Hi, thanks for writing to HCM.
In my opinion, there is no relationship between usage of statins and palpitations /irregular heart beats.
The most common side effect of statins is SKELETAL muscle pain (Cardiac muscle
is SMOOTH muscle
). Very rarely, statins can cause life threatening muscle damage called RHABDOMYOLYSIS
which can cause Liver, Kidney damage and death at death rarely.
Early complications of rhabdomyolysis include very high levels of Potassium in the blood which can lead to irregular heart beat or cardiac arrest
Consult your treating physician and discuss all the issues.
Hope this information is helpful. Good day
