Hi, thanks for using healthcare magic
Palpitations/ abnormal heart beat
can be due to an abnormal rate or rhythm of the heart.The heart may beat at a faster rate (tachycardia) or slower rate (bradycardia
) or the rhythm can be altered.
Palpitations can be due to (1) anemia (2) abnormal levels of thyroid hormone (3) side effect of medication (4) heart failure
, abnormality of the mitral valves, other heart disease
, some lung diseases (5) infections and fever can temporarily cause an elevated heart rate (6) anxiety- this is only considered when everything else has been ruled out
Investigations would involve blood tests to check your thyroid hormone level and blood count. Other investigations include an ECG to assess the rhythm and in some persons a holter (a 24 hr ECG)
You may want to consider visiting your doctor for an assessment if the symptoms continue or worsen.
I hope this helps
