Palpitations and Rapid Heartbeat: Causes and Solutions - Cardiology

More Info

---

Understanding palpitations and rapid heartbeat can be quite concerning, especially when accompanied by feelings of anxiety or panic. Based on your description, it seems you are experiencing episodes of palpitations, where your heart rate spikes to 120-150 beats per minute, along with sensations of fear and dizziness. This can be distressing and may lead you to wonder about the underlying causes and potential solutions.

Palpitations can arise from a variety of factors, including physiological, psychological, and environmental influences. In your case, the diagnosis of mitral valve prolapse (MVP) is significant. MVP is a condition where the mitral valve does not close properly, which can lead to a range of symptoms, including palpitations, anxiety, and even chest discomfort. It is relatively common and often benign, but it can sometimes be associated with arrhythmias, which are irregular heartbeats that can cause the heart to race.

Your experience of palpitations occurring during moments of stress or anxiety is not uncommon. The autonomic nervous system, which regulates involuntary bodily functions, plays a crucial role in how your body responds to stress. When you are anxious or under pressure, the sympathetic nervous system can become activated, leading to an increase in heart rate and the sensation of palpitations. This is often referred to as a "fight or flight" response, where the body prepares to respond to perceived threats.

In addition to psychological factors, certain lifestyle choices can exacerbate palpitations. Caffeine, nicotine, and alcohol are known stimulants that can increase heart rate and trigger palpitations. Stress management techniques, such as mindfulness, meditation, and regular physical activity, can help mitigate these episodes. It is also essential to maintain a healthy diet and stay hydrated, as dehydration can lead to electrolyte imbalances, which may contribute to heart rhythm disturbances.

Given that you have been prescribed medication (心康樂) for your condition, it is crucial to adhere to your doctor's recommendations and report any changes in your symptoms. Medications can help regulate heart rhythm and reduce the frequency of palpitations. However, if you continue to experience significant episodes of rapid heartbeat, dizziness, or feelings of panic, it is advisable to follow up with your healthcare provider. They may recommend further evaluation, such as an echocardiogram or Holter monitor, to assess your heart's function and rhythm over a more extended period.

In summary, while your symptoms may be related to mitral valve prolapse and autonomic nervous system dysregulation, it is essential to consider the broader context of your health. Stress management, lifestyle modifications, and adherence to prescribed treatments can significantly improve your quality of life. If your symptoms persist or worsen, do not hesitate to seek further medical advice. Your health and well-being are paramount, and understanding the underlying causes of your symptoms is the first step toward effective management.
