EKG/ECG is at times a highly deceptive test, sometimes the process of myocardial infarction
is going on and the EKG/ECG is normal.
In any case of chest pain
, the patient should be hospitalized and ACS protocol is to be carried out viz, cardiac baseline enzyme tests including tropinin and trop T,CKMB AND ISOKET is to be started. In case of any change in the tropinin or tropT is positive standby for streptokinase or SK should be instituted.
In some of the cases Ecg/Ekg changes occur after 24 to 48 hours,i.e when the job is done.
Kindly see a good cardiologist or report to ER (cardiac) or call your help line.
