What causes palpitations and PVCs after eating food?

Hello,

Welcome to icliniq.com.

Holter monitoring reports are normal (attachment removed to protect the patient's identity). Rare episodes of PVC (premature ventricular contractions) are normal occurrences. Thank you.

Sinus arrhythmia is a normal and healthy arrhythmia. It indicates the autonomic nervous system is working fine. Regarding PVCs or palpitations after eating meals can be due to food allergy to certain foods, consumption of caffeine or caffeinated beverages. This can cause an increase in heart rate and result in palpitations, and meals high in carbohydrates especially at times when your blood sugar levels are relatively low cause sudden spike in blood sugar and cause palpitations or PVCs. You may take low-dose of beta-blocker medicine. These are medicines that lower heart rate, and control PVCs. Take a tablet of Metoprolol tartrate 25 mg half tablet twice a day, then the dose may be increased according to response every week. Thank you.

No, a small number of PVCs are not a serious issue. Your seven-day Holter test showed only 27 PVCs and your symptoms did not necessarily correspond to these PVCs. Your average heart rate was 78 bpm, which is normal. You should avoid processed foods and limit spicy foods, not eat up to a full stomach, always keep space, and drink plenty of water. Note what foods make you feel palpitations, avoid these foods. Sometimes gastric acid reflux can cause palpitations. Take a tablet of Omeprazole 20 mg capsule once a day. Your echo is normal means the mechanical function of the heart is normal. Thank you.

Palpitations are commonly due to cardiac arrhythmia and the most reliable test for detecting arrhythmia is Holter monitoring. If there are significant numbers of PVCs, then echocardiography is done to see any structural heart disease. Both are normal in your case. Isolated PVCs are not dangerous. They can be controlled with some preventive steps I described already and medicines like beta blockers. Another test for PVCs is serum potassium and magnesium levels. Low levels may cause PVCs. As a last resort when PVCs are large in number in 24 hours and are symptomatic, the cardiac electrophysiological study is done and the focus of PVCs is detected and ablated with radiofrequency catheter ablation. This usually cures PVCs in more than 95 % of cases but has a small risk of heart block. Thank you.
