Post-Cold Heart Palpitations: Symptoms and Risks

After catching a cold, I experienced a sensation of my heart racing, cold sweats, and dizziness, almost fainting?

Hello, doctor.
I occasionally stay up late or experience chest tightness (along with mild discomfort) after exertion, and I also tend to feel fatigued easily.
Previous ECG tests indicated no issues, but an ultrasound revealed mitral valve prolapse (I can't remember if there was any regurgitation).
Three years ago, I had a severe cold with vomiting and diarrhea.
On that day, while traveling, I forced myself to go outside, and while waiting in line, I suddenly experienced blurred vision, an uncontrollable urge to urinate, profuse sweating, palpitations, and felt like I was about to faint.
My classmates said I looked pale and my lips turned purple, which scared them.
A few days ago, I had another cold with respiratory symptoms, and this time I felt very fatigued, experienced palpitations, and my heartbeat felt very weak (almost undetectable).
I also had a severe episode of cold sweating.
Although I didn't appear as pale or have purple lips this time, the same symptoms frightened me because I am currently studying abroad, and medical care is very inconvenient.
I looked online and saw information about viral myocarditis, which made me worry that I might not be able to last until I return home in six months for a check-up.
The cold seems to make my palpitations worse, and I often feel fatigued.
Could this indicate a serious heart problem? I have to wait another six months to return home, and I'm very worried.
Thank you, doctor, for taking the time to read and respond!

Hello, your symptoms do not seem to indicate myocarditis.
Don't worry; it is common to experience palpitations and fatigue, especially with the current stress, reduced physical activity, and decreased stamina, which may be related to autonomic nervous system dysregulation.
Please adjust your daily routine and gradually bring your body back to balance.

More Info

Post-cold heart palpitations can be concerning, especially when accompanied by symptoms such as chest tightness, fatigue, and episodes of near-syncope (feeling faint). Your history of mitral valve prolapse (MVP) adds another layer of complexity to your situation, as this condition can sometimes lead to palpitations and other cardiovascular symptoms.
Firstly, it’s important to understand that palpitations can occur for a variety of reasons, particularly after a viral illness. Viral infections, including those that cause respiratory symptoms, can lead to inflammation of the heart muscle, a condition known as myocarditis. This can result in symptoms such as palpitations, fatigue, and even chest pain. Given that you experienced significant symptoms during your previous cold, including cold sweats and a feeling of faintness, it’s wise to consider the possibility of myocarditis, especially since you mentioned feeling very weak and having a rapid heart rate.

Your symptoms of feeling faint, having a rapid heart rate, and experiencing cold sweats are concerning. These could indicate that your heart is under stress, possibly due to an underlying issue such as myocarditis or exacerbation of your MVP. The fact that you have a history of significant symptoms during a previous illness suggests that your heart may be more sensitive to stressors, including infections.

Additionally, the fatigue and palpitations you are experiencing could also be related to anxiety, especially considering your current situation of studying abroad and the stress that can accompany that. Anxiety can manifest physically, leading to symptoms such as palpitations, chest tightness, and fatigue. However, it is crucial to rule out any serious cardiac issues first.

Given your symptoms and history, here are some recommendations:
1. Seek Medical Attention: Although you are currently abroad and may find it challenging to access healthcare, it is essential to seek medical attention if your symptoms persist or worsen. A healthcare provider can perform necessary tests, such as an electrocardiogram (EKG) and possibly an echocardiogram, to assess your heart's function and rule out any serious conditions.

2. Monitor Symptoms: Keep a detailed log of your symptoms, including when they occur, their duration, and any associated activities or stressors. This information can be invaluable for your healthcare provider.

3. Rest and Hydration: Ensure you are getting adequate rest and staying hydrated, especially after experiencing a viral illness. Fatigue can exacerbate feelings of palpitations and anxiety.

4. Avoid Stimulants: Caffeine and other stimulants can increase heart rate and exacerbate palpitations. Try to limit your intake of these substances.

5. Stress Management: Engage in relaxation techniques such as deep breathing, meditation, or gentle yoga to help manage anxiety and stress, which can contribute to palpitations.

6. Follow-Up: If you are unable to see a doctor immediately, consider scheduling a follow-up appointment as soon as you return home. It’s important to have a thorough evaluation of your heart, especially given your history of MVP and the recent symptoms.

In conclusion, while your symptoms may not necessarily indicate a severe heart problem, they warrant careful evaluation. It’s crucial to listen to your body and seek medical advice to ensure your heart health is monitored and managed appropriately. Take care of yourself, and prioritize your health during this time.
