Rapid Heartbeat and Chest Pain in Teens: Causes and Concerns

Recently, I've been experiencing a rapid heartbeat and occasional sharp pains?

Hello Doctor, I am 15 years old and in the ninth grade.
Recently, I have been experiencing sudden palpitations even when I am not engaging in any strenuous activities, such as while eating or taking the MRT.
My pulse has been measured at over 100 beats per minute, and it makes me feel very uncomfortable, often accompanied by cold sweats.
I have a history of anxiety and previously took medication for it, but I have stopped for a while.
Now, I occasionally feel a sharp pain in my left chest, which makes me very anxious and worried about my health.
In August, I had an electrocardiogram (ECG) and an echocardiogram, both of which were reported as normal.
Since I have a history of arrhythmia, my doctor prescribed Inderal, but I am hesitant to take it (I am unsure when it would be appropriate to take it).
Additionally, I am unsure what medication to take for the chest pain.
Recently, I have also been experiencing soreness in my left arm and back, which I suspect may be due to a sports injury, but I am worried it could be related to my heart (I occasionally feel pain in the front).
My parents say I am overthinking things and feel there is no need for me to see a doctor.
I would like to know what you think might be the issue.

Hello, you have undergone an electrocardiogram and echocardiogram, both of which are normal, indicating that your heart is healthy.
The anxiety you are experiencing is causing autonomic nervous system dysregulation, so there is no need to be tense.
You can take Inderal when you feel uncomfortable; it is not addictive or habit-forming.
As for heart issues, it is normal to occasionally experience chest pain that comes and goes; there is no need to worry.
Changhua Hospital cares about you.

More Info

Understanding rapid heartbeat and chest pain in teenagers can be quite concerning, especially when these symptoms occur without any obvious triggers. As a 15-year-old experiencing sudden palpitations and chest discomfort, it's essential to consider both physiological and psychological factors that may contribute to your symptoms.

Firstly, it's important to note that your heart rate of over 100 beats per minute (bpm) can be classified as tachycardia, which can occur for various reasons. In your case, since you mentioned that these episodes happen during non-strenuous activities, it could be linked to anxiety or stress. Anxiety can significantly impact the autonomic nervous system, leading to increased heart rates and sensations of palpitations. This is particularly relevant given your history of anxiety and previous use of medication for it.

The fact that you have undergone an electrocardiogram (ECG) and echocardiogram, both of which returned normal results, is reassuring. These tests are crucial in ruling out structural heart problems or significant arrhythmias. However, your mention of having a history of arrhythmia and being prescribed Inderal (propranolol) suggests that your healthcare provider is aware of your heart's electrical activity and is taking steps to manage it. Inderal is often used to help control heart rate and reduce anxiety symptoms, and it can be taken as needed, especially during episodes of increased heart rate or anxiety.

Regarding your left chest pain and discomfort in your left arm and back, these symptoms can often be musculoskeletal in nature, especially if they are related to physical activity or posture. However, it is crucial to differentiate between musculoskeletal pain and cardiac-related pain. The fact that you experience these symptoms intermittently and they are not accompanied by other alarming signs (such as shortness of breath, severe dizziness, or fainting) is a positive indicator. Nonetheless, if the pain persists or worsens, it would be wise to consult a healthcare professional for further evaluation.

Your parents' perspective that you might be overthinking your symptoms is common among caregivers, especially when they see their child experiencing anxiety. However, your concerns are valid, and it's essential to listen to your body. If you feel that your symptoms are affecting your daily life or causing significant distress, seeking a second opinion or further evaluation from a cardiologist or a mental health professional could provide you with peace of mind.

In terms of lifestyle modifications, consider incorporating regular physical activity, which can help reduce anxiety and improve cardiovascular health. Additionally, practicing relaxation techniques such as deep breathing, meditation, or yoga can be beneficial in managing anxiety and its physical manifestations. Reducing caffeine intake and ensuring adequate hydration can also help in managing heart rate and overall well-being.

In summary, while your symptoms may be related to anxiety and stress, it is essential to remain vigilant and proactive about your health. Continue to monitor your symptoms, and do not hesitate to seek medical advice if you feel it is necessary. Your health is paramount, and understanding the interplay between anxiety and physical symptoms is crucial in managing your overall well-being.
