Cardiac Arrhythmia Telemetry; Conventional vs HeartWatch
Heart rhythm problems, such as atrial fibrillation (AF) or very slow heartbeats, are common and can significantly affect daily life. Currently available monitoring devices are often worn for short periods or require surgery. This study is testing a new, easy-to-wear device called HeartWatch. You wear it on your upper arm, it connects to a smartphone app, and allows you to note down your symptoms as they happen. We want to see how accurate HeartWatch is at picking up heart rhythm issues compared to the standard Holter monitor. We're also checking how reliable its automatic detection features are, if there are any side effects with either device, and which one patients prefer to wear. This will help us understand if HeartWatch can be a better way to monitor your heart over a longer period.
At a glance
What is this study about?
Many people experience problems with their heartbeat, which doctors call heart rhythm disorders or arrhythmias. These can include a fast, irregular heartbeat like atrial fibrillation (AF), or sometimes a heartbeat that is too slow. These conditions can make you feel unwell and greatly impact your daily life.
Catching these problems isn't always easy because they might not happen all the time. Current methods for checking your heart rhythm only look for a short period or involve having a device implanted into your body. This study is testing a new device called the HeartWatch. It's designed to be worn on your upper arm for a longer time, helping to catch those tricky heart rhythm changes. It also links to your smartphone, so you can easily record how you're feeling when your heart rhythm acts up.
The main goal of this study is to compare the HeartWatch with a standard heart monitor, called a Holter monitor. We want to see how accurately they both detect heart rhythm problems. We’re also looking at how reliable their automatic detection systems are, and which device patients find more comfortable and easier to use. This research is important because it could lead to better ways to monitor and understand heart rhythm conditions for many people.
Key takeaways
- This study compares a new device (HeartWatch) with standard heart monitors.
- It aims to find better ways to detect heart rhythm problems like Atrial Fibrillation.
- HeartWatch is worn on the upper arm and links to a smartphone app.
- Your feedback on comfort and preference is important.
- Taking part helps improve future heart monitoring for others.
Who may be eligible?
To join this study, you need to be at least 22 years old and have a doctor who thinks you need a standard Holter monitor test. You must also be able to wear the HeartWatch on your left upper arm for the whole study period. Your left upper arm measurement needs to be between 22 cm and 45 cm. You should also be able to follow the study instructions and provide your written agreement to take part.
There are some reasons why you wouldn't be able to join. For example, if you have a known allergy to any part of the HeartWatch or the Holter monitor. You also can't take part if you have a pacemaker or defibrillator implanted in your body, or if you have a medical condition that would make wearing the HeartWatch on your left arm difficult or unsafe, such as a severe skin condition or a history of blood clots in that arm. People with a rare condition where their heart is on the right side of their chest (dextrocardia) also cannot participate.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you at least 22 years old?
- Has your doctor suggested you need a Holter monitor test?
- Can you wear a device on your left upper arm?
- Do you have an implanted pacemaker or defibrillator? (If yes, you may not be suitable)
- Is your left upper arm measurement between 22 cm and 45 cm?
- Do you have any severe skin allergies to medical adhesives?
What does participation involve?
If you decide to take part, you'll be asked to wear two heart monitoring devices at the same time: a standard Holter monitor and the new HeartWatch. The HeartWatch fits on your upper arm and connects to a smartphone app, allowing you to record any symptoms you feel. We will compare the information collected by both devices to see how accurate the HeartWatch is. We'll also ask you about your experience and preference for each device. The exact duration of wearing the devices and any follow-up will be explained in detail when you consider joining the study.

Common questions
What is a heart rhythm problem?
It's when your heart beats too fast, too slow, or in an irregular way, causing symptoms like palpitations or dizziness.
What is a Holter monitor?
It's a small, portable device you wear to record your heart's electrical activity over 24-48 hours, usually with sticky patches on your chest.
How is HeartWatch different?
HeartWatch is worn on your upper arm, potentially for longer periods, and connects to a smartphone app so you can record your symptoms easily.
Will I get to see my heart information?
The information collected will be used for the study. Your doctor will discuss all relevant findings with you as part of your usual care.
Is the HeartWatch available to buy now?
No, it is an investigational device being tested in this study and is not currently available for general use.
