Hi friend, Welcome to Health Care Magic It is not clear - what is meant by ‘strong heart beat’? If the volume is high, it can raise the systolic (upper figure)...How does he judge it? Anxiety leads to outpouring of adrenaline – which can raise the pressure... Some drugs like beta blockers have direct (intended) effects on both anxiety and pressure / In other drugs, the pressure may vary depending on the nature of the drug – there are several classes of drugs for anxiety and several drugs in each class...one can’t generalise This level of pressure is high for the age and cannot be simply attributed to anxiety and/or strong beats... / Blood pressure is a silent but steady and severe disease; but is manageable – it needs treatment. In view of the young age, he needs a battery of investigations – to search for a curable cause... He should see a cardiologist... Take care Wishing speedy recovery God bless Good luck
