What Causes Fluttering, Palpitations And Dizziness?

Hi about one week ago I was standing in the kitchen and started having these palputations and my body shaking with dizziness it lasted for about Half an hr. that night I felt palputations all night and on Sunday for a little more.
I currently have just constant flutters with some dizziness. The doctor thinks that my body is used to taking lexapro which I have been for 3 years and never experienced this
I have been taking 5ml every three days for the last 1 1/2 years.
The doctor has told me to increase the frequency as this may stop the fluttering.
Not sure what to do
Thanks

Hello!

Thank you for asking on HCM!

I understand your concern, and would explain that the first thing to do in this situation is to exclude a possible cardiac arrythmia.

Lexapro chronic use can lead to ECG changes , which can induce a cardiac arrhythmia.

From the other hand, anxiety (related to a lower dose than needed of lexapro) may mimic this clinical scenario.

I recommend performing :
- a resting ECG
- a chest x ray study
- thyroid hormone levels
- blood electrolytes.

An ambulatory 24-48 hours monitoring may be necessary to exclude a possible cardiac arrhythmia.

If all the above tests result normal, I recommend following your doctors advise to increase the frequency and dose of lexapro.

Hope to have been helpful!

Best wishes,

Dr. Iliri
