Is Your Heart Palpitations Serious? Mitral Valve Prolapse and Anemia - Cardiology

More Info

---

Heart palpitations can be concerning, especially when they are accompanied by other symptoms such as dizziness, chest discomfort, or a feeling of breathlessness. In your case, you have a history of mild mitral valve prolapse (MVP) and hereditary anemia, both of which can contribute to your symptoms.

Mitral valve prolapse is a condition where the mitral valve does not close properly, which can lead to a variety of symptoms, including palpitations, chest pain, and fatigue. In many cases, MVP is benign and does not require treatment, but it can sometimes be associated with arrhythmias (irregular heartbeats). The palpitations you experience, especially after exercise, could be related to the MVP, as the heart may respond differently under stress. It’s also worth noting that MVP can sometimes cause a sensation of the heart beating harder or faster, which you described.

Anemia, particularly hereditary forms, can also lead to palpitations. When your body lacks sufficient red blood cells to carry oxygen, your heart has to work harder to supply oxygen to your tissues, which can result in an increased heart rate or palpitations. The fact that you mentioned feeling dizzy after exercise could be linked to your anemia, especially if your hemoglobin levels are low. This dizziness can occur due to inadequate oxygen delivery to the brain during physical exertion.

Regarding your heart rate, a resting heart rate of 53 beats per minute is considered bradycardic (lower than normal). While athletes often have lower resting heart rates due to improved cardiovascular efficiency, it’s important to ensure that this isn’t causing your symptoms. The fact that you experience palpitations and a feeling of tightness in your chest, particularly after using Inderal (a beta-blocker), suggests that your heart's response to stress or exertion may need further evaluation.

The 24-hour Holter monitor you underwent will provide valuable information about your heart rhythm over an extended period. If the report indicates irregularities, it may warrant further investigation, especially if you continue to experience symptoms. The mention of an unclear P wave on your ECG could indicate issues with atrial conduction, which may or may not be significant. It’s essential to discuss these findings with your healthcare provider to understand their implications fully.

In summary, your symptoms of palpitations, dizziness, and chest discomfort could be related to your mitral valve prolapse and anemia. It’s crucial to follow up with your healthcare provider to discuss your Holter monitor results and consider further evaluation, such as echocardiography or additional blood tests to assess your anemia. If your symptoms persist or worsen, or if you experience new symptoms such as severe chest pain or shortness of breath, seek immediate medical attention.

Maintaining a healthy lifestyle, including regular exercise and a balanced diet, is essential. However, given your history and current symptoms, it’s advisable to have a thorough evaluation to ensure your heart health is managed appropriately. Your concerns are valid, and it’s essential to address them with your healthcare provider to ensure you feel confident and secure about your health, especially while serving in the military.
