Calling all doctors and nurses

Okay so my bf went to the doctor today becaus he has numbness in his left pinky odd vision and fatigue. They put him on an ekg machine said the results were abnormal. But his heart rate was 92. They told him that he should go to the er but his mom said not too, she’s not a doctor or nurse. Should we be worried? He’s Dad has a heart condition and his grandfather died of a heart attack. So he does have heart issues in the family (update: I’m in South Carolina and he’s in Louisiana)
