Midday Palpitations: Causes and Solutions

Palpitations are likely to occur around noon?

Hello, doctor.
I would like to ask about a concern.
Two years ago, I had an echocardiogram that indicated my mitral valve was elongated, but it was said to not affect my normal life.
Recently, after changing jobs about three months ago, I have noticed that my heart rate increases around noon, and I can feel my heart beating.
I tend to be anxious, and the more I focus on my heartbeat, the faster it seems to go.
Sometimes, when I'm not paying attention, it appears to return to normal, but there are times when I suddenly experience palpitations even while just sitting.
I have not been feeling well physically and have not been getting much sunlight or eating fruits, which makes me wonder if my cardiovascular and pulmonary function has declined due to a lack of exercise, leading to these symptoms.
I also have gastroesophageal reflux disease (GERD), but the palpitations mostly occur around noon, and occasionally at home, I suddenly feel my heart racing.
I would appreciate your help in addressing these concerns.
Thank you.

Hello, it is possible that you are experiencing gastroesophageal reflux or autonomic dysregulation, rather than a heart condition.
Generally speaking, the functions of internal organs such as the heart and lungs are not time-dependent; it would be unreasonable for their functions to decline precisely at noon.
The likelihood of autonomic dysregulation is higher.

More Info

Midday palpitations can be a concerning symptom, especially when they occur regularly and are accompanied by feelings of anxiety or discomfort. Based on your description, it seems that your palpitations are linked to a combination of factors, including your previous heart condition, lifestyle changes, and possibly anxiety.

Firstly, let's address the heart condition you mentioned. A longer mitral valve, as noted in your echocardiogram, can sometimes lead to mitral valve prolapse, which may cause palpitations. However, if your healthcare provider indicated that it does not affect your normal life, it is likely not the primary cause of your current symptoms. It’s essential to keep regular follow-ups with your cardiologist to monitor any changes in your heart condition.

The onset of palpitations around midday could be related to several factors. One possibility is the stress associated with your new job. Stress and anxiety can significantly impact heart rate and rhythm. When you become more aware of your heartbeat, it can create a cycle of anxiety that exacerbates the sensation of palpitations. This is often referred to as "psychophysiological" palpitations, where the awareness of the heartbeat leads to increased anxiety, which in turn can cause the heart to beat faster.

Additionally, lifestyle factors such as diet, hydration, and physical activity play a crucial role in heart health. You mentioned that you have not been exercising regularly and have not been consuming fruits and vegetables, which are vital for overall health. A lack of physical activity can lead to decreased cardiovascular fitness, which may contribute to feelings of palpitations, especially during times of stress. Regular exercise can help improve heart health and reduce anxiety levels.

Moreover, you mentioned experiencing gastroesophageal reflux disease (GERD), which can also cause palpitations. Acid reflux can irritate the vagus nerve, which runs from the brain to the abdomen and can influence heart rate. If your palpitations coincide with episodes of reflux, it may be worth discussing with your healthcare provider to see if managing your GERD could alleviate some of your symptoms.

To address your midday palpitations, consider the following strategies:
1. Stress Management: Incorporate relaxation techniques such as deep breathing exercises, meditation, or yoga into your daily routine. These practices can help reduce anxiety and improve your overall sense of well-being.

2. Regular Exercise: Aim for at least 150 minutes of moderate aerobic activity each week. Exercise not only strengthens the heart but also helps reduce anxiety and improve mood.

3. Healthy Diet: Focus on a balanced diet rich in fruits, vegetables, whole grains, and lean proteins. Staying hydrated is also essential, as dehydration can lead to increased heart rate.

4. Monitor Triggers: Keep a diary of when your palpitations occur, noting any associated activities, meals, or stressors. This can help identify patterns and triggers.

5. Consult Your Doctor: Since you have a history of heart concerns, it’s crucial to discuss your symptoms with your healthcare provider. They may recommend further evaluation, such as a Holter monitor, to assess your heart rhythm over a 24-hour period.

In conclusion, while midday palpitations can be distressing, they are often manageable through lifestyle changes and stress reduction techniques. It’s essential to maintain open communication with your healthcare provider to ensure that any underlying conditions are appropriately monitored and treated.
