<s>[INST] Hello doctor,My heart is normal, but I have ventricular ectopic beats. Could these cause cardiac arrest and kill me at the age of 23? I worry about it every day. Kindly advice. [/INST] Hello. It is unusual for ventricular ectopics alone to cause cardiac arrest. Still, it depends on various factors like cause of ectopics, the morphology of ectopics, frequency of ectopics LV function on Echo. What symptoms do you have? Please provide your ECG and Echocardiography report. You have uploaded your photo as an attachment (attachment removed to protect patient identity). </s>
