Can albuterol inhaler cause v tach with chronic atrial fibrillation?

Can albuterol inhaler cause v tach with chronic atrial fibrillation?

Unlikely: Albuterol can increase your atrio-ventricular conduction and make your atrial fibrillation conduct faster to the ventricles, so you could have an overall faster heart rate. Albuterol does not usually cause ventricular tachycardia or fibrillation. ...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

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

What is worse: ventricular fibrillation or atrial fibrillation?

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

Can beta blocker prevent vF or sudden cardiac arrest?

Can beta blocker prevent vF or sudden cardiac arrest?

Yes: Beta blockers are commonly used to decrease the frequency and severity of ventricular arrhythmias. Depending on your situation (state of your heart, e.t.c.), more testing, different medication, or even a defibrillator may be needed. ...Read more

Can atrial fibrillation affect ed?

Can atrial fibrillation affect ed?

Maybe: Afib can be a symptom of multiple medical problems that can affect sexual function. Metoprolol and other beta-blockers are common medications for afib that have negative impact on erections. ...Read more

Heart palpitations and dizziness. Ekg showed- shortened pr interval, and high lateral/lateral repolorization disturbance?

Heart palpitations and dizziness. Ekg showed- shortened pr interval, and high lateral/lateral repolorization disturbance?

R/O LGL Syndrome: The association of tachycardia and a short pr interval on an ekg may indicate an abnormal electrical pathway in the heart that can cause frequent palpitations and a sustained rapid heart rate. There are two syndromes called wolf-parkinson-white(wpw) and lown-ganong- levine(lgl) that are associated with short pr and tachycardia . Medication or ablation can prevent the palpitations and tachycardia. ...Read more

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

How much rate atrial fibrillation with slow ventricular ?

Usually < 60-70: Most people, left untreated, have rates between 70 and 150. It's a bit unusual to fall below that without drugs or other treatment. ...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

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

Can atrial fibrillation cause ed?

Can atrial fibrillation cause ed?

No: Afib cannot directly cause ed. Medicines used to treat afib can impair erections and conditions associated with afib such as heart failure, coronary disease also can cause ed. ...Read more

How does atrial fibrillation with ventricular standstill differ from fine v-fib?

AF vs vf: Good question, they could look alike on ECG. Both would also result in cardiac arrest. As no perfusion would result, one would expect AF waves to be less visible than VF very quickly. If arrest had been present for say more than 30sec. , VF would be more likely as the AF waves should likely not be visible. ...Read more

New onset Cardiomyopathy. Risk for Sudden Cardiac Death and Ventricular Tachycardia.....?

New onset Cardiomyopathy.  Risk for Sudden Cardiac Death and Ventricular Tachycardia.....?

Bridging the waiting period with a Wearable Defibrillator Vest: Is a wearable defibrillator (WCD) is indicated after diagnosis of NICM, but before criteria for an ICD are met? It is a common scenario. Criteria for an ICD in patients with new NICM require waiting to assess the EF response to treatment (1). In one abstract appropriate shocks were delivered in 7% of pts with an initial diagnosis of NICM (2) -- higher than might have been predicted, as an ICD study in similar pts found a rate of SCD of 1% per year (2). The level of evidence (3) for use of the WCD during the waiting period is low (4) but the stakes may be high. We need more data and professional guidelines.
