Dizziness and Palpitations: Heart and Lung Health Concerns

Dizziness and rapid heartbeat?

Hello, doctor.
Due to feeling unwell previously, I haven't exercised or been exposed to sunlight for about two years.
Does this mean that my cardiovascular and pulmonary functions may have deteriorated? Is my dizziness also related to poor cardiovascular and blood circulation? I started using a treadmill for about 15 minutes since the day before yesterday; will this help improve my cardiovascular and blood circulation gradually? I often experience symptoms like dizziness and headaches, and sometimes palpitations, especially during my lunch break at work when I suddenly feel my heart racing, even though I'm just resting.
After about 30 minutes, it usually subsides.
The dizziness often feels like heaviness in my head and fatigue.
I also have gastrointestinal issues, which sometimes cause pain in the area below my left chest and near my left clavicle.
Could these symptoms indicate a heart problem, or are they more likely due to posture and nerve issues? Given my age, could it be that my tendency to get anxious is the biggest contributing factor? Sometimes these episodes occur suddenly, and my emotions can fluctuate significantly.
Thank you for your assistance, doctor.

Hello, a decrease in cardiovascular fitness is inevitable without physical activity.
Starting to use a treadmill can gradually improve both cardiovascular function and blood circulation, which is a positive step.
Please continue with this.
Other symptoms you described seem to be influenced by your tendency to get easily anxious; it is advisable to have a stress relief outlet.
The pain in the lower left chest and collarbone area does not appear to be related to heart issues.
However, if discomfort persists, it is recommended to seek further evaluation at an outpatient clinic.

More Info

Understanding dizziness and palpitations can be complex, as these symptoms can stem from various underlying health issues, particularly concerning heart and lung health. Based on your description, it seems that you have been experiencing a combination of dizziness, palpitations, and discomfort in the chest area, which can indeed be linked to cardiovascular and pulmonary function.

Firstly, a lack of physical activity and exposure to sunlight over an extended period can negatively impact your cardiovascular and pulmonary health. Regular exercise is crucial for maintaining heart health, improving circulation, and enhancing lung function. When you do not engage in physical activity, your cardiovascular system may become less efficient, leading to symptoms such as dizziness and palpitations. This inefficiency can also result in decreased oxygen delivery to your tissues, contributing to feelings of fatigue and dizziness.

The symptoms you describe, particularly the episodes of dizziness and palpitations, could be related to several factors. Dizziness can arise from inadequate blood flow to the brain, which might be due to low blood pressure, dehydration, or even anxiety. Palpitations, or the sensation of a racing heart, can occur in response to stress, anxiety, or even after consuming caffeine or other stimulants. Given that you mentioned feeling your heart race during rest, it could be a sign of anxiety or a response to stress, especially if you have been feeling tense or anxious.

Regarding your recent decision to start using a treadmill for about 15 minutes, this is a positive step towards improving your cardiovascular fitness. Gradually increasing your physical activity can help enhance your heart and lung function over time. However, it is essential to listen to your body; if you experience significant discomfort or worsening symptoms during exercise, it would be wise to consult with a healthcare professional before continuing.

The discomfort you feel in the left chest area and near the collarbone could be related to muscular tension, posture, or even gastrointestinal issues, especially if you have a history of gastrointestinal discomfort. Stress and anxiety can also manifest physically, leading to muscle tension that may cause pain in various areas, including the chest.

As for your concerns about whether these symptoms indicate a serious heart condition, it is reassuring that your heart function appears normal based on previous evaluations. However, if you continue to experience these symptoms, it may be beneficial to undergo further evaluation, including a thorough cardiovascular assessment, to rule out any underlying issues.

In summary, while your symptoms may not necessarily indicate a severe heart condition, they warrant attention, especially given your history of inactivity and stress. Incorporating regular physical activity, managing stress, and maintaining a healthy lifestyle can significantly improve your overall health. If symptoms persist or worsen, seeking medical advice is crucial to ensure that any potential health issues are addressed appropriately.
