Rapid Heartbeat: Symptoms, Causes, and When to Seek Help - Cardiology

More Info

---

It sounds like you are experiencing a range of concerning symptoms, including a rapid heartbeat, shortness of breath, dizziness, headaches, and chest tightness. Your resting heart rate of around 90 beats per minute is on the higher end of the normal range, which typically lies between 60 and 100 beats per minute. However, a heart rate above 100 beats per minute is generally considered tachycardia, especially if it occurs at rest or without significant exertion.

The symptoms you describe—such as rapid heartbeat, shortness of breath, and chest discomfort—can be indicative of several underlying issues. These may include anxiety or panic attacks, which are common causes of rapid heart rate and can also lead to feelings of chest tightness and dizziness. Other potential causes could be related to cardiovascular issues, respiratory problems, or even gastrointestinal disturbances, such as acid reflux, which can mimic heart-related symptoms.

Given that you mentioned experiencing these symptoms during physical activity, it is important to consider your overall fitness level and any recent changes in your activity. While exercise is generally beneficial for cardiovascular health, if you are not accustomed to regular physical activity, it is possible that your body is reacting to the increased exertion. However, the fact that you experience significant discomfort, such as chest pain and breathlessness, during relatively mild exercise warrants further investigation.

Your blood pressure readings of 111/78 are within the normal range, which is reassuring. However, the combination of your symptoms—especially the chest pain and rapid heartbeat—should not be ignored. It is crucial to differentiate between benign causes and those that may require medical attention.

In terms of when to seek help, you should consider visiting a healthcare provider if:
1. Your symptoms persist or worsen.

2. You experience severe chest pain, especially if it radiates to your arm, jaw, or back.

3. You have episodes of fainting or severe dizziness.

4. You notice any swelling in your legs or feet, which could indicate heart issues.

5. Your heart rate remains elevated even at rest.

For your next steps, I recommend scheduling an appointment with a cardiologist, as they specialize in heart-related issues. They may perform a thorough evaluation, including an electrocardiogram (ECG), echocardiogram, and possibly a stress test to assess how your heart responds to exercise. These tests can help determine if there are any underlying cardiac conditions contributing to your symptoms.

In the meantime, consider keeping a diary of your symptoms, noting when they occur, their duration, and any potential triggers. This information can be invaluable for your healthcare provider in diagnosing your condition.

Lastly, while it is essential to seek medical advice, also consider lifestyle modifications that can help manage your symptoms. These include:
- Regular, moderate exercise tailored to your fitness level.

- Stress management techniques such as mindfulness, yoga, or deep-breathing exercises.

- Avoiding stimulants like caffeine and nicotine, which can exacerbate heart rate issues.

- Ensuring you stay hydrated and maintain a balanced diet.

In summary, while your symptoms may stem from anxiety or other benign causes, it is crucial to consult with a healthcare professional to rule out any serious conditions. Your health is paramount, and addressing these symptoms early can lead to better outcomes.
