Chest tightness, difficulty breathing, and feeling faint?


In December 2022, while driving, I suddenly felt a tightness in the epigastric area, followed by dizziness.
I didn't experience vertigo, but I felt like I couldn't get enough air and was about to faint.
I pulled over and asked someone to assist me in calling an ambulance.
Subsequent emergency blood tests and an electrocardiogram (ECG) showed normal results, ruling out myocardial infarction.
Later, during an outpatient visit, I underwent a 24-hour ECG monitoring.
During this period, I felt unwell and pressed the record button, but the doctor later indicated that the ECG results were normal and there were no arrhythmias.
He suggested that I could use my Apple Watch to record any discomfort since it may not coincide with the ECG monitoring.
Today, I specifically recorded my discomfort and noticed that the ECG from the Apple Watch showed several irregularities.
I would like to inquire whether these recorded signs warrant a follow-up visit to the hospital.
Although previous tests were normal, I still feel unwell.
I often experience tightness in the epigastric area (xiphoid process) and have difficulty breathing, along with feelings of dizziness.

I would like to ask the doctor, in the PDF, what could be the cause of the sudden fluctuations observed?

It is recommended that you visit a hospital for a consultation and undergo a 24-hour Holter monitor test.

When experiencing chest tightness and breathing difficulties, it is crucial to understand the potential underlying causes and when to seek medical help. Your description of feeling tightness in the chest, dizziness, and difficulty breathing, particularly after a stressful episode, raises several important considerations.

Firstly, it is essential to recognize that chest tightness can stem from various sources, including anxiety, panic attacks, respiratory issues, or cardiovascular problems. Given your previous experiences, such as the episode while driving that led to emergency care, it is understandable to be concerned about your symptoms. The fact that initial tests, including blood tests and an electrocardiogram (ECG), returned normal results is reassuring, but it does not entirely rule out the possibility of intermittent issues that may not be captured during those tests.

Anxiety and panic attacks can manifest physically, often leading to sensations of tightness in the chest and difficulty breathing. These symptoms can be exacerbated by stress, as you mentioned experiencing anxiety related to life circumstances. In such cases, the body may enter a heightened state of alertness, leading to hyperventilation, which can further contribute to feelings of dizziness and breathlessness. It is important to note that while these symptoms can be distressing, they are often temporary and can be managed with appropriate techniques, such as deep breathing exercises or mindfulness practices.

However, given your ongoing symptoms and the irregularities noted in your Apple Watch recordings, it is advisable to follow up with your healthcare provider. The irregular heart rhythms you observed could indicate an underlying issue that warrants further investigation. Even if previous tests were normal, your symptoms and the new data from your device should be taken seriously. It is not uncommon for patients to experience symptoms that do not align perfectly with test results, and your healthcare provider may recommend additional monitoring or tests to ensure that there are no underlying cardiac issues.

In terms of what to do next, consider the following steps:
1. Document Symptoms: Keep a detailed record of your symptoms, including when they occur, their duration, and any associated activities or stressors. This information can be invaluable for your healthcare provider.

2. Follow-Up Appointment: Schedule a follow-up appointment with your primary care physician or a cardiologist. Bring your Apple Watch data and any other relevant information to discuss your ongoing symptoms.

3. Consider Mental Health Support: If anxiety is a contributing factor, consider speaking with a mental health professional. Cognitive-behavioral therapy (CBT) and other therapeutic approaches can be effective in managing anxiety and its physical manifestations.

4. Lifestyle Modifications: Engage in regular physical activity, practice relaxation techniques, and ensure you are getting adequate sleep. These lifestyle changes can help reduce anxiety and improve overall well-being.

5. Emergency Situations: If you experience severe symptoms, such as chest pain, significant shortness of breath, or fainting, do not hesitate to seek emergency medical attention. It is always better to err on the side of caution.

In conclusion, while your previous tests have not indicated a serious condition, the persistence of your symptoms and the new data from your Apple Watch warrant further evaluation. It is essential to communicate openly with your healthcare provider about your concerns and experiences to ensure you receive the appropriate care and support. Remember, your health is paramount, and addressing these symptoms proactively can lead to better outcomes.
