What is BioTracker PPG?

The new Health Watch is equipped with BioTracker PPG - a self-tracking optical sensor that can provide accurate 24-hour heart rate monitoring

heart rate monitoring

A heart rate monitor (HRM) is a personal monitoring device that allows one to measure/display heart rate in real time or record the heart rate for later study. It is largely used to gather heart rate data while performing various types of physical exercise.

with a high sampling rate of 50 Hz and low power consumption. With the help of a built-in ECG sensor, it allows measuring accurately the heart health of its owner.

What is Amazfit Biotracker?

This smartwatch series includes a newly upgraded biological optical tracking sensor, the BioTrackerTM 2, that supports measurement of blood-oxygen saturation, sleep quality monitoring and heart rate tracking.

What is PPG ECG?

First of all, ECG is a measurement of the electrical activity of the heart, using multiple electrodes. Whereas, PPG is an optical measurement of arterial volume, just using a single photodiode. In both cases, you can use the information to determine a patient's heart rate.

What is PPG heart sensor?

Abstract. Photoplethysmography (PPG) is an uncomplicated and inexpensive optical measurement method that is often used for heart rate monitoring purposes. PPG is a non-invasive technology that uses a light source and a photodetector at the surface of skin to measure the volumetric variations of blood circulation.

How accurate is PPG?

The PPG-accuracy, defined as the proportion of PPG measurements within 100 ms of ECG measurements, was 94.6% (95%CI 94.1–95.1). The accuracy within 50 ms range was 89.2% (95%CI 88.5–89.9).

What is PPG blood pressure?

In recent years, extensive studies have been conducted on non-invasive and cuff-less BP estimation using photoplethysmography (PPG) signals. PPG is a non-invasive optical method for measuring blood volume changes per pulse. In other words, the PPG waveform represents the mechanical activity of the heart.

Is PPG better than ECG?

ECG technology is considered the gold standard when measuring HRV. Unlike PPG, which is an indirect method, ECG records the heart's electrical activity at its source, which makes it more reliably accurate at the millisecond level.

How does a PPG work?

PPG makes uses of low-intensity infrared green (IR) light. When light travels through biological tissues it is absorbed by bones, skin pigments and both venous and arterial blood. The voltage signal from PPG is proportional to the quantity of blood flowing through the blood vessels.

Is pulse oximetry the same as PPG?

Photoplethysmography (PPG) is an optical technique that measures blood volume variations. The main application of dual-wavelength PPG is pulse oximetry, in which the arterial oxygen saturation (SpO₂) is calculated noninvasively.

What is a normal pulse rate?

A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats per minute.

How do you calculate heart rate from PPG?

Heart rate is calculated by counting the number of systolic peaks per minute. Figure 6 shows the systolic peaks and peak-to-peak interval of a PPG signal measured by the NeXus-10 MKII device in the dry environment.

What is difference between heart rate and ECG?

Heart rate gives you a measurement of beats per minute. But an EKG measures the electrical activity — think of it as adding more dimensions to the rhythm — and provides a more indepth picture of the heartbeat.

Can Amazfit Bip U measure blood pressure?

A: No it doesn't and the Blood Oxygen measurement if difficult to get a reading as you are required to place your arm horizontal on a flat surfae and hold very still to get the measurement.

Can I answer calls on my Amazfit watch?

The Amazfit GTS 2 can receive and answer calls on the watch but you can dial out on the watch , you can receive text message notifications but you can't reply to the text messages on the watch .

Does Amazfit Bip U have SpO2?

Given the times we are in, the Amazfit Bip U also offers blood oxygen level measurements. This appears under the SpO2 head.

Can PPG be used for HRV analysis?

Photoplethysmography (PPG) sensors integrated in wearable devices such as smart watches and phones are widely used to measure heart activities. HRV requires accurate estimation of time interval between consecutive peaks in the PPG signal.

What is the graph shown in pulse oximeter?

Pulse bar graph is a visual representation of your pulse beat. It is a useful feature used to determine the reliability of a reading. The height of the pulse bar graph correlates to pulse strength. In general, the height of the pulse bar graph should be at least 30% when a reading is taken.

What is a good heart rate variability?

A good HRV score is relative for each person. HRV is a highly sensitive metric and responds uniquely for everyone. As a rule of thumb, values below 50 ms are classified as unhealthy, 50–100 ms signal compromised health, and above 100 ms are healthy.

Are EKG and ECG the same?

An electrocardiogram records the electrical signals in the heart. It's a common and painless test used to quickly detect heart problems and monitor the heart's health. An electrocardiogram — also called ECG or EKG — is often done in a health care provider's office, a clinic or a hospital room.

Can you estimate blood pressure from ECG?

It has been reported that the pulse transit time (PTT), the interval between the peak of the R-wave in electrocardiogram (ECG) and the fingertip photoplethysmogram (PPG), is related to arterial stiffness, and can be used to estimate the systolic blood pressure (SBP) and diastolic blood pressure (DBP).

How are BP and ECG related?

Blood pressure (BP) and the electrocardiographic (ECG) signal, or electrical signal of the heart, are physical measurements that provide insight into the behavior of the cardiac system. This paper presents a novel methodology, where for the first time the relationship between BP and ECG signal is shown.

How do you know if you have good blood pressure?

Normal blood pressure for most adults is defined as a systolic pressure of less than 120 and a diastolic pressure of less than 80. Elevated blood pressure is defined as a systolic pressure between 120 and 129 with a diastolic pressure of less than 80.

What does PPG signal mean?

Photoplethysmography (PPG) is a simple optical technique used to detect volumetric changes in blood in peripheral circulation. It is a low cost and non-invasive method that makes measurements at the surface of the skin.
