Arrhythmia

What is Arrhythmia?

Cardiac arrhythmia, also known as cardiac dysrhythmia or irregular heartbeat, is a group of conditions in which the heartbeat is irregular, too fast, or too slow. A heartbeat that is too fast - above 100 beats per minute in adults - is called tachycardia and a heartbeat that is too slow - below 60 beats per minute - is called bradycardia. --> When symptoms are present these may include palpitations or feeling a pause between heartbeats. More seriously there may be lightheadedness, passing out, shortness of breath, or chest pain. Others may result in cardiac arrest.

There are four main types of arrhythmias: extra beats, supraventricular tachycardias, ventricular arrhythmias, and bradyarrhythmias. Extra beats include premature atrial contractions and premature ventricular contractions. Supraventricular tachycardias include atrial fibrillation, atrial flutter, and paroxysmal supraventricular tachycardia. Ventricular arrhymias include ventricular fibrillation and ventricular tachycardia. Arrhythmias may occur in children; however, the normal range for the heart rate is different and depends on age. A number of tests can help with diagnosis including an electrocardiogram (ECG) and holter monitor.

Most arrhythmias can be effectively treated. Treatments may include medications, medical procedures such as a pacemaker, and surgery. Medications for a fast heart rate may include beta blockers or agents that attempt to restore a normal heart rhythm such as procainamide. This later group may have more significant side effects especially if taken for a long period of time. Pacemakers are often used for slow heart rates. Those with an irregular heartbeat are often treated with blood thinners to reduce the risk of complications. Those who have severe symptoms from an arrhythmia may be treated emergently with a jolt of electricity in the form of cardioversion or defibrillation.

Arrhythmias affect millions of people. Arrhythmias may occur at any age but are more common among older people.

Questions and answers on "Arrhythmia"

I am a 56 year, old post menopausal female who was diagnosed 18 months ago with idiopathic RVOT. My angiogram, MRI, ultrasound and other tests showed that there are no structural problems with my heart. I am very fit, eat a healthy diet, drink moderately and do not smoke. My arrhythmia is brought on by exercise and sometimes in recovery. My heart rate can shoot up to 235 but usually comes down again within 30 seconds if I cease all activity. I wear a heart rate monitor whilst exercising to keep an eye on it. When my heart rate increases I can feel a flutter in my chest and I feel, light-headed and a little detached. I had an attempted ablation around 9 months ago but it was unsuccessful as the arrhythmia did not occur during the procedure.

Recently the arrhythmia has happened more frequently. Today it happened when I was doing minimal exercise (gentle walking). Previously I would have had to be doing fairly strenuous exercise before it occurred. This is causing me difficulties as I exercise daily and I do not want to give this up.

This week I attended “Accident and Emergency” as I was feeling very light-headed at rest. My ECG was normal but I have been diagnosed with anaemia due to slight iron deficiency. I was surprised by this as I have a varied and healthy diet. There was also no blood in my stool and I do not know how I could be losing any blood. I am now taking iron tablets.

1.     What are other causes of anaemia?
2.     I understand that anaemia can cause an arrhythmia, could this in any way be linked to the RVOT?
3.     If I am now taking iron supplements can you give any estimate of how long before the anaemia is controlled?
4.     What factors might contribute to the arrhythmia happening more frequently?
5.     What are the risks/prognosis for RVOT?
6.     Is there anything I can do to minimise these risks?

Hello,

Your symptoms are indicative of developing Atrial Fibrillation or atrial flutter.

In order to be on the safer side you are suggested to go through investigations (Holter monitor, stress test, lipid profile, other investigations if required) as AF causes quivering heart beat that may cause...

Hi over the last few months my ten year old daughter has been having palpitations and fast pounding heart and chest pain and aldo feels faint with it we have been in and out of hospital with it and has shown some normal ecgs and some arrhythmia signs but we keptggetting sent home.

doctor1 MD

hello. your concern is well understood
palpitation, chest pain, faintness may be normally seen in young children. but many of the congenital heart defects also present in a similar fashion.
-since the ECG is normal- an echocardiogram should be done to exclude any heart disease.

I have benign arrhythmia. I also have a very "acidy" stomach and am prone to have gas. Not heartburn problems, just mostly lots of big burps. When I'm having an episode of gas I seem to have episodes of arrhythmia. Is there any connection between acid/gas problems and arrhythmia.

doctor1 MD

Hi and thanks for the query.

Frequent burping can be
1) Supradiaphragmatic where one just brings out swallowed air and this the commonest cause of belching
2) Infradiaphragmatic where there is expulsion of gastric contents, this is less common than supradiaphragmatic and is usually due to an...

When I smoke weed my heartbeats so fast I can feel the chambers contract but it has only happened the past two times and prior to that I had a heart murmur or arrhythmia during a lacrosse game and now when I do day to day activities my heart beats abnormally fast. What's happening to me?

Hello, Smoking of weed itself can increase the hormones like adrenaline and cortisol in the circulation causing heart to pump more faster and harder . Also in some patients it can trigger of anxiety attacks causing the symptoms you describe. So refraining from smoking should be the ideal way out...

