Why Do I Need A Fetal Monitor
A fetal heart monitor is used in nearly every pregnancy to assess the fetal well-being and identify any changes that might be associated with problems during pregnancy or labor. Monitoring the fetal heart rate is especially crucial for high-risk pregnancy conditions such as problems with fetal growth, high blood pressure, and diabetes. Some situations that might affect the heart rate are: uterine contractions, medicates, and pushing during labor.
Best Fitness Tracker For Heart Rate: Fitbit Charge 4
Price when reviewed: £129.99
The Fitbit Charge 4 is the latest iteration of the now Google-owned company’s flagship tracker and it’s packing in the same HR setup as the Charge 3. So expect a similar performance. Like any wrist-based HR monitor, it can struggle at high intensity, but it will still be good enough for workouts in the gym and on the road if you’re not too worried about pinpoint accuracy.
It’s once again relying on Fibit’s own PurePulse technology to deliver features like real-time heart rate bpm readings while working out and the ability to train in heart rate zones. Fitbit has added some useful heart rate-related features like Active Zone Minutes, which now rewards you for hitting certain heart rate zones. You will also get buzzed when you hit a new heart rate zone during exercise.
Much like the Apple Watch, it’s not just about using heart rate for exercise here. The Charge 3 also monitors heart rate continuously to assess your current state of fitness through resting heart rate readings.
It also uses that sensor to unlock mindfulness features like stress tracking through guided breathing exercises. The heart rate sensor is also put to use during sleep monitoring to produce additional metrics to help analyse the quality of your time in the land of nod.

Different Models Of Heart Rate Monitors
A heart rate monitor is a more scientific way to know how well you are doing, and it can help you keep track of your progress. While there are more devices hitting the market, including rings and bicep straps, there have been two predominant versions of heart rate monitors over the past decade: fitness trackers and chest strap monitors.
Fitness trackers have become quite popular over the last decade as theyre an easy way for people to track certain fitness goals like steps taken, miles run and even more detailed data like calories burned and, yes, your heart rate.
And over the years, Travers notes, technology with fitness trackers has evolved greatly, to the point where accuracy issues of the past have largely been ironed out. And as that tech has gotten better, prices of these devices have come way down, helping their popularity skyrocket.
If you think about 8-to-10 years ago, the only people who were wearing anything like this were serious runners and they were large, somewhat unwieldy devices, Travers says. Now, if you look around, everyones wearing a fitness tracker, whether its an Apple Watch, a Garmin, a Fitbit or something else.
Its letting you know where youre cardiovascular system is at, health-wise, he adds. The lower your resting heart rate is, the less work you heart was to do its normal daily function, which is key. The less stress on our heart to do that, the better off we are.

Starting Off With The Sensors
Simply speaking, fitness trackers measure motion: most of today’s wearables come with a 3-axis accelerometer to track movement in every direction, and some come with a gyroscope too to measure orientation and rotation.
The data collected is then converted into steps and activity and from their into calories and sleep quality, though there is some guesswork involved along the way.
Then there’s the altimeter that can measure your altitude, handy for working out the heigh of the mountains you’ve climbed or the number of flights of stairs you’ve managed to get up and down during the day. All of this information is collected and crunched to create an overall reading, and the more sensors your tracker has, the more accurate its data.
These sensors measure the acceleration, frequency, duration, intensity and patterns of your movementtaken together that’s a good bunch of data and it can help a tracker work out if you’re walking down the road or just waving at someone you know. Have a dive into the specs list of a particular tracker to see what sensors are included to collect data about you.
What Is A Fetal Heart Monitor
Monitoring your fetus during labor and the tail end of your pregnancy is common practice. A fetal heart monitor is used to check the rate, rhythm, and accelerations or decelerations of the fetal heartbeat. The average heartbeat for a fetus is between 110 and 160 beats per minute and may change due to the conditions in the uterus. If the fetal monitor detects there is an abnormal heart rate, that could mean the fetus is not getting enough oxygen or can be indicative of other problems. Sometimes the OB-GYN or your healthcare professional will say that cesarean delivery is needed. It is important to remember that an abnormal heart rate does not always mean that the fetus is in danger.
When Electronic Fetal Monitoring is used, two main components are monitored. The first is the heart rate and the second is the contractions of the uterus. If you have been in labor then you might remember a nurse attaching two belts, each with a circle sensor on them. Both of these sensors are linked to a fetal monitoring device such as the Philips Avalon FM50.; The Avalon FM50 is a sophisticated fetal heart monitor that also has the option to non-invasively monitor maternal vital signs as well as the vitals of the fetus.

