Important: VAERS reports alone cannot determine if a vaccine caused an adverse event. Reports may contain incomplete, inaccurate, or unverified information. Correlation does not equal causation.

About Arrhythmia Reports
Arrhythmia has been reported 2,144 times in VAERS from 1990 to 2026.
Of these reports, 137 were associated with death (6.39%) and 553 involved hospitalization.
The overall serious outcome rate (death or hospitalization) for reports mentioning Arrhythmia is 32.2%.
Understanding Arrhythmia in VAERS
•Temporal association only: These reports show Arrhythmia occurred after vaccination, not necessarily because of vaccination.
•Background rates matter: Many symptoms occur naturally at baseline rates in the population, unrelated to vaccination.
•Reporting variability: Medical terminology may be used differently by various healthcare providers and over time.
•Investigation needed: High-frequency reports may trigger further epidemiological studies to determine causation.
What This Data Shows
Most Associated Vaccines: The vaccines most frequently mentioned in reports with Arrhythmia. This may reflect usage patterns, not causation.
Severity Patterns: The percentage of reports that involve serious outcomes can help prioritize safety investigations.
Reporting Trends: Changes in reporting frequency over time may reflect increased awareness, media attention, or actual safety signals.
