Palpitations: When to Worry About Heart Rhythm Issues

Palpitations? Arrhythmia?

Hello Dr.
Liu: Over the past week, I have been experiencing occasional pain in my left chest, and I sometimes feel my heartbeat very prominently (it feels strong during normal daily activities).
A few days ago, I had an electrocardiogram (ECG), but the doctor said there were no significant abnormalities.
However, during the auscultation, he heard an abnormal sound and advised me to schedule a 24-hour Holter monitor for next Monday.
In the past few days, when I check my pulse, I notice it isn't very steady.
After physical activity, my pulse quickens, which seems normal, but during regular activities, I feel my pulse fluctuating (for example, after five beats, the interval between the sixth and seventh beats is prolonged).
Additionally, I have another symptom where I feel a sensation of air being expelled from my throat, which triggers a dry cough, not productive.
Could these symptoms indicate arrhythmia or just general palpitations? Do I need further treatment? Thank you for your understanding, and I apologize if my description is a bit disorganized.

Based on your description, it is possible that you have mild arrhythmia, which may manifest as premature contractions (also known as ectopic beats).
This is a condition that can occur in the general population and is usually not a cause for concern.
It is often related to emotional stress, work-related pressure, excessive fatigue, or lack of sleep.
It is advisable to make some adjustments, such as engaging in exercise, relaxation techniques, and improving sleep quality.

When it comes to understanding palpitations and when to worry about heart rhythm issues, it's essential to consider various factors, including the nature of the symptoms, any underlying health conditions, and the results of diagnostic tests. Based on your description, it seems you are experiencing a combination of chest pain, noticeable heartbeats, and irregular pulse sensations, which can understandably cause concern.

Understanding Your Symptoms
1. Palpitations: Palpitations are often described as the sensation of having a fast-beating, fluttering, or pounding heart. They can occur in the absence of any underlying heart disease and are frequently triggered by stress, anxiety, caffeine, or vigorous physical activity. In your case, the fact that your heart rhythm appears to be normal during the electrocardiogram (ECG) is reassuring. However, the presence of an abnormal sound during auscultation may warrant further investigation.

2. Chest Pain: The left-sided chest pain you are experiencing can be attributed to various causes, including musculoskeletal issues, gastrointestinal problems (like acid reflux), or anxiety. Given your history of anxiety and the potential for panic attacks, it's possible that stress and anxiety are contributing to your symptoms. However, it is crucial to rule out any cardiac issues, especially since you mentioned the abnormal sound detected by your physician.

3. Irregular Pulse: The sensation of an irregular pulse, where you feel the heartbeat is not steady, can be concerning. This may indicate an underlying arrhythmia, but it can also be a benign phenomenon, especially if it occurs intermittently and is not associated with other symptoms like dizziness, fainting, or significant shortness of breath.

4. Dry Cough Sensation: The feeling of air being expelled from your throat and the urge to cough could be related to anxiety or a respiratory issue. It is not typically associated with heart rhythm problems but could be a manifestation of anxiety or even gastroesophageal reflux disease (GERD).

When to Worry
While many cases of palpitations are benign, certain red flags indicate the need for further evaluation:
- Persistent Symptoms: If your symptoms persist or worsen, it is essential to seek further medical evaluation.

- Associated Symptoms: Symptoms such as dizziness, fainting, severe chest pain, or shortness of breath should prompt immediate medical attention.

- Family History: If there is a family history of heart disease or sudden cardiac events, this may increase your risk and warrant closer monitoring.

Next Steps
1. 24-Hour Holter Monitor: Since your physician has recommended a 24-hour Holter monitor, this is an excellent step to capture your heart's rhythm over an extended period. This test can help identify any arrhythmias that may not be evident during a standard ECG.

2. Lifestyle Modifications: Consider lifestyle changes that can help manage your symptoms. Reducing caffeine intake, managing stress through relaxation techniques, and ensuring adequate sleep can be beneficial.

3. Follow-Up: After your Holter monitor results are available, follow up with your healthcare provider to discuss the findings and any necessary treatment options. If the results are normal but your symptoms persist, further evaluation by a cardiologist may be warranted.

4. Mental Health Support: Given the potential role of anxiety in your symptoms, consider discussing your mental health with a professional. Cognitive-behavioral therapy (CBT) and other therapeutic approaches can be effective in managing anxiety and its physical manifestations.

Conclusion
In summary, while your symptoms may be concerning, they are not uncommon and can often be managed effectively. The key is to continue monitoring your symptoms, follow up with your healthcare provider, and address any underlying anxiety or stress. Remember, it is always better to err on the side of caution when it comes to heart health, so do not hesitate to seek further evaluation if needed.
