If the panic does not improve, you should go to the hospital for an electrocardiogram to clarify whether there is an arrhythmia. Patients with hypertension, coronary artery disease and cardiac insufficiency may be triggered to have an arrhythmia after drinking cola, and in this case, an electrocardiogram should be done to clarify which type of arrhythmia it is and give the appropriate treatment.
