Atrial Fibrillation (AFib) Support Group
Atrial fibrillation (AF or afib) is an abnormal heart rhythm (cardiac arrhythmia) which involves the two small, upper heart chambers (the atria). Heart beats in a normal heart begin after electricity generated in the atria by the sinoatrial node spread through the heart and cause contraction of the heart muscle and pumping of blood.
Good luck. Oh yes. Make sure you pee immediately before the procedure (like on the way to the Cat lab). You will be flat on your back for up to many hours after they procedure as the punctures close. And, don't pop out of bed to go pee, as soon as they take the harness off your legs. I did that, and passed right out, good thing the nurse caught me before I hit the floor.
Take care and enjoy the weekend,

The diagnostic EP study will be performed by inserting hemostatic sheaths into the femoral and/or subclavian veins. Through these sheaths, long small temporary pacing catheters are passed under fluoroscopic guidance to the heart and positioned in the right atrium, near the His bundle, in the right ventricle and usually also in the coronary sinus. These catheters record activation of the heart and pacing can also be delivered to induce either tachycardias or bradycardias. In this way the heart electrical system can be assessed and arrhythmias induced. The patients arrhythmia can be induced in over 95% of the cases by putting in premature beats in either the atrium or the ventricle or by rapid burst pacing. Sometimes repeat stimulation after drugs like isoproterenol is required as well.
Next the intracardiac mapping procedure is performed. This involves moving a steerable catheter around the inside of the heart while the patient is in their arrhythmia to see where earliest activation occurs this is the origin of the arrhythmia. Sometimes three-dimensional mapping systems are used for more complicated cases. For other cases such as Afib ablations, a special intracardiac ultrasound catheter is used to image intracardiac structures. Arrhythmias on the right side of the heart can be reached through the venous system. Arrhythmias on the left side of the heart can be reached via the femoral artery to the aorta then down through the aortic valve into the left ventricle. The second way is called trans-septal catheterization. With this technique, a needle is used to puncture the interatrial septum from the right atrium, which allows a long sheath to be passed into the left atrium.
i am scheduled for march 3rd. for an ablation in London, Ontario
Hope you are free from a fib for ever.
