What makes atrial fibrillation not immediately life threatening while ventricular fibrillation is?

What makes atrial fibrillation not immediately life threatening while ventricular fibrillation is?

A circuit breaker: The rhythms in the top chamber during atrial fibrillation can reach and exceed 600 bpm. If this were conducted directly to the lower chamber, it would be as fatal as ventricular fibrillation. However, nature built in a circuit breaker called the av node between the two such that only some of the top chamber heartbeats in fibrillation make it to the bottom chamber. ...Read more

What is more dangerous, atrial fibrillation or ventricular fibrillation?

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

What is worse: ventricular fibrillation or atrial fibrillation?

Ventricular fib: Vf is worse; it usually causes cardiac arrest which is often fatal. Atrial fibrillation, while not as severe, also has significant health risks. It increases the risk of stroke, which can be disabling or fatal. Additionally, if the af causes a fast pulse for a prolonged period of time, this may lead to weakening of the heart and cause heart failure. ...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 a pulmonary embolism life threatening?

Definitely can be!: More people die each year from Pulmonary embolism (PE) than highway fatalities, breast cancer & AIDS combine. PE causes or contributes to 15% of all hospital deaths. Due to pulmonary arterial obstruction, PE can result in acute right ventricular failure, a life-threatening condition.Since most patients tend to die within the first hrs of presentation, early diagnosis & treatment can be life saving ...Read more

Is atrial fibrillation a disability?

It can be: If afib is difficult to treat ie unable to convert patient to normal rythm or unable to slow rate down with medicines, or perhapse the patient can't tolerate the medications to treat the problem , a person can be disabled. Pts with pre existing heart problems may not tolerate afib as well. Ablation therapy is not always effective and some patients may need a pacemaker. Just depends on pt ...Read more

Is calciphylaxis life threatening?

Is calciphylaxis life threatening?

Yes: Calciphylaxis is, in a way, hardening of the arterioles (very small arteries) that supply blood to the skin. The arterioles are clogged, and blood does not pass, resulting in the death of the skin supplied. It is rare, occurring primarily in people with end stage renal disease (eg on dialysis) or rarely people with hyperparathyroidism (overactive parathyroid glands). ...Read more

What is more serious, atrial or ventricular fibrilation?

Ventricular: Both are serious. However, vf is often associated with pending collapse of the circulatory system. Vf is a serious complication of acute heart attacks and other heart disease and must be treated aggressively, usually in the ICU setting. Af can be life threatening, but is often discovered incidentally and some live with it untreated. Untreated vf is usually fatal. ...Read more

What is atrial fibrillation?

Arrhythmias: Atrial fibrillation (afib) is the most common sustained rhythm abnormality. It's characterized by an irregular heart rate. The upper chambers of the heart (atrium) do not beat but quiver. Many people don't notice it. But many do. It can lead to strokes in some patients so blood thinners are important. It can be treated with medications, ablation thru iv's in the groin or surgery. See a cardiologis. ...Read more