I would like to first stop off by saying that i am uninsured.
I am 21 year old male and all of this started about 2 months about ago
I would also like to add that i am a recovering Alcoholic.
As of recently i have started having heart palpatations that occur during running walking it feels almost as if my heart is fluttering and i am dizzy and lightheaded alot and very fatigued. The other day i went for a run and by the time i got back i was so dizzy and my heart was pounding so hard i thought i was going to pass out it took almost two hours for my heart rate to come down from 100 beats per minute to 75 were it usaully rest.

The other night was the weirdest tho i was just sitting watching tv when all the sudden a palpitation came on. my heart rate shot up to almost 160 beats per minute and i panicked i started to shake could barely breath and felt like i was going to faint. So i Called a Cab and went to my local ER. When i got there they were shocked at my pulse rate and took me back and did and EKG and sed that if the EKG showed an Arrhythmia they were going to put my into the Code blue section and Monitor my Condition. But just as surely as they ran the EKG my heart rate started to come down and they sed everything looked fine. They kept me anyway for about two hours gave me some medication and fluids tho an IV ran some blood and urine test and a CT/Scan and sent me home.

I have also noticed that during mild phisical activity such as walking i start to feel dizzy and lightheaded.
And after phisical activity my heartrate rest at 110 beats a minute for almost an hour.

Ever sense then tho ive been increasingly dizzy and fainty feeling. i dont have the money or the insurance to see a cardeologest and im quite scared. It has sense started to happen to me even while im laying down trying to sleep.

Any input is greatly appreciated.

Hello XXXXXXX

Thank you for your query.

From your symptoms, it is probable that you have an arrhythmia. The specific type of arrhythmia can be diagnosed only by an ECG taken during the episode of palpitations. If you have the ECGs that were taken in the ER, you should consider seeing a...

Hi, I went to my cardiologist on 4/17. He had me put on a 30 day heart monitor. And also had me do a echo stress test later on (5/2). He suspects I have some kind of arrhythmia. I get symptoms daily (about 20-50 times a day) shortness of breath, palpitations, chest pains, occasionally dizzy, almost fainted one time with too much exertion, and get very tired after I exert myself. However, the doctor stopped my monitor test after only doing it for 14 days. I was told on the phone, they have more than enough information and I can end the test early. And then, yesterday I took the echo stress test and I was told my heart looked strong and sound internally. But, my arrhythmia didn't act up until I left the hospital of the test being done. I still need a follow up with my cardiologist about both test. However, what does it mean when they stop the 30 day heart monitor half way through?? Did it mean he found something?? Or what kind of arrhythmia would cause all these symptoms?? Thank you!

Hi friend,
Welcome to Health Care Magic

     Standard ECG records the electrical activity of the heart, for a few seconds. It can detect the arrhythmia occurring during that time only. Generally a Holter may suffice – it records continuously for 24 to 48 hours... If the episode is rare, occurs...

Hello, I had an abnormal ECG-ST & T segment downsloping in 2-3 aVF, V4-V-6. The doctor said it looked worse than the one I had 6 monthes prior. So, I was sent for an Echo Stress test- Results: Excellent exercise capacity 13.9 METS- QRS pattern in lead V1-V-2. Approximately 1-1.5 further inferolateral ST depression over the resting abnormality. No arrhythmia. It stated Otherwise, normal echo. No indication of exercise induced ischemia, or septal infarction. I worry about this everyday. Should I have further testing, my cardiologist said to see him again in 2 years. F-49 yrs. Thank-you.

Hi...My relative had intense coughing and sputum in his blood 6 months back.He got admitted....got x rays blood reports Pleural Effusion test CT Scan,Pet Scan, , and finally needle biopsy left lung......in that order. Only test positive was pleural effusion for TB,rest all were negative. For Biopsies, got slides analyzed from 3 places.....no cancer etc. So doctor advised to continue with TB treatment.All the while in last 6 months arrhythmia was there....not severe...but was there. Since last couple of weeks hs is experiencing vertigo(guess due to arrhythmia). Anyways TB follow up was due, so got all the blood/urine reports. All normal. Got Chest Ct Scan which did not show any improvment in white spot on the lung. Almost Same size etc.No growth in spot size though.

So Question is? What is causing arrhythmia ? Biopsy was done very close to heart.Also the CT scan shows no improvement yet? Major concern is Arrhythmia which is affecting mental state of patient?

Mom is 90 years old, hospitalized for heart attack May 26. She is now taking digoxin .125 mg, enalapril 5 mg, furosemide 20 mg, metoprolol 12.5 mg, potassium 20 meq, synthroid 88 mcg. Her blood pressure and heart rate is so low that her home machine won't register it. Took bp at grocery store: Wednesday 91/33, heart rate 71; Thursday 69/34, heart rate 0. Checked heart rate at home on finger device: 70-74. She also has arrhythmia (ongoing before heart attack). She feels terrible, very low energy, no appetite, diarrhea. Research on meds indicate conflicts e.g. furosemide and digoxin; enalapril and furosemide. What is your opinion of this med cocktail?
