “indeed a dearth of data on epidemiologic outcomes in patients of rheumatic AF in the country leading to inconsistent practice patterns as regards medical therapy, especially oral anticoagulation”.

According to Mukesh Goel, Senior Consultant, Cardio Thoracic & Vascular Surgery, Indraprastha Apollo Hospitals, AFib is more prone in those patients who are predisposed to have AFib and stroke.

“Generally, we do holter monitoring (a small, wearable device that keeps track of your heart rhythm) or extended holter monitoring which is a 24-hour ECG monitoring system, to detect AFib in the patients. However, it is not always necessary that these 2-3 episodes of AFib will occur during the time of the holter monitoring,” Goel told IANS.

Hence, in such cases, Apple Watch will be playing a vital role in detecting AFib in time, he added.

“Having said this, a person must wear the Watch both during day and night so that the occurrence of AFib is detected well in time,” Goel suggested.

New electrodes built into the back crystal and Digital Crown on Apple Watch Series 4 or later, work together with the ECG app to enable customers to take an ECG similar to a single-lead reading.

To take an ECG recording at any time or following an irregular rhythm notification, hold their finger on the Digital Crown. As the user touches the Digital Crown, the circuit is completed and electrical signals across their heart are measured.

After 30 seconds, the heart rhythm is classified as either AFib, sinus rhythm or inconclusive.

Sanjiv Bhardwaj, Associate Director, Department of Interventional Cardiology at Jaypee Hospital Noida said that smartwatches and fitness bands are now playing a vital role in updating the users about their heart health and the possible risk factors related to cardiovascular diseases.

“Advanced and modern features like an ECG app and irregular heart rhythm monitor will surely be a huge help to the users. They can easily get the notifications about their heart rhythm and its classification in less than a minute.

“The results can be shared with the doctors so that any major complication can be averted,” Bhardwaj told IANS.

With watchOS 6, the irregular rhythm notification feature on Apple Watch Series 4 and the upcoming Series 5 on September 27 will use the optical heart sensor to occasionally check the user’s heart rhythm in the background for signals of an irregular heart rhythm that appears to be AFib.

If irregular heart rhythm such as AFib is identified on five rhythm checks over a minimum of 65 minutes, a notification will be generated to alert the user.

“Technology is moving at lightning speed and Apple is surely abreast with it. Rhythm identification via the phone is no longer a dream,” said Aparna Jaswal, Associate Director, Cardiology & Electrophysiology, Fortis Escorts Heart Institute, New Delhi.

“Apple Watch will help identify AF and rhythm disorders and this will surely help in early identification of disease,” she said.

The irregular rhythm notification feature was recently studied in the Apple Heart Study. With over 400,000 participants, the Apple Heart Study was the largest screening study on atrial fibrillation ever conducted. (IANS)
