This week I have palpitations with great weakness especially upon waking?
It’s hard to answer when you have not any information.
Are you taking heart medications or blood pressure?
If so you have them a change in your medication recently?
Do you have other symptoms that those mentioned?
do you have palpitations at other times of the day or after exercise?
I suggest you go to the hospital.
without laughing, it’s not trivial at all. My fiance had palpitations, it had intensified and he died a month ago at age 60 of a heart attack. see the doctor as soon and even more specialists
