Palpitations / Sudden increase in heart rate?


Hello, doctor.
I have mitral valve prolapse and no thyroid issues, but recently I've been experiencing palpitations after eating even a small amount of food.
My heart rate can reach around 100 beats per minute, and when I feel uncomfortable, it tends to increase even more.
I also experience tightness in my shoulders and back, weakness in my legs, and sometimes sudden abdominal bloating that makes it hard to breathe.
Occasionally, my heart beats faster than usual.
I underwent a 24-hour Holter monitor test, and the doctor mentioned that I had over 100 instances of increased heart rate in a day, but everything else was normal.
Currently, I am not taking any medication, but I can easily reach a heart rate of 130, and once it even hit 160.
I feel weak in my legs and can’t stand, but after resting for an hour, I gradually feel better.
This happens about twice a day.
I have considered going to the emergency room for advice since I will be traveling to Europe soon.
I am worried that my heart rate might become uncontrollable and lead to fainting or shock.
What if I experience a rapid heart rate in the cold while abroad? My cardiologist prescribed Xanax 0.25 mg for me to take before flying.
Should I take it one hour before the flight? Are there any side effects? Will the effects wear off suddenly and cause my heart rate to increase even more? Or can I manage without medication? I plan to visit ice caves and go hiking in Europe; is that safe for me? Since my heart rate can easily increase or have extra beats, is there a risk that if this continues, it could lead to sudden cardiac arrest one day?

Hello, after undergoing a 24-hour Holter monitor, it was found that there were over 100 instances of premature beats in one day, but everything else was normal.
This is actually very good and does not mean that you will suddenly experience a rapid heartbeat leading to fainting or shock! Even in cold environments abroad, a sudden increase in heart rate does not necessarily lead to death.
The effects of medication can vary, but a significantly faster heart rate does not typically lead to sudden cardiac arrest.
Sudden increases in heart rate can occur occasionally, but this is usually benign arrhythmia and poses no danger to life.
There is no need to worry; if you are concerned, you can ask your physician to prescribe medication to help regulate your heart rhythm.
Rest assured, Changhua Hospital cares about your well-being.

Managing heart palpitations, especially for individuals with mitral valve prolapse (MVP), can be a concern, particularly when traveling. It's important to understand the nature of your condition and how to manage it effectively, especially in unfamiliar environments.

Mitral valve prolapse is a common heart valve disorder where the valve does not close properly, which can lead to palpitations, anxiety, and sometimes chest discomfort. Your experience of palpitations after eating, along with feelings of tightness in your shoulders and legs, could be related to anxiety or the body's response to stress. It’s not uncommon for individuals with MVP to experience heightened sensitivity to stressors, which can trigger palpitations.

Here are some tips to manage your heart palpitations while traveling:
1. Medication Management: You mentioned that your doctor prescribed a small dose of Xanax (0.25 mg) to take before your flight. This medication can help alleviate anxiety, which may reduce the frequency and intensity of your palpitations. It’s generally recommended to take it about an hour before your flight. However, be aware of potential side effects such as drowsiness or dizziness. It's crucial to discuss any concerns about side effects with your doctor, especially regarding how you might feel during your travels.

2. Stay Hydrated and Eat Light: When traveling, especially by air, dehydration can exacerbate palpitations. Drink plenty of water and try to eat smaller, more frequent meals rather than large ones. Avoid caffeine and high-sugar foods, as these can trigger palpitations.

3. Practice Relaxation Techniques: Techniques such as deep breathing, meditation, or progressive muscle relaxation can help manage anxiety and reduce palpitations. Consider practicing these techniques before and during your trip.

4. Know Your Limits: If you are planning to engage in activities like exploring ice caves or hiking in the mountains, listen to your body. If you start to feel unwell or experience significant palpitations, it’s okay to take a break or modify your plans.
5. Monitor Your Symptoms: Keep track of your palpitations, noting when they occur and any associated symptoms. This information can be helpful for your healthcare provider if you need to follow up after your trip.

6. Emergency Plan: Before traveling, ensure you have a plan in case of severe palpitations or other symptoms. Know where the nearest medical facilities are located at your destination, and consider carrying a list of your medications and medical history.

7. Consult Your Doctor: Given your concerns about palpitations and the potential for them to worsen, it’s advisable to have a thorough discussion with your cardiologist before your trip. They may recommend additional monitoring or adjustments to your medication regimen.

8. Avoid Triggers: Identify and avoid known triggers for your palpitations, which may include stress, certain foods, or strenuous activities.
9. Stay Calm: Anxiety about your heart condition can sometimes exacerbate symptoms. Remind yourself that MVP is often manageable and that many people live full, active lives with the condition.

In conclusion, while it’s understandable to feel anxious about your heart condition while traveling, with proper management and precautions, you can enjoy your trip. Always prioritize your health and well-being, and don’t hesitate to seek medical attention if you feel that your symptoms are becoming unmanageable. Safe travels!
