How does anemia cause tachycardia (increased heart rate)?

---

What is the mechanism of action in which anemia causes tachycardia?

Please explain the mechanism in detail and please state an internet source.
hii there! :) yea.. totally agree with the madam nurse up there :) if you're anaemic (low RBC count), then low or inadequate oxygen delivered to your tissues and organs, your hypoxic (lack of oxygen) tissues will send signals to your brain that it lacks oxygen and can't function properly. In response, your brain will stimulate your heart to pump faster (tachycardia) inorder to compensate for the lack of oxygen.. so there, thats why you'll be tachycardic as initial short term manifestation.. You see, oxygen is very impt for every single cell in our body inorder to carry out their functions properly.. and this oxygen is delivered via the blood.. thats why there's blood circulation in every inch of our body!! amazing right??! :)
hope i was able to answer your question.. ;p  (+ info)

What does tachycardia and low blood pressure suggest?

---

Ive been experiencing it for months but with no definitive diagnosis. Some ekg's show right atrial enlargement and high qrs wave and one echo showed trivial regurgitaion and then there was a prolapse on the second. My doctor put me on batalockers and the cardiologist told me to go to mental health for anxiety but my pulse is always like 120. What should I do?
your heart is trying very hard to push blood out but it is not filling very well so you have decreased bp which inturn is causing you to have and enlarged heart. the beta blocker will help to slow your heart down to fill better. Maybe find out if digoxin will help you heart pump more efficiently too. I don't know you personally but your doctor may have picked up on something when he suggested you get looked in on anxiety (which will cause your tachycardia/pulse 120).  (+ info)

What probable risks are attributed to untreated bradycardia or tachycardia?

---

The treatment is delayed due to non-availabilty of hospital facilities on account of prior bookings.
With Tachycardia the heart pumps less efficiently and provides less blood flow to the rest of the body, including the heart itself. It means that the person who has it could have parts of their body die, from not having enough blood flow and the cells dying from oxygen starvation.

Bradycardia on the other hand, is considered normal if the individual has no other symptoms such as fatigue, weakness, dizziness, lightheadedness, fainting, chest discomfort, palpitations or shortness of breath associated with it.

I hope that helps.  (+ info)

Somebody being young adult and healthy, can experience really tachycardia just walking for 30 seconds?

---

If your heart is aparently normal. Can you get heart arrytmias doing a very little effort ? It happens to me.
Yes, it can even in case of Coronary Artery diseases, or other CHD (Chronic Heart Disease/s). Check it out with your cardiologist.  (+ info)

Does anyone know how to treat tachycardia without medication?

---

my doctor has told me i'm going to have to quit sport because of this heart condition, and because of my asthma i am unable to take beta blockers. any natural remedies or anything like that?
What medications do you take for your asthma? Sometimes inhalers or updraft treatments can make your heart beat faster, as well as asthma itself!

How tachycardic are you? (What does your heart rate usually run??)

People with severe asthma cannot tolerate beta blockers because it can cause bronchospasm, but people with mild asthma can take a beta blocker without difficulty.

There are other medicines that can slow your heart rate such as calcium channel blockers.

Otherwise there isn't much you can do to keep your heart rate slower...execise (over time) can improve conditioning which will gradually lower your heart rate. Decreasing caffiene intake or quitting caffiene all together can decrease your heart rate. Avoiding some decongestants can help. Keeping your asthma well controlled can help.

Hope this helps some.

Is it ok to run while suffering tachycardia caused by alcohol withdrawal syndrome?

---

I'm on my second day of alcohol withdrawal and am having periodic panic attacks, nearly constant anxiety, and a rapid heart beat--which comes in waves.

I'm twenty-seven years old and otherwise healthy. Lying in bed all day has worsened the already-occurring insomnia and I feel I need to exercise.
What say you start with some yoga? Get a video from the library you don't have to buy one. Your body is going through enough right now. And seriously, ask a doctor about this. Alcohol withdrawal can be life threatening. This is not something to ask a well-meaning, but unqualified person on a site like this about.  (+ info)

If I have tachycardia but the ECG results come back normal what are the causes?

---

The ECG results were normal but my heart was going too fast. Why?
At the time my heart rate was around 130 no more.
It means your tachycardia is paroxysmal or episodic. It comes and goes and present at the time of ECG. This condition is called Paroxysmal supraventricular tachycardia(PSVT). Read on....

Paroxysmal supraventricular (atrial) tachycardia is a regular, fast (160 to 220 beats per minute) heart rate that begins and ends suddenly and originates in heart tissue other than that in the ventricles.

*Most people have uncomfortable palpitations, shortness of breath, and chest pain.
*Episodes can often be stopped by maneuvers that stimulate the vagus nerve, which slows the heart rate.
*Sometimes, people are given drugs to stop the episode.

Paroxysmal supraventricular tachycardia is most common among young people and is more unpleasant than dangerous. It may occur during vigorous exercise.Paroxysmal supraventricular tachycardia may be triggered by a premature heartbeat that repeatedly activates the heart at a fast rate.

The fast heart rate tends to begin and end suddenly and may last from a few minutes to many hours. It is almost always experienced as an uncomfortable palpitation. It is often associated with other symptoms, such as weakness, light-headedness, shortness of breath, and chest pain. Usually, the heart is otherwise normal. The doctor confirms the diagnosis by doing an electrocardiogram (ECG).

This may be induced by premature atrial or ventricular ectopic beats. Other triggers include digitalis toxicity, hyperthyroidism and stimulants, including caffeine, drugs, and alcohol.

ECG is no use here. You need 24hr Holter heart monitoring.  (+ info)

Whats between Normal and Tachycardia in a 12-15 year old?

---

I know the average is 80 the range is 60-100 but whats 101-119?
Oh, before anyone says "GO TO A DOCTOR" I dont have a heart rate like this, I just saw it somewhere and was curious.
It's high for a resting heart rate, but if the person is exercising, of course it's okay! :)  (+ info)
