Heart Palpitations During Exercise: When to Seek Help - Cardiology

More Info

---

Heart palpitations during exercise can be concerning, especially for individuals with a history of anxiety and mild heart conditions such as mitral valve prolapse. It’s important to understand that while palpitations can be benign, they can also indicate underlying issues that may require further evaluation.
From your description, it seems you have undergone a comprehensive evaluation, including a 24-hour Holter monitor, echocardiogram, and blood tests, all of which have shown no significant abnormalities aside from mild mitral valve prolapse. This condition is generally considered benign, especially when there are no accompanying symptoms such as chest pain, severe shortness of breath, or syncope (fainting).
The sensation of your heart "skipping a beat" or feeling like it "sinks" momentarily during exercise can be attributed to several factors, including anxiety, dehydration, electrolyte imbalances, or even the effects of increased physical exertion on your heart. Given your history of anxiety and autonomic nervous system dysregulation, it’s not uncommon for individuals in your situation to experience heightened awareness of their heart rate and rhythm, which can amplify feelings of anxiety during exercise.


When to Seek Help
You should consider seeking further medical advice if:
1. You experience any new or worsening symptoms: This includes chest pain, severe shortness of breath, dizziness, or fainting spells during or after exercise.

2. The palpitations become more frequent or severe: If you notice an increase in the frequency of these episodes or if they last longer than usual.

3. You feel a significant change in your overall health: Any new symptoms that concern you should be discussed with your healthcare provider.


Continuing Exercise
Exercise is generally beneficial for both physical and mental health, especially for anxiety management. However, it’s crucial to listen to your body. If you feel comfortable and your symptoms are manageable, you can continue exercising, but consider the following:
- Start Slow: Gradually increase your exercise intensity and duration. This can help your body adapt and may reduce the occurrence of palpitations.

- Stay Hydrated: Dehydration can exacerbate palpitations, so ensure you are drinking enough fluids before, during, and after exercise.

- Monitor Your Heart Rate: While it’s good to be aware of your heart rate, try not to fixate on it excessively, as this can increase anxiety. Consider using a heart rate monitor that can provide you with data without needing to manually check your pulse frequently.

- Practice Relaxation Techniques: Incorporating mindfulness, deep breathing, or yoga can help manage anxiety levels, which may, in turn, reduce the frequency of palpitations.


Conclusion
In summary, while your palpitations during exercise can be alarming, they are likely related to your anxiety and the benign nature of your heart condition. However, it’s always wise to consult with your healthcare provider if you have concerns or if your symptoms change. They may recommend additional monitoring or a tailored exercise program that considers your specific health needs. Remember, maintaining a healthy lifestyle through regular exercise, a balanced diet, and stress management techniques can significantly improve your overall well-being.
