hiii dear
palpitation, tachicardia, sweating, rapid breathing,
chest pain,, all are the symptoms of anxiety
no any test reveals this
so no further test is necessary
u consulted cardiologist and he had done reports which are normal
that means you dont have heart related pathology
this is anxiety which mimic the symptoms like heart problems
so 1st accept this
2nd try to understand problem and stress factor
anxiety and
depression both have these symptoms and u have family history also
so
consult psychiatrist and get his advise
tab
etizolam is control your anxiety and escitalopram is useful for depressive symptoms if u have
do meditation
deep breathing
progressive muscle relaxation
identify stress trigger events and try to modifies it
proper sleep and diet
regular exercise
all of this help to control daily stress and anxiety
