WebTypes of atrioventricular nodal reentry tachycardia (AVNRT). Atypical AVNRT (fast-slow): 10% of all cases of AVNRT In atypical AVNRT the fast pathway conducts the impulse in antegrade direction while the slow pathway conducts it in the retrograde direction. The P-wave will be visible before the QRS complex. WebDuring the follow-up period of 17 ± 8 months, 2 patients had recurrence of clockwise atrial flutter, I patient had new onset of atypical atrial flutter, and 2 patients had new onset of atrial fibrillation. Conclusions: Counterclockwise and clockwise atrial flutters may have overlapping slow conduction areas with different exit sites. china shenhua energy annual reportWeb29 apr. 2024 · 1 INTRODUCTION. Catheter ablation (CA) of atrial fibrillation (AF) is a well-established procedure for the treatment of drug-refractory AF.

WebAtrial flutter is a type of supraventricular arrhythmia. This means it’s an abnormal heart rhythm that starts in the upper chambers of your heart. With atrial flutter, your heart beats in a fast but consistent pattern. A normal heart rate is 60 to 100 beats a minute when you’re at rest. Atrial flutter can make your heart’s upper chambers ... Web1 okt. 2024 · Flecainide slows down atrial conduction, reducing the flutter rate by ∼1/3. 9 That, together with its infrequent capability of ‘organizing’ AF into AFL can give rise in AFL with 1:1 conduction, resulting in very high ventricular rates, which can potentially degenerate into life-threatening arrhythmias and cause death. 1, 3 Thus, 1:1 AFL is a very serious …