The Best Heart Rate Monitors For 2021
Whether you use an arm band or chest strap, smarten up your exercise and training routine by adding ones of the best heart rate monitors we’ve tested.
- Supports ANT+, Bluetooth, and 5 kHz transmission
- Easy to use
- App charges for common features.
- GymLink connection occasionally lags.
Types Of Heart Rate Monitors
Heart rate monitors generally come in two types either a wireless chest strap that sends data to a monitor worn on the wrist, or pulse monitor worn on the wrist that requires you to put your finger on a certain spot to take your pulse.
Both provide real-time input on how hard and how efficiently you are exercising. Heart rate monitors are typically used for cardiovascular exercise, such as walking, running, hiking, climbing and skiing.
The sports-watch models that connect to a chest strap allow for continuous tracking of your heart rate by sending the information to a monitor worn on the wrist. Some advanced models are synchronized with foot pods, which are monitors that are attached to your shoe, typically through the shoelace. This helps to track how far you have gone and how fast you have run to provide a more complete picture of your workout. This also provides the ability to compare performance over time. Some also are connected to GPS to allow for mapping of courses, saving favorite routes and comparing performance.
Higher-end models also have special coding to cut down on interference with other devices, which can happen in a gym setting or a race where a lot of people are wearing heart monitors.
Basic personal heart rate monitors generally display the time of your workout and give you continuous, average, high and low heart rate data and typically provide up to three target heart rates.

What Are The Different Types Of Heart Monitors
The two basic types of monitors are holter monitors and event monitors. Holter monitors can be worn for 24-48 hours, or even extended periods of time. They provide continuous monitoring of a persons electrical heart activity . Event monitors only record activity when triggered by the patient when symptoms occur.

How Do Heart Monitors Work
;Electrodes are placed on the skin, and transmit ECG information to a storage device. Wires typically transmit this, however newer monitors can now work via wireless technology. The information is either stored directly onto a hard drive, and downloaded in the doctors office for interpretation, or transmitted wirelessly to a cloud. The advantage of wireless cloud based technology, is patients can be alerted in real time of any dangerous rhythm abnormalities.
The Value Of Fitness Trackers
Wrist-wornmonitors;are fine for recreational use, Dr. Gillinov says. But theyprobably wont be replacing EKGs in the medical setting any time soon.
Heartpatients who want to make sure theyre staying within safe, physician-recommendedheart rate thresholds during rehabilitation and exercise would be better offusing a chest-worn monitor for the most precise information, Dr. Gillinov says.
Thewrist-worn;fitness devices that include;heart rate monitors areincredibly popular, but if you really want to know your heart rate, wear thechest strap heart monitor because that senses electricity, he says.
Ifyou do still want to use a fitness tracker, Dr. Gillinov advises taking severalmeasurements to get the most accurate reading.
Dontmake too much of a single reading, or even two readings, he says.Do several readings because you cant count on these devices to beaccurate every time.

