Thanks for posting your query.
Your wife is suffering from palpitations with normal blood pressure and increased pulse rate.
Palpitations may be due to heart or other than heart etiology.
Heart causes may be arrhythmias, mitral valve prolapse
and atrial thrombus
Arrhythmias may be Atrial Premature Contractures , Ventricular Premature Contractures, Ventricular bigeminy/ trigeminy, atrial fibrillation/ flutter.
You should consult with physician/ cardiologist and should go for ECG and 2 D echo on preliminary basis.
If your ECG is normal or inconclusive then you should go for electro-physiological studies of heart.
Other causes may be hormonal causes such as hyperthyroidism
and cushing's syndrome with excess of adrenaline hormone.
She should also go for following blood investigations: complete blood count
, serum electrolytes, thyroid profile, serum ACTH, renal function test, ECG,2 D echo.
You should also consult with neurologist
for headache and should go for CT/ MRI scan brain.
There may also be possibility of persistence of migraine along with palpitations as Betacap is effective in both cases.
