Atrial Premature Contractions and Mitral Valve Prolapse - Cardiology

More Info

---

Atrial premature contractions (APCs) and mitral valve prolapse (MVP) are two cardiac conditions that can often coexist and may contribute to various symptoms, including palpitations and discomfort. Understanding these conditions and their management is crucial for patients experiencing related symptoms.


Atrial Premature Contractions (APCs)
APCs are early heartbeats originating in the atria, which can disrupt the normal rhythm of the heart. They are generally benign, especially in individuals without underlying heart disease. The treatment for APCs often depends on the frequency of the contractions and the presence of symptoms. In many cases, if APCs are infrequent and not causing significant symptoms, no treatment may be necessary. However, if they are frequent or symptomatic, medications such as beta-blockers (like the one you are taking, Diltiazem) may be prescribed to help manage the heart rate and reduce the frequency of these contractions.

You mentioned that you have been on medication for half a month and still experience sensations of your heart beating irregularly, particularly in the late afternoon and evening. This timing could be related to various factors, including stress, caffeine intake, or even physical activity levels during the day. It is not uncommon for patients to notice their heartbeats more during certain times of the day or during periods of stress.


Mitral Valve Prolapse (MVP)
MVP occurs when the mitral valve does not close properly, which can lead to a variety of symptoms, including palpitations, chest pain, and sometimes anxiety. In your case, the echocardiogram indicates mild MVP with mild mitral regurgitation (MR). This is generally considered a benign condition, especially if the left ventricular function is preserved (as indicated by your ejection fraction of 70.1%).


Symptoms and Management
1. Duration of Treatment: The duration of treatment for APCs can vary. If symptoms persist despite medication, your doctor may consider adjusting your treatment plan or exploring other options. Regular follow-ups are essential to monitor your condition and adjust treatment as necessary.

2. Heart Sensations: The "stabbing" sensations you feel near your heart could be related to muscle spasms, anxiety, or even the sensation of your heart beating irregularly. It is essential to differentiate between muscle pain and cardiac-related pain. If these sensations are concerning or accompanied by other symptoms (like shortness of breath or dizziness), you should seek medical advice.

3. Exercise and Activity: Engaging in physical activity, such as playing basketball or going for walks, can be beneficial. Exercise is known to help reduce anxiety and improve overall cardiovascular health. However, it is essential to listen to your body. If you notice that certain activities exacerbate your symptoms, it may be wise to modify your exercise routine. Always consult with your healthcare provider before making significant changes to your activity level, especially with your existing conditions.


Conclusion
In summary, while APCs and MVP can cause discomfort, they are often manageable with appropriate medical care and lifestyle adjustments. Regular monitoring and open communication with your healthcare provider are key to effectively managing your symptoms. If you continue to experience significant discomfort or if your symptoms change, it is crucial to revisit your healthcare provider for further evaluation and potential adjustments to your treatment plan.
