Can Metocard ZK increase arrhythmia?

Metocard ZK, being a beta-blocker, is often used to treat arrhythmias such as tachycardia (heart beat too fast) or atrial fibrillation. It works by blocking beta-adrenergic receptors, which reduces the rate and strength of heart contraction, stabilizing the heart rhythm. However, as with any medication, there is a potential risk of side effects, including exacerbation of arrhythmias. This may be rare (occurs in approximately 7% of patients). The greatest risk occurs in the elderly and with concomitant electrolyte disturbances. If you have any concerns about the side effects of the drug, it is important to consult your doctor. If you are unable to get to your doctor, the GdziePoLek.pl service also allows you to obtain a teleconsultation with a doctor: https://www.gdziepolek.pl/telekonsultacja I encourage you to report an adverse reaction if it has not been done yet: https://www.gdziepolek.pl/artykuly/jak-i-dlaczego-zglaszac-dzialania-niepozadane
