In Search of a Rhythmic Heartbeat with AFib?
Participate in Undiagnosed Atrial Fibrillation Clinical Trials!
Undiagnosed atrial fibrillation (AFib) is a common heart rhythm disorder that significantly impacts heart function and overall health. It occurs when the upper chambers of the heart (atria) beat irregularly and out of sync with the lower chambers, leading to an uneven and often rapid heartbeat. This condition can cause palpitations, fatigue, shortness of breath, dizziness, and an increased risk of stroke.
AFib may develop due to a variety of underlying causes, including high blood pressure, heart disease, thyroid disorders, or other cardiovascular complications. Over time, it can reduce quality of life and place strain on both the body and emotional well-being.
If you or someone you know is living with undiagnosed atrial fibrillation, Revival Research Institute is currently conducting clinical trials to explore potential new treatment options aimed at improving outcomes and overall quality of life.
Is this Clinical Trial the Right Fit for You?
The eligibility criteria to participate in the Undiagnosed Atrial Fibrillation Clinical Trials includes:
- Being at least 18 years or older
- Having been diagnosed with Undiagnosed Atrial Fibrillation
*Additional criteria may apply.
Participation in the Undiagnosed Atrial Fibrillation Clinical Trials is completely free. To learn more or see if you qualify, simply fill out the form below. A member of our research team will reach out to discuss your eligibility and guide you through the next steps.
Undiagnosed Atrial Fibrillation Clinical Trials
Dealing with undiagnosed atrial fibrillation (AFib) can disrupt your daily life, causing irregular heartbeat, palpitations, fatigue, shortness of breath, dizziness, and reduced ability to carry out everyday activities. Beyond the physical symptoms, AFib may also increase the risk of stroke and affect emotional well-being, making proper treatment and support essential.
Revival Research Institute is currently conducting a clinical trial to evaluate the safety and effectiveness of an investigational treatment for individuals diagnosed with undiagnosed atrial fibrillation. The goal of this study is to explore whether the treatment can help restore normal heart rhythm, reduce symptoms, and improve overall quality of life.
The trial is being conducted at multiple research sites across the United States. To participate, individuals will go through a screening process and must be willing to follow all study-related procedures. Eligible participants will be randomly assigned to receive either the investigational treatment or a placebo.
All study-related care, procedures, and medication are provided at no cost. No insurance is required to participate, and eligible participants may also be compensated for their time and travel.
Get Started
What to Expect?
If you’re living with undiagnosed atrial fibrillation (AFib), you may qualify for a clinical trial exploring new investigational treatment options. After submitting the interest form above, a member of our research team will contact you for a brief pre-screening to determine if you meet the initial eligibility criteria.
If you qualify, you will be asked to review and sign an Informed Consent Form (ICF), which outlines all study procedures, potential benefits, and possible risks. Once consent is provided, you will be invited to one of Revival’s sites in Michigan or Texas for a screening visit. During this visit, we’ll go over your medical history, conduct physical exams, and perform lab tests to confirm eligibility. Participants who meet all study requirements may be enrolled in the Undiagnosed Atrial Fibrillation Clinical Trial.
Our team is dedicated to making sure you fully understand your role in the study and what to expect at each step. Feel free to ask questions at any time. Your participation plays an important role in helping us advance future treatment options for this common yet serious heart rhythm disorder.

A Guide to Undiagnosed Atrial Fibrillation

Undiagnosed atrial fibrillation (AFib) is a common heart rhythm disorder that can significantly impact overall health. It occurs when the upper chambers of the heart (atria) beat irregularly and out of sync with the lower chambers (ventricles), leading to an uneven and often rapid heartbeat. This irregular rhythm makes it harder for the heart to pump blood effectively throughout the body.
AFib can cause symptoms such as palpitations, fatigue, shortness of breath, dizziness, and reduced exercise capacity. If left untreated, it may lead to serious complications including stroke, heart failure, and a decreased quality of life.
Undiagnosed Atrial Fibrillation May Be Caused By:
- High blood pressure (hypertension)
- Coronary artery disease or prior heart attack
- Heart valve disease (especially mitral valve problems)
- Heart failure or cardiomyopathy
- Thyroid disorders (overactive thyroid)
- Sleep apnea
Common Symptoms of Undiagnosed Atrial Fibrillation
- Irregular or rapid heartbeat (palpitations)
- Fatigue or weakness
- Shortness of breath
- Dizziness or lightheadedness
- Dizziness
- Chest discomfort or pain

What is undiagnosed atrial fibrillation (AFib) and why is it a problem?
Undiagnosed atrial fibrillation or AFib is an irregular or abnormal heartbeat that begins as short periods of irregular beating, with increased duration, over time. It may be a problem as when the heart is in AFib, it is unable to pump oxygen-rich blood throughout the body leading to complications such as formation of blood clots which eventually leads to stroke, or heart failure.
What is the greatest risk of AFib?
The greatest risk of AFib is stroke as it causes the blood to pool and move slower than usual. This can result in a clot, that eventually may lead to stroke.
Where can I learn more about Undiagnosed Atrial Fibrillation Clinical Trials location?
The AFib Clinical Trials are being carried out in Michigan and Texas. For more information on our sites and their location, please visit our locations. Once our research team reaches out to you, we will guide you and provide you with complete details of the location of the site.
Is AFib a fatal condition?
AFib is not a fatal condition itself, however it may lead to complications such as stroke, and heart failure, both of which can be life-threatening if not treated timely.
Can AFib be prevented?
Managing blood pressure, limiting alcohol and caffeine, exercising, eating a heart-healthy diet, and treating sleep apnea may reduce the risk.
