Where Is Digoxin Held Before Cardioversion
It is a heart drug...A purified product of the foxglove plant. It has effects which include strengthening the contraction of the heart muscle, slowing conduction of the heart's electrical impulse through the av node and thereby helping to slow the heart rate during atrial fibrillation. Because of potential toxicity, its use has been largely replaced ...Read more
Cardio version: Before cardio version we generally try to slow a rapid supra ventricular rhythm. Digoxin is one of the drugs we may choose to do this. It helps slow the rate by slowing conduction of impulses in the heart. We use other drugs also, so it's doctors choice which agent the believe is best for the situation. ...Read moreSee 1 more doctor answer
In the 24hrs before a heart catheter I was given 7catapress, 2lopressor, lisinoprill, lasix, (furosemide) potassium, could this induce vfib?
When serelaxin gets fda approval can this cardiovascular prescription be used as a preventative front line defense before any heart failure event takes place?
Defibrillation: Actually, we don't defibrillate when a patient is flat-lined. That is a tv thing. We can only use the defribrillator, when someone is in ventricular fibrillation (vf), thus the term, defibrillation. Vf is an abnormal rhythm, and is not resulting in a pulse, so there is no blood pressure. When a person has asystole, or a flatline, we use chemicals like Atropine to try and get the heart to start. ...Read more
Why would the implantable cardioverter-defibrillator not start a pacemaker when the pacemaker shut off?
???: I think there may be some confusion. An implanted cardio-verter defibrillator delivers a shock when certain rhythms are detected per the parameters or threshholds set by the cardiologist. The pacemaker paces the heart - the pacemaker would only 'shut off' if it was end of life, i.e. Expired battery. The icd is a pacemaker and a defibrillator and they serve two functions, both tied to heart rhythm. ...Read moreSee 1 more doctor answer
How many times is a person generally shocked or defibrillated before the doctors determine it isn't working?
How many seconds is the length of the pause categorized dangerous and must wear a pacemaker?? sometimes i was pause when my heart fibrilation.
ACCF recommendations: Generally, if there is a sustained P wave duration (long first beat) of more than 120msec, atrial pacing is recommended in this situation. But the American College of Cardiology Foundation recommends that permanent pacing is not recommended to prevent Afib in the absence of another indication for a pacemaker, but does recommend one for patients with Afib and slow heart rate ( ...Read more
Before suctioning an intubated patient hooked to mechanical ventilator, is it right to increase the fio2 to 100% to hyperoxygenate the patient?
Usually: That is usually the norm because, you are technically suctioning out air (and thus oxygen) from the lung when you suction. In all reality, does it affect oxygenation that much? Probably not. But, turning up the oxygen to 100% for a few seconds usually causes no harm. ...Read moreSee 1 more doctor answer
Just found out the insulin taken when necessary is the shorter acting version. When is the longer acting version prescribed to a patient. Helpful?
Insulin: At your age you are most likely to have diabetes without your pancreas making enough insulin. What dose of insulin are you taking? How often are you checking your blood sugar? Are you taking any non-insulin medications for diabetes? If you can please let me know the answers to these questions. ...Read more
Is a transeptal puncture required to access the left ventricular during an EP study for ventricular tachycardia? If so, is it as risky as A-fib?
If the tachycardia: is originating from a left sided focus either transeptal approach or retrograde approach across the aortic valve would be necessary. Any time you are intervening on the left side there are slightly increased risks but in experienced hands this is no more concerning than any other interventional procedure. ...Read more
If atrial fibrillation, after aortic valve replacement (in female 79), how is this usually corrected? Bisoprolol, metoprolol , sotalol already tried.
Cardioversion?: Initially with rate control and anti-coagulation. If the atrial fibrillation is causing you symptoms, then a controlled and timed shock to the heart, called cardioversion, can be administrated tito regulate your heart. This is an outpatient procedure. Discuss with your doctor. ...Read moreSee 1 more doctor answer
Let me help myou: Digoxin is a heart stimulant with a very narrow range of safe doses. Ventricular tachycardia is very common adverse side effect of digoxin, and would likely make this condition worse or increase the frequency of the episodes. Stimulating a heart that is already beating too fast (tachycardia) could be fatal. Good luck. ...Read moreSee 1 more doctor answer
