Marijuana And Atrial Fibrillation
Heart and lung: Heart and lung work together, some people develop cardiac asthma if their heart muscle is weak. If asthma existed before the heart issues, they are treated independently. Some heart medications, such as beta blockers, can worsen asthma, some don't. It is a complex issue and needs to be discussed with your doctor. ...Read moreSee 1 more doctor answer
Can a paroxysmal atrial fibrillation and av node reentry tachycardia increase the risk for a heart attack?
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 moreSee 2 more doctor answers
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
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
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
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
Afib: Afib is the most common heart rhythm disturbance that we treat as cardiologists and can occur in a number of clinical settings and in association with other diseases both cardiac and non-cardiac. Non-valvular atrial fibrillation refers to atrial fibrillation that does not occur in the setting of mitral valve disease such as mitral stenosis or mitral regurgitation. ...Read moreSee 1 more doctor answer
Would echo,ekg,stress test,xray,bloodwork rule out any arrhythmia problem such as premature ventricular contraction and paroxysmal atrial fibrillation?
No: Occasional PVCs are normal. Paroxysmal atrial fibrillation by definition is only present some of the time and the tests you list could easily miss this if done while the heart is in normal rhythm. Diagnosis of intermittent arrhythmias can be difficult and frequently requires consultation with a cardiologist subspecialized in electrophysiology, Holter monitor test is frequently used. ...Read moreSee 1 more doctor answer
Does atrial fibrillation with pR 70_79 with no symptoms and paroxysmal attacks cause dangerousness and is anticoagulant superior to antiplatlet?
If you have no other: risk factors for thromboembolic events, then at your age, ASA (platelet inhibitor) is the recommended thromboembolic risk reducer. If you have a CHADSVASC score of greater than or equal to 2 you should be fully anticoagulated. Your health care provider should be able to advise you appropriately in this regard. Make an appointment to discuss it. ...Read more
Standstill: The extremely rapid rates of atrial fibrillation are in fact so fast that they create two problems: the top chamber is not mechanically moving very far at all, so it cannot shake clots loose, and the overactive atrial tissue secretes chemicals which increase the likelihood of clot formation. These processes come together to substantially increase stroke risk. ...Read moreSee 1 more doctor answer
