Dear Mrs,
You describe elevated
heart rate, which is usually benign and can be caused by many reasons, such as stress, over-
tiredness etc.
You also describe some kind of
arrhythmia, which can be benign, if is not very frequent, and can have same causes.
If you have a stressful period, I would advise you, try to regulate your lifestyle, have a healthy sleep, and everything will normalize gradually.
If you see no improvement, I would advise you to see your doctor, to perform an ECG, and some labs, such as serum electrolytes, Hb,
thyroid tests.
Wishing you a good health
Regards,
