The most widely available medical management option in the stable patient is procainamide. The result is an increase in ventricular rate and possible degeneration into VT or VF. This procedure involves the use of energy, either through heat or freezing, to eliminate (ablate) the areas of heart muscle that are causing the heart to beat irregularly. Catheter ablation is an emerging technique that is used to treat atrial fibrillation and atrial flutter. Conduction through the AV node is actually a brake on AP conduction, ceasing its propagation path in the ventricleĪV nodal blockade can thus be catastrophic, preferencing conduction via the AP and leading to uninhibited propagation through the ventricles. (AFib)/A-Flutter INITIAL Status the treating cardiologist describing all items on the AFib/A-Flutter Status Report sheet. Catheter Ablation for Atrial Fibrillation & Atrial Flutter. Normally, anterograde conduction occurs via both the AP and AV node, and these wavefronts fuse in the ventricles.Most APs have a shorter refractory period than the AV node, hence the ventricular rate can be more rapid if AV conduction occurs preferentially via the AP. ![]() During A-fib, the atria quiver or fibrillate instead of contracting or squeezing in a normal organized fashion. WHAT IS ATRIAL FIBRILLATION In atrial fibrillation (A-fib), the upper chambers of the heart (the atria) do not work correctly because of abnormal electrical activity. adenosine, calcium channel blockers, beta blockers) should be avoided for two reasons: Some people have A-fib or atrial flutter, and some have both. Treatment with AV nodal blocking drugs (e.g. Just as in atrial fibrillation, not all of the P waves are able to conduct through the atrioventricular node, and thus the ventricular rate will not be as fast. However, it is in the more stable patient that we must be cautioned with the presence of an AP. In patients that are unstable due to AF, urgent synchronised DC cardioversion is required. In certain patients, the occurrence of transient, simultaneous atrial fibrillation and flutter is possible.
