### Human:\nheart rhythm disorder. my discharge papers says to get help if: you notice a change in speed rhythm or strength of your heartbeat. you suddenly begin peeing (urinating) more often. you get tired more easily when moving or exercising. i had my meds changed for this to a stronger mg on wednesday. today is friday. i am having rapid fluttering heartbeat and am peeing more often and lots more each time. should i be worried?\n\n### Assistant: better visit your consultant. the change of medication to stronger dosage must have caused these side effects. your doctor will check and advise to change them.
