Helping your patients identify early warning signs.
Apple Watch has powerful sensors that make it the ultimate device for a healthy life. Now with new notifications and the ECG app, it can provide you and your patients with important information concerning their heart health.
Heart rate notifications.
Apple Watch checks for unusually high or low heart rates in the background, which could be signs of a serious underlying condition. This could help you and your patients identify situations which may warrant further evaluation.
If a patient’s heart rate is above 120 bpm or below 40 bpm while they appear to have been inactive for 10 minutes, the user will receive a notification. Patients can adjust the threshold bpm or turn these notifications on or off. All heart rate notifications — along with date, time and heart rate — can be viewed in the Health app on iPhone.
Irregular rhythm notifications.
The irregular rhythm notification occasionally checks for signs of irregular rhythms that may be suggestive of atrial fibrillation (AFib). This feature won’t detect all instances of AFib but may catch something that can provide your patients with an early indication that further evaluation may be warranted.
Irregular rhythm notifications use the optical heart sensor to detect the pulse wave at the wrist and look for variability in beat‑to‑beat intervals when the user is at rest. If the algorithm repeatedly detects an irregular rhythm suggestive of AFib, your patient will receive a notification and the date, time and beat‑to‑beat heart rate will be recorded in the Health app.
The irregular rhythm notification feature is not intended for use by people under 22 years and is not designed for people who have been diagnosed with Afib.
With the ECG app on Apple Watch Series 4, patients who experience symptoms such as rapid or skipped heartbeat, or receive the irregular rhythm notification, can capture an ECG and record their symptoms. This real-world data can enable you to make more informed and timely decisions regarding further evaluation and care.
The ECG app uses the electrical heart sensor built into the Digital Crown and the back crystal of Apple Watch Series 4 to record a single lead ECG similar to a Lead I ECG. The ECG app then provides a result of sinus rhythm, atrial fibrillation or inconclusive, and prompts the user to enter any symptoms such as rapid or pounding heartbeat, dizziness or fatigue. The waveform, results, date, time and any symptoms are recorded and can be exported from the Health app as a PDF to share with a clinician. If the patient notes symptoms that indicate a serious condition, they are prompted to immediately call emergency services.
The ECG app is not intended for use by people under 22 years old.
