Increased Heart Rate Recently, BP Consistently Low. All Tests Normal. What Could Be The Cause ?

I am a 26yo female. I weigh 208, i am 5'4" tall. I have no daily meds. My heart rate has been increased the past few days, especially when i lay down. My bloodnpressure has been low but not consisitently. My lowest bp was 88/56;and my highest pulse was 98. I went to a minor medical facility but they didnt perform any tests like ekg, cbc,etc only bp and O2 levels and temp which was all normal. Now im lying down trying to go to sleep and my heart rate is up again. Im also on my period. Please help me

Hi friend,
Welcome to Health Care Magic

     THE FIRST STEP IS TO SEE A CARDIOLOGIST / Heart beats need to be DOCUMENTED by ElectroCardioGram (EKG). / You may need Holter or event monitor
     Anaemia / Anxiety / Alcohol / Tobacco (smoking) / Caffeine (too much tea, coffee, cola) / Fever / Infection / Pain / Stress / Thyroid / Vitamin D, calcium, magnesium / Medicines like Phenylephrine used for ‘cold’; Salbutamol used for asthma and so on - may be responsible.... / Illicit ‘drugs’ like Amphetamine are notorious to cause abnormal beats / At times, abnormal nerve paths in the heart (bypass tracts) or disease of the conduction system may be responsible!
     ECHOcardiogram / LABORATORY work-up – may all be necessary for further assessment and assistance. The treating doctor may suggest them depending on need, based on his assessment of the situation.
     The low BP may be due to higher heart rate...
     You need examination and investigation...
     You ought to go for life style changes – to educe your weight...

Take care
Wishing speedy recovery
God bless
Good luck

Considering your highest heart rate 96/min, what you call high is actually within normal limit (60-100/ min). Now , heart rate can not be constant always i.e it can not remain 70 throughout the day.
there are hundreds of causes (normal as well as abnormal) of increased heart rate .
But you dont fall into that category.
if you lowest heart rate was 60 or more and cosideering highest as 98 then its absoliutely normal, dont get panic for your heart rate.
Yes what you say fast may be - you can personally feel that your heart is beating, (usually one is not aware of heart beating).
Anxiety or any mental stress or even lack of sleep can causes it.
BP you said 88/56, i would like to know what is source of this reading, is it electronic device?? if so they are highly inaccurate many times, more so especially if you use the one at wrist.
A carefully taken manual reading is most reliable,
it is not uncommon to have BP of 90/60 as a normal reading of one,
what is the highest BP you have known.
Low BP can cause giddiness(you can even fall), darkness in front of you r eyes, feeling very weak, altered mentation etc kind of symptoms, did you experience any of them ??
You MAY opt for 24-Hrs ambulatory BP monitoring (ABP) which is a small device tied to your chest and it will automatically record BP , over 24Hrs
It will provide helpful insight