Are Consumer Heart Rate Monitors Really Accurate
There are many devices on the market today that claim to be able to track your heart rate wherever you go. But how do they compare to what a doctor can measure with an EKG or an old-fashioned pulse reading?
CNET reporter Sharon Profis and Kaiser Permanente cardiologist Dr. Jonathan Zaroff tested five fitness trackers currently on the market. For each test, Profis got three heart rate readings at rest and three after running on a treadmill.
EKG is the gold standard for measuring heart rate using electricity sensors to detect the small pulses of electricity that drive every beat of the heart.
One of the consumer devices tested, the Garmin Vivofit, has a chest strap that connects wirelessly to a wrist strap. According to Zaroff, the Garmin Vivofit “chest straps essentially have an EKG leed over the chest. So it’s the same technology. ” The device was accurate at resting and exercising heart rates. It can be used to measure heart rate while exercising.
The other four devices in the test use optical sensors on the wrist or fingertip and only work standing still. Zaroff observes, “An optical sensor is not near your heart. It’s sensing the flow of blood through your capillaries, one pulse per each heart beat.”
The Withings Pulse O2 has a clip with a removable fingertip pulse monitor. Though it was accurate at resting pulse rates, it couldn’t keep up with Profis’s heart rate when exercising.
How Accurate Are Fitness Tracker Heart Rate Monitors
ByRachael Rettner12 October 2016
Fitness trackers with heart-rate monitors are popular these days, but how accurate are they, really?
A new study put these devices to the test, and the heart-rate monitors’ scores were not stellar some of these wrist-worn heart-rate monitors were more accurate than others, but not one was as accurate as a chest strap monitor, the researchers found.
The results don’t necessarily mean you should ditch your tracker. But if getting an accurate heart-rate measurement is very important to you, then you might want to consider a chest strap monitor, said study author Dr. Marc Gillinov, a cardiac surgeon at Cleveland Clinic.
“If you really must know your heart rate accurately whether that’s for health or training a chest strap with an electrode is best,” Gillinov told Live Science.
People who already have a wrist-worn heart-rate monitor may be aware that readings aren’t always accurate. Gillinov advised users not to panic if they get a heart-rate reading that seems to be way too high or too low. “It may very well be incorrect,” Gillinov said. If this happens, wait a moment and check the reading again, Gillinov said.
Although many studies have tested and confirmed the accuracy of chest-strap heart-rate monitors, there’s been little study of wrist-worn monitors.
In the new study, Gillinov and colleagues tested the wrist-worn heart-rate monitors on four devices: the Apple Watch, the Fitbit Charge HR, the Mio Fuse and the Basis Peak.

What Is A Treadmill Heart Rate Monitor And How Does It Work
If you dont have a smartwatch or fitness tracker, some treadmills will have a pulse rate monitor with automated features that will change speed and incline based on your heart rate. It is a pretty advanced technology that older treadmill models lack.
Technology like this was only available in hospitals before, and they use it for performing stress tests on patients who they suspect heart problems. But because technology is more advanced these days, you can now use it in the comfort of your home.
Heart Rate Monitors: How They Work
ByKim Ann Zimmermann27 December 2013
Heart rate monitors provide immediate feedback on how hard you are working out so that you can make adjustments to get the greatest benefit from your exercise regimen.
The goal is to exercise within your target heart rate zone for maximum impact.; According to the Centers for Disease Control and Prevention, for moderate-intensity physical activity a person’s target heart rate should be 50 percent to 70 percent of his or her maximum heart rate. For example, using the results calculated above for a 50-year-old person, 50 percent and 70 percent levels would be:
- 50 percent level: 170 x 0.50 = 85 beats per minute
- 70 percent level: 170 x 0.70 = 119 bpm
For intense exercise, a 50-year-old person’s target heart rate should be 70 percent to 85 percent of his or her maximum heart rate:
- 70 percent level: 170 x 0.70 = 119 bpm;
- 85 percent level: 170 x 0.85 = 144 bpm
All exercisers can benefit from monitoring their heart rate during activity, enabling them to maintain fat-burning and aerobic target zones based on their goals.

Heart Monitor Data Display
Originally, the signal from the sensors was sent by radio waves to the receiver. Technology has developed to send it through ANT or Bluetooth. This enables devices such as cell phones and other mobile devices and wearable devices to use apps to receive data from the heart rate monitor sensors.
In choosing a heart rate monitor, look for one that has the type of display you can most easily use and understand during your workout. Some have pre-programmed exercise zones based on your age, while others allow you to set your zones to your individual preference.
Best Heart Rate Monitors: Track Fitness And Get Training Insights
ByColin Levitch, Josh Croxton25 August 2021
The best heart rate monitors will help you track your heart rate comfortably and accurately – here’s our pick of the best
The best heart rate monitors are comfortable enough that you forget you’re wearing them, and they aid your training by providing consistent and accurate heart rate data. Until power meters became widespread in cycling, heart rate was the gold standard for measuring training effort and recovery. It’s still an important metric used by athletes – professional or amateur – worldwide. The humble heart rate monitor can provide insight into training effort, exertion, fatigue and more.;
They have been around for decades, with Finnish outfit Polar releasing the first wireless model back in the late 1970s, but technology is improving all the time.;
Now we have lightweight chest straps, optical forearm-based monitors, and small optical wristbands that track your pulse, the latter is now being integrated into fitness trackers and smartwatches at all price points. All of the best smartwatches for cycling use optical heart rate sensors.
Ranging from simple straps that will communicate with your cycling computer to advanced dual-band sensors with onboard memory and even music control, each option can map other metrics like heart rate viability, remember workout data, and even determine cadence.
