No, theese are not signs of a
heart attack. Keep calm about this.
The heart attack has sudden onset, intense
chest pain like a bunning pain, accompanied by nausea,
vomiting,
profuse sweating... Theese makes everyone go the emergency room immediately.
Headache could be related to stress, related about your emotional state. The most comon kind of headache is the tensional headache.
When you're stressed a hormone called epinefrin is released in your blood. It's effect accelerate your heart beat and this is the most likely cause of the palpitations that you reported. These hormone works only for a few minutes, so if your stress goes away, the epinefrin effects goes away too.
I suggest my patients the following:
1- When the palpitations came, seat down and relax for 20 minutes.
2- Try ioga to relax.
3- Look for a early consultation with a
Neurologist to confirm the real cause of the headache and prescribe de best treatment.
4- Look for a Cardiologist to ward off unusual rhythm disorders as a cause of palpitations.
