People with frequent ventricular premature beats have colds, which may worsen the premature beats. Whether or not taking anti-inflammatory medication makes premature beats worse is not supported by evidence and has no theoretical basis. Premature ventricular contractions are a type of arrhythmia. If you notice frequent ventricular premature beats, you should formally consult a cardiologist for a 24-hour ambulatory electrocardiogram, cardiac ultrasound, and laboratory tests for electrolytes and thyroid function. If there is no structural abnormality in the myocardium, and electrolytes and thyroid function are normal, the occurrence of premature ventricular contractions is usually associated with smoking and drinking alcohol, and drinking stimulating beverages such as strong tea, strong coffee, and cola. Exhaustion, anxiety, and poor rest can lead to an increase in premature beats. Poor rest and discomfort in patients after a cold may also theoretically lead to an increase in premature beats. Taking anti-inflammatory medication for a cold, anti-inflammatory medication itself is not known to affect premature beats. If you have an increase in premature beats after catching a cold, you should go to the cardiology department in a timely and regular manner.
