Get yourself clinically examined and investigated.

Detailed Answer:
Hi,
Thanks for writing your query.

After reading your post, I would like to advise that you should get yourself clinically examined and investigated. Your symptoms can be due to anxiety but a thorough clinical evaluation will help.

Following investigations may be helpful :-
1. Hemoglobin levels.
2. ECG.
3. 2D Echo of heart.
4. Thyroid profile.
5. Blood pressure and heart rate monitoring.

More can be commented after knowing the reports of the above mentioned investigations and according to the clinical evaluation done by your doctor.

I hope this is helpful to you.
If you have any further query, I will be happy to help.
Thanks.

Hey, I was diagnosed with an eating disorder and the effects were secondary amenorrhea and bradycardia. My resting rate rate then was 45 and they said it could be reversed but I was wondering if it was possible to reverse it in a week? I ve been following their orders of eating more for about 5 days now and my resting heart rate is between 70-80 every time I check it.

My resting heart rate is unusually fast and even if i just walk up the stairs my heart is racing like ive just ran a mile. When i exercise i can feel my heartbeat in my chin and other strange places aswell as having red, blotchy skin all over my body, mostly my face and arms. Also, after exercise, if i open my mouth i can hear my heartbeat, its like a ticking noise. My mouth goes very very dry too. Finally ive noticed that if i lie down and place something across my chest for example a book or ipad, i can see my ipad wobble alot from my heartbeat, is any of this normal??

My rest heart rate is typically around 100 and my blood pressure is typically very good. I am now taking Bisoprol 5mg for atrial tachycardia. My last read had my rest heart rate at 94 but my blood pressure has dropped to 101/57. Should I be concerned?

I am a 23 year old female, studying medicine. For past 8 months, i have been having some episodes of heart 'dysfunctions' that now have turned constant. I need help in knowing what is the condition.
It started last may when one day i started feeling so weak that i just could not get up and was having a splitting headache, when i measured my BP was 90/55mmHg ( before it was always 120/80mmHg). I was having palpitations, bradycardia at times, tachycardia at times, extreme weakness, sweating ( especially on scalp) after sleeping after headache. I was also having light sleep.
Slowly, these episodes became constant. Now I am feeling weak all times, light headed if sitting or standing for long, headache (thumping with constant heaviness), inability to sleep, tightness in chest, chest pain sometimes, tachycardia at any normal activity (walking, doing some tidy up), BP is still low. I also get dry cough on breathing sometimes.
So i got a holter done for 24 hours, got following:
- sinus tachycardia( 110- 120) almost all day with some normal rate in between, my heart rate dropped to 50 in middle of night ( reason causing me to wake up from sleep and not to sleep again) and it remained like that for 3 hours
- average pulse -81
- my heart rate jumped to 179 per min when i climbed stairs ( 9 floors, easily climbed by others), breathing became laboured, headache with blacking out sensations ( i did not faint though)
- I have some abnormalities in lead I, II and III ( looks like left axis deviation as lead I is showing highest peaks and is moving away from III ) even the avL and avF looks weird, QTc>450ms is 47%, no ST deviation, no T wave abnormalities
I also have tachypnea (26-28 per min) and accentuation of Pulmonary part of second heart sound. I also have slight edema on my feet ( bluish tinge)
I also did a blood work up, I do not have thyroid problems or anemia
I need some advice on what i might be having, so as to proceed further on treatment.
