Tachycardia, covid vaccines

Although the medical and scientific community has been rather slow to recognize it, the potential connection (“signal”) between covid vaccines and tachycardia has been seen in the CDC’s VAERS data since December 2020. Tachycardia may be one of the most commonly reported “internal” (as opposed to rash, arm pain) side effects from covid vaccines.

Here is a pie chart showing reports of tachycardia in VAERS. We see fairly consistent numbers from 1990 until 2019. Then in 2020 there is a small surge, followed by an enormous surge in 2021.

Looking at the tachycardia reports from month to month, we see a gigantic surge in December 2020. Prior to this date, there were almost no reports of tachycardia on a monthly basis.

If we line up the graph of VAERS tachycardia reports and covid vaccine doses, we see a correspondence:

One question which is more challenging to assess in VAERS is whether post-covid vaccine tachycardia lasts, and for how long. Unfortunately, VAERS does not capture this data. It does, however, have data on whether or not the tachycardia had subsided by the time the report was made. We can see that half of people reporting tachycardia indicated that they had not recovered by the time their report was submitted to VAERS (there is missing data in 25% of reports). The large number of reports indicating ongoing symptoms may indicate that long-lasting tachycardia after covid vaccination.
