Are premature atrial contractions dangerous?

Are premature atrial contractions dangerous?

No: There is far more concern with a completely disorganized atrial rhythm called atrial fibrillation. Occasional early beats are of no concern. ...Read more

Premature (Definition)

Very premature is a condition in which a baby is delivered between 28 and 31 weeks' gestation. Depending on how premature, how sick, and how lucky or unlucky a baby is, he can get brain problems, cerebral palsy, blindness, deafness, developmental problems, learning disabilities, severe lung diseases, infection and loss of some intestines, etc... Babies who are only moderately premature usually ...Read more

Are premature atrial contractions dangerous?

Are premature atrial contractions dangerous?

In general no: In general pacs or premature atrial contractions are benign - not harmful. They may be caused by excessive stimulants such as caffeine, nicotine, even sugar. Anxiety can also cause this - if your physician has thoroughly evaluated this and ruled out other causes this may be the issue. ...Read more

Can atrial fibrillation with rapid ventricular beat cause ventricular fibrillation?

Can atrial fibrillation with rapid ventricular beat cause ventricular fibrillation?

Not usually: Not typically; however, if you also have an accessory pathway (wolff-parkinson-white syndrome), this is a unique situation where af is known to cause very rapid ventricular activation during af, which can lead to vf. Rapid ventricular response may cause cardiac weakening over time, which in turn may increase the risk of vf. ...Read more

Heart problems ventricular bigeminy?

Heart problems ventricular bigeminy?

Usually benign: Premature or "skipped" beats frome the bottom chambers of the heart are common; they sometimes occur in fixed patterns. When every other beat is a premature beat, it's called ventricular bigeminy. When every 3rd beat is premature, it's called ventricular trigeminy, and so on. Bottom line: with a normal heart, these patterns are completely benign and don't need treatment unless very troubling. ...Read more

What are premature ventricular contractions?

See below : Premature ventricular contractions or PVCs for short are extra beats from the lower chambers of the heart - the ventricles. Symptoms include skip beats and/or palpitations. ...Read more

Slow heart rate, premature atrial contractions, are they connected?

Slow heart rate, premature atrial contractions, are they connected?

AV Block?: Yes, it is very possible that the slow rate of ventricular contractions cannot keep up with a faster atrial contraction rate. It is an a-v block. ...Read more

Does atrial fibrillation with rapid ventricular response cause ventricular fibrillation?

Does atrial fibrillation with rapid ventricular response cause ventricular fibrillation?

Only in a Very Few: Generally, the answer to this is a very solid "no." this is a rare complication of people with another condition (on top of their afib) called wolff-parkinson-white syndrome (or wpw). In certain patients having both conditions, the top chamber is too-well connected to the bottom and can trigger ventricular fibrillation. ...Read more

Are premature ventricular contraction or ectopic heartbeats dangerous to me?

Are premature ventricular contraction or ectopic heartbeats dangerous to me?

PVCs and MI: Premature ventricular contractions mean that there is irritability in the heart muscle and normal heart rhythm which starts from high up in the atria is inturrupted in some beats and those beats are originating in the ventricle.Bot it does not mean that it is directly due to mi.But you can get pvcs with mi.Occasional pvcs are not serious but if it comes from many foci and in runs it can be seriou. ...Read more

Not enough info: What distinguishes the significance of a rhythm disturbance is what the condition of the heart is, not the rhythm per se. Your mother needs an evaluation which includes information about how strong her heart is and whether she has evidence of blocked arteries. Other considerations are what meds she takes, her use of nicotine, alcohol and caffeine, and what symptoms, if any, she has. Warm wishes. ...Read more

What causes pulseless ventricular tachycardia?

What causes pulseless ventricular tachycardia?

Not really pulseless: When VT occurs at a fast enough rate, there is inadequate time for ventricular filling, cardiac output falls, and blood pressure falls. You may not be able to palpate a pulse but an arterial line would show a waveform that is reduced in amplitude. Rate is the key. As tissue perfusion fails, acidosis, hypoxemia and hyperkalemia result leading to ventricular fibrillation and death. ...Read more

Compare ventricular vs supraventricular tachycardia?

Atria or ventricles: Supra ventricular tachycardia: from upper chambers of the heart, is due to irritability (increased automaticity) or a short circuit (reentry), heart is usually structurally normal. Ventricular tachycardia: from lower chambers of the heart, due to irritability, can occur in normal hearts but is more often seen in hearts with scar tissue or weak hearts and can be life threatening. ...Read more

Why is ventricular fibrillation worse than atrial fibrillation?

Fibrillation: atrial fibrillation has normal left ventricular contractions put poor atrial function. Ventricular fibrillation has no real ventricular contractions so blood pumping essentially stops. Atrial fibrillation is a rhythm you can live with. Ventricular fibrillation is a rhythm you die with unless it is corrected quickly. ...Read more

Is an irregular heart beat usually atrial fibrillation?

Is an irregular heart beat usually atrial fibrillation?

Not always: It certainly can be. Although there are multiple instances when one can have an "irregular heartbeat'. You should see your doctor so an ekg can be done or possibly a monitoring device ordered to evaluate further. ...Read more

14 day loop results states tachycardia up to 140, bradycardia 42 bpm, ventricular ectopic complexes, supra ventricular ectopic complexes and an atrial couplet. Should I be worried?

14 day loop results states tachycardia up to 140, bradycardia 42 bpm, ventricular ectopic complexes, supra ventricular ectopic complexes and an atrial couplet. Should I be worried?

Arrhythmias: You should be talking to your doctor about the situation to get more information. The rhythms alone don't necessarily imply something 'bad'. On the other hand if you were entirely normal they wouldn't be there. The rest of your condition is what tells you whether you should be worried. Your doctor is best positioned to answer that question. ...Read more

What is more dangerous, atrial fibrillation or ventricular fibrillation?

For: Any chances to "recover" from vfib one need to be in an intensive care an hooked to an ekg. And a slim chance to live. If someone collapses on the street, help has to come in minutes to jump heart back to normal rhythm. People who go in vfib have an underlying and severe heart disease. Conclusion vfib kills a afib can be controlled, even normal rhythm may be restored. Big difference! ...Read more
