I am a 47yo female, non-smoker. average weight (5 2 @105lbs). Received an Electrocardiogram as a baseline heart test for a drug (prucalopride) that my gastrointerolgist wanted to put me on (says I d be on it probably for life and it has potential to damage my heart, thus he wanted a quick ecg to check for anything baseline to monitor). Anyway, by ECG report came back as: sinus rhythm 83bpm. (not worried about this as it seems in the normal range ) and also as low limb voltages . What does this mean and should I receive further investigations? Stuff I ve looked up online so far has me a bit worried, but not sure if I should be or not...???
