Persistent palpitations


Hello, doctor! About a month and a half ago, I started to feel my heartbeat before going to bed (is this palpitations?).
The rate isn't particularly fast; I just feel my heart beating.
It's intermittent, so I didn't pay much attention to it.
However, since last week, I've been experiencing palpitations almost every night before sleep, and it's been a week straight! It's not just before bed; I also feel palpitations when I wake up or during quiet moments, and sometimes I even experience slight numbness in my hands.
Should I seek medical attention? If this is normal, will the palpitations gradually subside? Because of the palpitations, I've been sleeping poorly every night.
I am overweight and I enjoy coffee; could this be affecting me? (I just had a physical examination two months ago, and aside from being overweight, everything, including my heart and blood pressure, was normal.
So I'm very worried about what could be causing the palpitations.) Additionally, if I have palpitations, can I go running or engage in vigorous exercise? I've started exercising to lose weight, but the palpitations have made me hesitant to continue, as I'm afraid it might be too stimulating.
Thank you!

Experiencing persistent palpitations can be concerning, and it's important to understand when to seek medical advice. Palpitations are often described as the sensation of feeling your heart beating, which can occur in various forms, such as a racing heart, fluttering, or a feeling of skipped beats. While occasional palpitations are common and usually harmless, persistent or frequent occurrences warrant further evaluation.

In your case, the fact that you have been experiencing palpitations almost every day for a week, particularly when you are at rest or trying to sleep, is significant. The additional symptoms of hand numbness and poor sleep quality further complicate the situation. Although you mentioned that a recent health check-up showed normal heart function and blood pressure, the persistence of your symptoms suggests that it would be prudent to consult a healthcare professional.

Several factors could contribute to your palpitations. Caffeine consumption is known to stimulate the heart and can lead to increased heart rate and palpitations, especially if consumed in large quantities. Additionally, being overweight can increase the workload on your heart, potentially leading to feelings of palpitations. Stress and anxiety can also play a significant role in exacerbating these sensations, particularly if you are feeling anxious about your health.

When considering whether to seek medical advice, it is essential to evaluate the following:
1. Frequency and Duration: If your palpitations are frequent and last for extended periods, it is advisable to seek medical attention. Continuous symptoms over a week, especially if they are worsening, should not be ignored.

2. Associated Symptoms: If you experience other symptoms such as chest pain, shortness of breath, dizziness, or fainting, you should seek immediate medical care. These could indicate a more serious underlying condition.

3. Impact on Daily Life: If your palpitations are affecting your ability to sleep or engage in daily activities, this is another reason to consult a healthcare provider.

4. Underlying Health Conditions: Given your history of being overweight and your caffeine intake, discussing these factors with a doctor can help identify potential lifestyle modifications that may alleviate your symptoms.

In terms of exercise, it is generally advisable to engage in physical activity, as it can improve cardiovascular health and aid in weight management. However, given your current symptoms, it would be wise to approach exercise cautiously. Start with low-intensity activities, such as walking or gentle stretching, and monitor how your body responds. If you notice that exercise exacerbates your palpitations, it would be best to stop and consult a healthcare professional before resuming any vigorous activity.

In conclusion, while occasional palpitations can be benign, the persistence and frequency of your symptoms, along with associated factors like hand numbness and sleep disturbances, suggest that seeking medical advice is a prudent course of action. A healthcare provider can perform a thorough evaluation, which may include an electrocardiogram (ECG), blood tests, or a Holter monitor to assess your heart's rhythm over a period of time. This will help determine the underlying cause of your palpitations and guide appropriate treatment or lifestyle changes. Remember, it is always better to err on the side of caution when it comes to your health.
