VPC: Impact on Heart Function and Treatment Options

Ventricular Premature Contractions (VPC)

I have been diagnosed with VPC (ventricular premature contractions) for over 8 years.
During this time, I have relied on medication to alleviate uncomfortable symptoms such as palpitations, chest tightness, chest pain, shortness of breath, noticeable pulsations in the left chest, and dizziness, which have affected my daily life and work.
Since I do not want to take medication long-term and after receiving my physician's advice, I underwent a 3D catheter ablation procedure (under general anesthesia).
Initially, a 24-hour Holter monitor recorded approximately 35,000 occurrences, but after the ablation, a follow-up check showed there were still 20,000 occurrences (in 24 hours) over a month later.
I still feel symptoms, although they have somewhat diminished, but I notice that my heart rate increases significantly after exercise, and I still need to take medication when I feel unwell.
I have some questions for the physician: 1.
Will this abnormal frequency affect heart function? 2.
Is there a need for a second ablation procedure? 3.
What are the long-term effects of taking antiarrhythmic medication and beta-blockers on the body? I apologize for asking so many questions, and I appreciate the physician's patience.
Thank you!

Hello, this abnormal frequency will not affect heart function, so just take the medication! There should be no need for a second catheter ablation at this time.
Long-term use of antiarrhythmic medications and beta-blockers has minimal impact on the body, as these drugs are metabolized quickly and do not accumulate significantly.
You can start the medication and observe your condition.

More Info

Ventricular premature contractions (VPCs) are a common type of arrhythmia characterized by early heartbeats originating in the ventricles. While they can be concerning, especially for those experiencing symptoms like palpitations, chest discomfort, or dizziness, it's important to understand their implications on heart function and the available treatment options.

1. Impact of VPCs on Heart Function: Generally, isolated VPCs, especially when occurring in low frequencies, do not significantly impact overall heart function. In your case, the initial 24-hour Holter monitor showed a high frequency of VPCs (35,000), which is indeed concerning, but after the catheter ablation procedure, the frequency decreased to 20,000. This reduction indicates that the procedure was somewhat effective, even if symptoms persist. The heart is quite resilient, and many individuals can have VPCs without any detrimental effects on heart structure or function. Your echocardiogram results, which indicate normal left and right ventricular function, further support that your heart is functioning well despite the presence of VPCs.

2. Need for Further Ablation: Whether or not a second ablation is necessary depends on several factors, including the frequency of VPCs, the severity of symptoms, and the overall impact on your quality of life. If your symptoms remain bothersome and significantly affect your daily activities, discussing the possibility of a second procedure with your cardiologist may be warranted. However, it is also essential to weigh the risks and benefits of additional procedures against the current symptomatology and heart function.

3. Long-term Medication Effects: Regarding the long-term use of antiarrhythmic medications (like rhythm control drugs) and beta-blockers, these medications can be beneficial in managing symptoms and reducing the frequency of VPCs. Most patients tolerate these medications well, and they are generally considered safe for long-term use. However, like all medications, they can have side effects. Beta-blockers, for instance, can cause fatigue, dizziness, or a slower heart rate, while antiarrhythmics may have their own set of potential side effects, including the risk of new arrhythmias. Regular follow-ups with your healthcare provider are essential to monitor for any adverse effects and to adjust medications as necessary.

In conclusion, while VPCs can be alarming, especially when symptomatic, they often do not pose a significant risk to heart function in the absence of underlying heart disease. It is crucial to maintain open communication with your healthcare provider regarding your symptoms, treatment options, and any concerns you may have. Lifestyle modifications, such as reducing caffeine intake, managing stress, and regular exercise, can also play a vital role in managing symptoms. Always consult your physician before making any changes to your treatment plan or lifestyle.
