Haven't felt well for about a week so had a pacemaker check this evening it showed 40 diff af alerts in 7 days given antibiotics should i be worried?

Atrial fibrillation: What kind of antibiotics you are taking? A little-known fact is macrolides (clarithromycin and Erythromycin and azithromycin) can increase the risk for serious irregular heart rhythms and sudden cardiac death. In the nejm study, researchers analyzed data from more than 500, 000 medicaid patients. Patients who took Azithromycin and levoquin were at risk. Consult your physician.
