Heart Palpitations: Panic Attacks or Cardiac Issues? - Cardiology

More Info

---

Heart palpitations can be a source of significant concern for many individuals, especially when they are accompanied by anxiety or panic attacks. In your case, the recent echocardiogram indicated mild mitral regurgitation (MR) and trivial tricuspid regurgitation (TR), but otherwise normal results. This suggests that your heart's structure is largely intact, and the mild regurgitation is not uncommon and often does not lead to significant symptoms or complications.

Palpitations are often described as a sensation of the heart racing, fluttering, or pounding, and they can occur for various reasons. In your situation, the timing of the palpitations—occurring primarily at night before sleep—could indeed be related to anxiety or panic attacks. Panic attacks can trigger a fight-or-flight response, leading to an increase in heart rate and the sensation of palpitations. This is a physiological response to stress, where the body releases adrenaline, causing the heart to beat faster.

It's important to differentiate between palpitations caused by anxiety and those that may indicate a cardiac issue. Given that your echocardiogram was normal aside from mild MR and TR, and considering your history of panic disorder, it is likely that your palpitations are more related to anxiety rather than a significant cardiac problem. However, it is crucial to monitor your symptoms and discuss them with your healthcare provider, especially if they become more frequent or severe.

Here are some additional considerations and recommendations:
1. Monitor Symptoms: Keep a diary of your palpitations, noting when they occur, their duration, and any associated symptoms (like shortness of breath, dizziness, or chest pain). This information can be helpful for your healthcare provider.

2. Stress Management: Since anxiety can exacerbate palpitations, consider incorporating stress-reduction techniques into your daily routine. Practices such as mindfulness, meditation, yoga, or deep-breathing exercises can help manage anxiety levels.

3. Lifestyle Modifications: Regular physical activity, a balanced diet, adequate hydration, and sufficient sleep can positively impact your overall well-being and may help reduce anxiety and palpitations.

4. Avoid Stimulants: Caffeine, nicotine, and certain medications can increase heart rate and may trigger palpitations. Reducing or eliminating these substances may help.

5. Follow-Up with Your Doctor: Since you have a history of panic disorder, it may be beneficial to discuss your symptoms with a mental health professional. They can provide strategies to manage anxiety and may recommend therapy or medication if necessary.

6. Cardiac Evaluation: If your palpitations persist or worsen, your doctor may recommend further evaluation, such as a Holter monitor or an event recorder, to assess your heart rhythm over a more extended period.

In summary, while your symptoms of palpitations are likely related to anxiety, it is essential to remain vigilant and maintain open communication with your healthcare provider. They can help you navigate your symptoms and determine if any further investigation or treatment is needed. Remember, managing anxiety effectively can significantly improve your quality of life and reduce the frequency of palpitations.
