Palpitations and dizziness?

Dr.
Lin: Hello, I have been experiencing palpitations for many years, occasionally without warning.
Recently, over the past three months, I have started to feel dizzy, followed by more frequent palpitations.
I have seen a doctor, and the dizziness has resolved, but the palpitations persist.
The doctor listened to my heart sounds and found no issues, and suggested that I consider an ambulatory Holter monitor.
I also underwent a general health check, and my red blood cell count was slightly low at 3.78 (normal range 3.92-6).
I would like to ask: 1.
Is this indicative of anemia? Can I take iron and folic acid supplements? 2.
The white part of my nail bed has disappeared, and I am prone to hangnails, which has become unusual and hard to describe.
Could this be a vitamin deficiency? 3.
Are the palpitations caused by anemia? Besides wearing a monitor, are there other methods to check? 4.
Is swimming frequently suitable for me? Thank you for your response.

Hello: Palpitations are a subjective sensation experienced by individuals, where the heartbeat may be too fast, too slow, or even normal.
Therefore, palpitations do not necessarily indicate arrhythmia.
In fact, based on my experience, many palpitations are simply caused by excessive stimulation of the autonomic nervous system, which is related to daily life stress, lifestyle (such as staying up late and insomnia), and diet (like coffee and tea).
An ambulatory electrocardiogram can be helpful for diagnosis, but it is best to have symptoms occur during the examination.
Unfortunately, many patients often do not experience symptoms while being tested.
Your symptoms may not be caused by anemia; typically, symptoms from anemia occur when hemoglobin levels drop below 10 g/dL (you did not provide hemoglobin data).
A slightly low red blood cell count should not cause symptoms.
Taking folic acid and iron supplements is only effective if there is a deficiency; without confirmed deficiency, supplementation is not beneficial.
Additionally, you mentioned changes in your nails; certain vitamin deficiencies can indeed cause changes in nails, but in modern diets, unless there are other underlying conditions, vitamin deficiencies are almost nonexistent.
Swimming is a great form of exercise as it is an isotonic activity that is less likely to increase heart rate and is very beneficial for lung capacity.
Wishing you all the best.

More Info

Palpitations and dizziness can be concerning symptoms that may arise from various underlying conditions. Based on your description, it seems you have been experiencing palpitations for several years, with a recent increase in frequency alongside episodes of dizziness. Let's address your questions one by one and provide some additional context regarding your symptoms.

1. Is the low red blood cell count indicative of anemia? Can I take iron and folic acid supplements?
Your red blood cell count of 3.78 is indeed slightly below the normal range (3.92-6.0), which could suggest a mild form of anemia. Anemia can lead to symptoms such as fatigue, palpitations, and dizziness due to reduced oxygen delivery to tissues. Iron deficiency is a common cause of anemia, and taking iron supplements can be beneficial if this is the case. Folic acid is also important for red blood cell production, so a combined supplement may be helpful. However, it is essential to consult with your healthcare provider before starting any supplements, as they can perform further tests to determine the exact cause of your anemia and recommend appropriate treatment.

2. The loss of the white part of the nail and the growth of hangnails: Is this a vitamin deficiency?
Changes in nail appearance can be indicative of various nutritional deficiencies or health conditions. The loss of the white part of the nail (lunula) and the development of hangnails may suggest a deficiency in certain vitamins or minerals, such as biotin, zinc, or even iron. Additionally, stress and dehydration can also affect nail health. It would be wise to discuss these changes with your doctor, who may recommend blood tests to check for deficiencies and suggest dietary changes or supplements as needed.

3. Could palpitations be caused by anemia? Are there other methods to check for heart issues besides wearing a monitor?
Yes, anemia can indeed cause palpitations. When the body is low on red blood cells, the heart has to work harder to pump oxygenated blood, which can lead to an increased heart rate and palpitations. Besides wearing a Holter monitor, which records your heart's activity over a period, other diagnostic tests can include an electrocardiogram (ECG), echocardiogram, or stress tests. These tests can help assess your heart's structure and function, and determine if there are any underlying cardiac issues contributing to your symptoms.

4. Is swimming a suitable activity for me?
Swimming is generally a low-impact exercise that can be beneficial for cardiovascular health. However, if you are experiencing frequent palpitations and dizziness, it is crucial to consult with your healthcare provider before engaging in any strenuous activities. They can evaluate your overall health and determine if swimming or other forms of exercise are appropriate for you. If cleared, swimming can help improve your cardiovascular fitness and overall well-being.

In summary, your symptoms of palpitations and dizziness could be related to anemia, and addressing any nutritional deficiencies may help alleviate these issues. It is essential to work closely with your healthcare provider to monitor your symptoms, conduct necessary tests, and develop a comprehensive treatment plan tailored to your needs. Regular follow-ups and open communication with your doctor will ensure that any changes in your condition are promptly addressed, allowing you to maintain a healthy and active lifestyle.
