What does a Holter monitor show about premature beats?

Patient's question:

In early January, I had gastroenteritis with a fever, and after a while, I took traditional Chinese medicine and other treatments. Later, I always felt uncomfortable physically, and then I started experiencing some palpitations. I felt my heartbeat was very noticeable, sometimes like a skipped beat or a heavier sensation. I went to the hospital for thyroid tests, which were normal, along with normal troponin levels and a normal echocardiogram. I also had a 24-hour ECG, which showed sinus rhythm with occasional premature ventricular beats (PVCs), around 300-400 episodes in 24 hours, and intermittent mild T-wave changes. Now, I feel that the heartbeat is less noticeable, but sometimes it still feels heavy. Can the report indicate whether the PVCs are organic or functional?

Doctor's answer:

Okay, here is the translation following your instructions:
A single ECG cannot confirm whether the heart truly has organic inflammation; other careful tests are needed to confirm if there is organic inflammation.
If confirmation is needed, one can undergo tests like echocardiography, cardiac magnetic resonance imaging (MRI), etc. However, generally speaking, occasional ventricular premature beats (VPBs) are not harmful, and you really don't need to worry too much about this.
The above is advice regarding the question "Can a dynamic ECG determine if premature beats are organic or functional?". It is hoped this is helpful to you. Wishing you health!
