What causes weakness and breaking out in a cold sweat when you have a pacemaker?

Weakness and breaking out in a cold sweat with a pacemaker can be caused by several factors, including improper pacing due to lead displacement or malfunction, which may lead to inadequate heart function. Additionally, issues like medication side effects, low blood pressure, or underlying heart conditions can contribute to these symptoms. Stress or anxiety related to the presence of the pacemaker might also play a role. It's important to consult a healthcare professional to determine the specific cause and appropriate treatment.
