<s>[INST] HI,my husband gets shocks in his chest, sometimes three in a row, and they come very randomly. Sometimes he won't feel them for a month, sometimes longer. He is 32years old, and I am very scared because his father died young of heart issues. What does this mean, and what should I do? [/INST] He may be having PVCs. With premature hx of CAD in family he should be checked with EKG, T/t, 2D Echo and for lipid test, if these tests are normal, he may lead normal life and spend more happy time with you. </s>
