V Fib Arrest
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
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
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
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?
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
DX neurocardiogenic syncope ECG: Left atrial enlargement,Low voltage QRS, Borderline ECG Normal sinus rhythm. Is the ECG normal?
No: Abnormal. Low voltage Left atrial enlargement . ...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
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
Paroxysmal atrial tachy, flutter. Mitral regurg w/stenosis. Tricuspid regurg. Biatrial enlargement. Cardiac meds =hypotensive brady. Explain,thoughts?
Symptoms: You should be seeing a cardiologist for evaluation and management. ...Read more
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
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.
