A (Age: 64, Unit: Unknown) female patient received BNT162B2 first dose on 14Jan2021 at single dose for covid-19 immunization. Medical history included thyroidectomy and concomitant medications were not reported.

Information on the Batch/Lot number has been requested.; Sender's Comments: Based on available information, a possible contributory role of the subject product, BNT162B2 vaccine, cannot be excluded for the reported events of tachycardia, premature ventricular contractions and abnormal pulse  due to temporal relationship. There is limited information provided in this report.  Additional information is needed to better assess the case, including complete medical history, diagnostics including EKG at baseline and during subject drug therapy, echocardiogram, cardiac enzymes, electrolytes, chemistry panel and serum toxicology screen, counteractive treatment measures and concomitant medications.  This case will be reassessed once additional information is available.
