Heart rate issues

Hello Doctor: I would like to ask, sometimes I feel my heart racing and it makes me uncomfortable, and sometimes I even feel it at night while sleeping.
Usually, when this happens, I have to take several deep breaths to feel better.
Recently, I visited a nearby cardiovascular clinic for an examination, where they performed an electrocardiogram and measured my blood pressure, both of which were within normal ranges.
Is this phenomenon considered palpitations, or could there be another reason? If so, what should I pay attention to?

There are many situations that can cause palpitations, commonly including lifestyle stress, tobacco and alcohol use, and even changes in temperature.
Certain medical conditions are also associated with palpitations, such as arrhythmias, mitral valve prolapse, or hyperthyroidism, among others.
It is advisable to start with lifestyle adjustments, such as managing and alleviating stress, maintaining a regular sleep schedule, incorporating exercise, and avoiding stimulants like tobacco, alcohol, and caffeine.
For symptom control, medications can be helpful for many individuals.

More Info

Experiencing a rapid heartbeat, often referred to as palpitations, can be concerning and may lead to anxiety about potential underlying heart problems. It's important to understand that while palpitations can be associated with heart conditions, they can also arise from a variety of non-cardiac causes.

Causes of Rapid Heartbeat
1. Physiological Factors: Rapid heartbeats can occur due to physical exertion, stress, anxiety, or panic attacks. These situations activate the body's "fight or flight" response, leading to an increase in heart rate.

2. Medical Conditions: Conditions such as hyperthyroidism, anemia, or electrolyte imbalances can also cause palpitations. Additionally, heart conditions like atrial fibrillation, supraventricular tachycardia, or other arrhythmias may lead to a rapid heartbeat.

3. Stimulants: Caffeine, nicotine, and certain medications can stimulate the heart and lead to palpitations. Alcohol consumption can also contribute to irregular heart rhythms.

4. Hormonal Changes: Hormonal fluctuations, such as those occurring during menstruation, pregnancy, or menopause, can also affect heart rate.

5. Gastrointestinal Issues: Sometimes, gastrointestinal problems like acid reflux can cause sensations that feel like heart palpitations.

Symptoms to Watch For
While a rapid heartbeat can be benign, certain accompanying symptoms may indicate a need for medical evaluation. These include:
- Chest pain or discomfort
- Shortness of breath
- Dizziness or lightheadedness
- Fainting or near-fainting episodes
- Severe anxiety or panic
If you experience any of these symptoms alongside your rapid heartbeat, it is crucial to seek medical attention promptly.

When to Seek Help
Given that you have already undergone an electrocardiogram (ECG) and blood pressure evaluation, and both were normal, it may suggest that your rapid heartbeat is not due to a serious heart condition. However, if your symptoms persist or worsen, or if you develop new symptoms, it is advisable to consult with a healthcare provider. They may recommend further testing, such as:
- Holter Monitor: This device records your heart's activity over 24-48 hours to capture any irregularities that may not appear during a standard ECG.

- Echocardiogram: This ultrasound of the heart can help assess its structure and function.

- Blood Tests: To check for thyroid function, electrolyte levels, and other potential causes.

Management and Lifestyle Modifications
1. Stress Management: Techniques such as deep breathing exercises, meditation, and yoga can help reduce anxiety and stress, which may alleviate palpitations.

2. Avoid Stimulants: Reducing or eliminating caffeine, nicotine, and alcohol can help manage your symptoms.

3. Regular Exercise: Engaging in regular physical activity can improve overall cardiovascular health and reduce anxiety.

4. Healthy Diet: Eating a balanced diet rich in fruits, vegetables, whole grains, and lean proteins can support heart health.

5. Stay Hydrated: Dehydration can lead to electrolyte imbalances, which may trigger palpitations.

Conclusion
In summary, while rapid heartbeat can be alarming, it is often benign, especially if accompanied by normal heart function tests. However, it is essential to remain vigilant and consult a healthcare provider if symptoms persist or worsen. By understanding the potential causes and implementing lifestyle changes, you can better manage your symptoms and maintain your overall health.
