• Individuals can monitor their heart rhythm at home using a manual pulse check and KardiaMobile devices, while smartwatches and fitness trackers with ECG technology provide an innovative method for detecting AFib.

• Despite the availability of at-home monitoring methods, professional diagnosis of abnormal heart rhythms often requires a medical-grade ECG in a healthcare setting; lifestyle factors such as diet and stress directly impact heart rhythm health and should be managed appropriately.

Understanding AFib and Its Symptoms

Atrial fibrillation, or AFib as it is commonly known, is the most prevalent form of heart arrhythmia. This condition is characterized by irregular contractions of the upper heart chambers, which can affect blood vessels and blood flow, and significantly increases risk for stroke. Symptoms of AFib may encompass a sensation of skipped or added heartbeats, or a ‘fluttering’ sensation. In some cases, individuals may have more subtle symptoms such as fatigue or shortness of breath, and some patients may not experience any noticeable symptoms.

AFib has the potential to lead to serious complications, such as:

• blood clots

• stroke

• heart failure

In fact, AFib is a significant health concern, with over 450,000 hospitalizations attributed to it as the primary diagnosis annually in the United States, leading to approximately 158,000 deaths each year. It is projected that by 2030, the number of individuals in the U.S. affected by AFib will reach 12.1 million.

So, suspecting AFib or experiencing irregular heartbeats, warrants scheduling a doctor’s appointment, as these symptoms could potentially lead to sudden cardiac arrest.

At-Home Monitoring Techniques for Detecting AFib

At-home monitoring techniques empower individuals to proactively detect early signs of AFib, contributing to their heart health. Several options are available for at home monitoring, including manual pulse checks, KardiaMobile devices, and smart watches.

Manual Pulse Check

A manual pulse check is a simple to monitor your heart rhythm. You can locate your pulse on your wrist or neck, and then monitor it for approximately 30 seconds. If your pulse feels regular or irregular, it could indicate the presence of AFib. A normal pulse is characterized by its steady and regular rhythm at rest, whereas an irregular pulse may feel uneven or erratic, often described as ‘jumping about’.

Be aware that AFib may cause a pulse rate exceeding 100 beats per minute, exceeding the typical adult resting heart rate of 60 to 100 beats per minute. This irregular heart rhythm can occasionally lead to symptoms such as palpitations, shortness of breath, or chest pain.

With that said, a manual pulse check is the least accurate method for checking for AFib, compared to the other options listed below.

When to Use a Medical-Grade ECG or Cardiac Monitor

While home monitoring techniques offer valuable heart health insights, certain instances necessitate a medical-grade heart monitor. To diagnose an abnormal heart rhythm, a clinical or medical-grade electrocardiogram (ECG or EKG) is typically used. This test helps healthcare providers understand the nature of the heart’s electrical activity. To evaluate the heart rate and rhythm, sensors or electrodes are attached to the chest and various limb. ECGs are commonly performed in medical facilities such as doctor’s offices, clinics, or hospitals.

A heart monitor patch is an adhesive placed on the chest area to monitor and record heart activity. These patches are an integral part of the standard ECG procedure in medical settings. In some cases, a holter monitor or a cardiac event monitor may be used for long-term monitoring of infrequent symptoms in heart patients, with prolonged monitoring for several days or weeks as needed.

Recognizing False Positives and Negatives

As with any technology, at-home monitoring methods are not perfect and can sometimes yield false positives or negatives. Factors like noise, other arrhythmias, frequent ectopy, and oversensing can lead to incorrect positive results. Meanwhile, false negatives occur with a prevalence of approximately 33.3%, due to factors like misinterpretation of ECGs, patient characteristics, and the presence of other heart rhythm abnormalities.

Nevertheless, technological advancements, including advanced processing of photoplethysmographic (PPG) and accelerometer recordings, have diminished the effect of motion artifacts on AFib detection. Despite the potential for false positives and negatives, consulting with healthcare professionals is essential to ensure an accurate diagnosis of AFib.

Lifestyle Factors That Influence Heart Rhythm

Your lifestyle significantly influences your heart’s rhythm health. Factors such as diet and stress can significantly influence your heart rhythm, making it crucial to maintain a balanced diet and manage stress effectively.

The Role of a Healthy Diet

A healthy diet is one of the key factors in maintaining a healthy heart rhythm. Diets that are rich in:

• ultra-processed foods

• added sugar

• caffeine

• alcohol

• saturated fats

• high sodium foods

have the potential to contribute to heart rhythm disorders like AFib. On the other hand, consuming foods rich in omega-3 fatty acids, like fatty fish, can reduce the likelihood of irregular heartbeat.

It’s also important to monitor your sodium and cholesterol intake. The American Heart Association suggests that individuals with AFib should limit their daily sodium intake to no more than 2,300 milligrams, with an ideal limit of 1,500 mg to promote a healthy heart rhythm. Furthermore, diets high in saturated and trans fats, commonly found in high cholesterol foods, may elevate the risk of AFib and heart rhythm irregularities.

Importance of Managing Stress

Stress is another significant factor that can affect your heart rhythm. Chronic stress and an anxious state can promote AFib through various mechanisms that act at different levels to trigger and modulate heart rhythm. This makes stress management a crucial part of AFib management.

Stress management techniques that can help in decreasing AF episodes and enhancing the overall quality of life for individuals with AFib include:

• Yoga

• Regular exercise

• Maintaining a healthy diet

• Ensuring adequate sleep

• Practicing relaxation techniques

• Mindfulness and meditation

These techniques have been shown to mitigate stress and negative emotions, potentially leading to a decrease in the frequency of AF episodes and an improvement in the overall quality of life for individuals with AFib.

Documenting Your Findings for Your Doctor

Home heart rhythm monitoring is just one part of the process. The other part is accurately recording your findings and communicating them to your healthcare provider. Using an ECG device like KardiaMobile can help you identify dysrhythmias, including AFib.

Alongside ECG recordings, manually checking your pulse and noting any symptoms experienced at the time can assist in a proper diagnosis. Documenting AFib symptoms should include palpitations, dyspnea (shortness of breath), chest pain, and any pulse or jugular venous pulsation irregularities.

Risk Factors and Prevention Strategies

Specific risk factors can elevate your chances of developing AFib. Some of these risk factors include:

• Advancing age

• High blood pressure

• Individuals of European descent (more susceptible compared to African-Americans)

• Obesity

• Hypertension

• Diabetes mellitus

• Physical inactivity

These factors all contribute to the likelihood of developing atrial fibrillation.

AFib prevention entails managing these common risk factors. This includes:

• maintaining a healthy weight

• managing high blood pressure

• controlling cholesterol levels

• reducing alcohol intake

• quitting smoking

• maintaining a heart-healthy diet

Regular exercise and stress management techniques are also beneficial in managing and preventing AFib.

Summary

In conclusion, monitoring your heart rhythm is an essential aspect of heart health, particularly in detecting and managing AFib. While at-home monitoring methods like manual pulse checks, KardiaMobile devices, and wearable technology offer convenient and effective ways to track heart rhythm, they should not replace professional medical advice. Alongside these methods, maintaining a healthy lifestyle through balanced diet and stress management plays a critical role in managing and preventing AFib.
