Such pauses, if prolonged, leads to a danger of the heart not starting again, and hence he need for a pacemaker ( and monitoring to see if this is happening). Sometimes going in and out of abnormal rhythms the heart does not like the change and may decide to give up and stop ( asystole). I hope this answers your question to why a pacemaker cannot help in atrial flutter. The circular current causes the atria to 'flutter' ( beat very fast), this current is in turn transmitted, to the maximum possible by the conducting system of the heart, to the lower chambers, and hence the 150 beats per minute. No pacemaker will stop this circular current as the pacemaker wires are connected to usually both the upper and lower chambers of the heart ( the atrium and ventricle) and the pacemaker delivers a little electrical shock to those chambers for stimulating the heart muscle. If the scar is too small some healing may occur and you may not get success in the long run. All the ablation catheter does is to produce a small burn/scar and this cannot conduct the impulse. The flutter ablation cuts the circular conduction resonsible for the atrial flutter, above the tricuspid valve ( the left side of the heart between the atrium and the ventricle). The flutter ablation is much more simple than the fibrillation ablation. The ablation operation involves an electrical burn. This editorial refers to ‘Anatomical variations of the right coronary artery may be a source of difficult block and conduction recurrence in catheter ablation of common-type atrial flutter’ by H.U. Been there, and had an electrical cardioversion ( some people can have a chemical cardioversioin) and a cardiac catheter flutter ablation.Īblations may be for atrial flutter, fibrillations, or sino-atrial junction. Only you can make the decisions but you need information.Ītrial flutter can be very uncomfortable with your heart thumping away at 150 beats per minute. There are lots of options, none without potential problems. Flutter is a major PITA, I know, but you really need to be involved in your treatment. They have an obligation to educate you on your condition, treatments, and treatment alternatives. The "only has 15 minutes" thing isn't a valid excuse. In any case, you really need to buttonhole your EP and have him explain exactly what they're doing to you. Perhaps they've given you antiarrhythmic drugs (ameoderone, sotalol, or a number of others) that tend to surpress the heart rate and are using the pacemaker to boost it back to a reasonable rate? There has to be another reason for the pacemaker. A pacemaker can only make the heart go faster, which certainly isn't what's needed when you're in flutter. Flutter, alone, isn't a reason to get a pacemaker (alone).
