My ECG says Sinus Bradycardia with premature atrial complexes?

my vent rate was 56 pr interval was 156 QRS duration was 84 ms QT/QTc was 402/387 ms and my P-R-T axes were 71 71 47 what does this all mean?? I had an allergic reaction to a medication 2 days before this was taken. and almost 1 week later still having a hard time breathing??

How can u say if a person was born premature if that person behaves as normal as others do.
What are the signs?

Most babies that are born premature grow up to be completely normal. They are not abnormal. Premature means that the baby was born before 38-40 weeks of gestation. Only VERY premature babies may grow up with certain problems, such as brain damage.
The vast majority of people who were born before 40 weeks of gestation turn out just fine.  (+ info)

my daughter was diagnosed w/ Sinus Rhythm w/ blocked Premature Atrial Complexes...?

can anyone give me more information on what this actually means...our daughter explained it to us...but i was so out of the loop cuz of the shock that i dont recall half of what info he gave us. please inform. thank you in advance.
sorry...meant to say our DOCTOR explained it to us.
Attn: Robbert Hobbemeister

Our daughter is 5 yrs old, and we first became aware of this when we noticed a slight difference in her heart beat.

I wish we could ask a question, and then answer again, but here goes -

I'm guessing the doctor said she had a sinus rhythm with non-conducting PACs - that means that her sinus node in her heart is firing off an electric charge before it should, by a matter of 10ths of a second. But, it is just an electrical discharge, the heart is not actually beating. Which is good, because that means the atria is getting enough time to fully fill before it pumps the blood down to the ventrical. 30% of the heart's pumping power comes from filling up before it pumps, like a rubber band shoots farther is you stretch it more (starling's reflex, if you care for the name).

The premature discharge could be from an irritated spot on her heart, or a node that is misfiring. Depending on what happens with it and why will change the treatment. She could just be put on a medication to block that initial discharge. They could go in with a wire and burn off the spot that is irritated if it is a part of the heart. They may have to close a pathway if the electrical signal is coming from the ventricals backwards up to the atria.

This is the part where questions would help. Did you hear Wolfe-Parkinson's White? How old is she? How did they find out - was she sick and they did a test, or was it an incidental finding?

That's at least a very brief idea - please don't be afraid to ask the doctor lots and lots of questions - if they don't want to answer, find another doctor. It always amazes me that people don't question the MD - it is your medical care, your body. Learn as much as you can from them, never leave with a question, and never take a medication without knowing what it is and why you are (or she is ) taking it.

OK - then you noticed an irregularity. Her heart should beat 100x a minute, at a regular clip, you noticed little gaps - that means her heart discharged too early, but did not pump, and so it missed a beat. Carefully review the paperwork from the doctor, including discharge instructions. Make the appointment with the specialist if they set one up. Look online for info on the diagnosis the pediatrician thinks it might be, and have lots of questions for the cardiologist. Most importantly, don't freak out prematurely. If she behaves normally, she is doing well now. Just follow the steps as they are laid out to you.

Good luck.  (+ info)

What hospital in SF / Bay Area would you recommend to someone who may give birth to premature baby ?

Hello, my pregnant wife is expecting a baby in 3 months, but she has "notch" and the baby is not growing as fast as it should.
There is a risk that the baby might need to get born earlier than the typical 9 months.
As I am relocating in SF for work, I was wondering what is the best hospital that has the right structure to handle that kind of more complex cases.

Stanford, Oakland Childrens Hospital, UCSF  (+ info)

Which of the following correlations between cardiac contractions and ECG waves is correct? ?

A. All chambers are contracted during the period between the T wave and the next P wave.
B. Atrial diastole precedes the appearance of the QRS complex.
C. Ventricular diastole precedes the appearance of the T wave.
D. Atrial systole persists through the S-T segment.
E. Ventricular systole begins after the QRS complex appears.

How does sudden cardiac death work in teenagers?

I'm 16, I have difficulty breathing when I exercise, and I sometimes get panic attacks/dizzy spells. I'm not an athlete, so I don't play any sports. If a teenager has a heart problem, are they still at risk for sudden cardiac arrest even if they don't play a sport/heavily exercise?

Sudden Cardiac Death in teenage years is typically related to either a genetic (hereditary) disorder which predisposes you to ventricular arrhythmias (the cause of SCD), for concern for this just look back to your family history to find if anyone had died unexpectantly - and without a history of drug use - before their 30th birthdays. Typically we find a significant family history with little effort in these individuals that genetic testing is not really necessary.

A simple ultrasound (echo) can identify patients with a dilated or hypertrophic cardiomyopathy (a structural abnormality in the heart) which is the other main, typically non-genetic, cause of SCD. In the end, strict control of weight, blood pressure, and good dietary choices will help stave off eventual life-style causes of cardiomyopathies. But if there is any true concern, an echocardiogram would be highly advised for diagnosis for cardiomyopathies.  (+ info)

What causes the cardiac arrest in a bulimic?

I was wondering what actually happens when a bulimic has a cardiac arrest and why bulimia affects the heart? I know that the body doesn't receive nutrients like it should but if your bulimic and you still eat a little during the day then how is your heart failing if you eat at least a little? Does the body lose nutrients over time or suddenly?

The most dangerous health risk posed by bulimia is cardiac arrest or heart attack due to an electrolyte imbalance of the mineral potassium, read further at http://www.princeton.edu/uhs/healthy-living/hot-topics/eating-disorders/  (+ info)

What is a Double Cardiac Catheterization as opposed to a Cardiac Catheterization?

I have to have a double cardiac catheterization done on February 16. I know what a Cardiac Catheterization is, but not a Double. I thought this procedure was going to fix my heart murmur, but it's something about examining the heart to see if it's pumping correctly and everything.

The term 'Double Cardiac Catheterization' is not commonly used in medical lexicon. Based on meagre detail you provided, it may be presumed that it relates to pressure studies etc in both left and right heart.

If you know what is cardiac catheterization, you also must be knowing that approach to either side is different( unless one has a hole in the heart that allows left heart catheter to enter right heart through the hole).

a) Left heart catheterization: The procedure is done by percutaneous femoral, radial, or brachial "artery" puncture, with a catheter passed into the coronary artery ostia or across the aortic valve into the LV.

b) Right heart Cath: The procedure is done by femoral, subclavian, internal jugular, or antecubital "vein" puncture. A catheter is passed into the RA, through the tricuspid valve, into the RV, and across the pulmonary valve into the pulmonary artery.

(NOTE the double qoute marks in both (a) and (b)).

So, the doctors may be planning to study both sides of heart simultaneously using two catheters.

Or, could that be double-channel catheter :-> one with two channels, one for injection and the other for fluid removal.  (+ info)

How long after a cardiac arrest is a paitent discharged?

I know that they keep the paitent for a few days in the case of another cardiac arrest (i think), but how long does the paitent remain hospitalized afterwards?

This depends on the severity and cause.

30 years ago my father had a heart attack and was in hospital for two weeks. Someone I know recently had one but was home within 5 days with strict orders about what to do once home.

Nowadays they do prefer people to be up and about once they are on the road to recovery but it does depend on a lot of factors.  (+ info)

What cardiac exercises can I do at home?

I want to do half an hour of cardiac exercise in my home everyday. I do not have a big garden. It is only small but enough to run in small circles in. :) I would like exercises to get my heart rate up. I already have running up stairs and jogging on the spot. Thanks.

Running upstairs will do it. Even walking up them. Calisthenics (like jumping jacks) will work, too.  (+ info)
