After radiofrequency ablation of premature ventricular contractions, the heart beats faster after meals, may be physiological factors, if the symptoms persist, need to be reviewed to rule out the possibility of recurrence. After radiofrequency ablation for premature ventricular contractions, the rapid heartbeat after meals is considered to be a physiological phenomenon if it is only a transient phenomenon. After eating a large amount of food quickly into the stomach, the automatic regulation system will mobilize a large amount of blood circulation to the stomach to help digestion, which will lead to a corresponding decrease in the blood supply to the heart, resulting in rapid heartbeat, which does not require special treatment. In patients after radiofrequency ablation for premature ventricular contractions, a sustained rapid heartbeat after eating also depends on the duration of the procedure. If this situation occurs two or three days after the operation, it is considered that it has not fully recovered; if it still occurs a long time after the operation and the patient has obvious discomfort, it is necessary to go to the hospital for examination to exclude the possibility of recurrence. Patients with premature ventricular contractions need to recuperate for a period of time after radiofrequency ablation, not to exercise strenuously in the short term, pay attention to rest, eat a light diet, keep a happy mood, and need to take medication according to the doctor’s instructions after the operation.
