Thank you for the query.
Such symptoms can be caused by heart attack
and this is the first thing that should be ruled out. Heart ECG and heart necrosis enzymes should be checked. Her blood pressure, heart rate
and sugar level should be also checked.
More frequent and less serious reason of such symptoms is blood pressure drop due to ortostatic reaction (fast stand up for example), heart arrhytmia or due to mitral valve prolapse
. This conditions needs to be diagnosed by cardiologist. Some tests should be performed starting with 24 hours ECG, heart ultrasound
, tillt test.
can also occur in such way, that is why, she should have pregnancy test performed. Thyroid tests should be done as well.
Hope this will help.
