Overview

BPM Core is not only a highly accurate smart blood pressure and heart rate monitor, it is the first connected device that can detect, in the comfort of your home, certain valvular heart diseases and atrial fibrillation, both a variety of cardiovascular diseases frequent amongst people suffering from high blood pressure, which can help prevent serious complications from progressing.

BPM Core is our most advanced health device to date, combining medical data traditionally only available in a clinical setting with a seamless design. Along with blood pressure and heart rate monitoring, the three-in-one device records ECG, which is used to identify atrial fibrillation (AFib), a serious form of irregular heart rhythm that can lead to heart failure, fatigue and shortness of breath and is a major risk for stroke.

In addition, it provides an integrated digital stethoscope that can provide early detection of valvular heart disease, characterized by damage to one of the four heart valves that may require surgical intervention to avoid heart failure. Using the form factor of a blood pressure monitor, users can check their results in just 90 seconds along with color-coded feedback directly on the device, and they can view their complete history in the free Health Mate app via Wi-Fi or Bluetooth connection. Data can then be easily shared with doctors. BPM Core features a long battery life of up to 6 months and is rechargeable via micro USB cable.

People with severe blood flow problems, or blood disorders, should consult a doctor before using the BPM Core.
Cuff inflation can cause internal bleeding.
Operational factors such as common arrhythmias, ventricular premature beats, arterial sclerosis, poor perfusion, diabetes, age, pregnancy, pre-eclampsia or renal disease can affect the performance of the automated sphygmomanometer and/or its blood pressure reading.
BPM Core is a precision measuring equipment liable to be understood by lay user but it still should be handled with care.
A long exposure of the device to lint, dust or sunlight might reduce its life time or damage it.
Damaged cuff or sensor might lead to incorrect measurements.
Parts in contact with the skin: cuff and electrodes.
Measurements can be affected by extreme temperatures, humidity & altitude.
