1 sty 2004 · Despite the higher age of women (n=3097, age: 73.2 years±11.3) compared to men (n=3418, age: 71.0 years±12.4, P<0.0001) at pacemaker-implantation, the overall median survival time after implantation was significantly longer: 118.0 months vs 91.7 months in men (P<0.0001).
Mobitz type II second-degree atrioventricular block (AVB) is an electrocardiographic pattern that describes what appears to be an all-or-none conduction without visible changes in the AV conduction time or PR intervals before and after a single non-conducted P wave.
12 sie 2022 · Mobitz I is a benign rhythm that generally reflects a block at the AV node and typically results in a good prognosis. On the other hand, Mobitz II reflects a block after the AV node, either at the bundle of His or one of its branches, and often results in a poorer prognosis as it has a higher risk of progressing to a 3 rd degree AV block.
6 kwi 2023 · Second-degree AV block – Intermittent atrial conduction to the ventricle, often in a regular pattern (eg, 2:1, 3:2), or higher degrees of block, which are further classified into Mobitz type I (Wenckebach) and Mobitz type II second-degree AV block.
In group 1 there were 77 patients with Mobitz type I block (mean age 69 years), in group 2, 86 patients with Mobitz type II block (mean age 74 years), and in group 3, 51 with 2:1 or 3:1 block (mean age 75 years). The five year survival was similar in all groups, being 57%, 61%, and 53% in groups 1, 2, and 3 respectively.
8 paź 2024 · Mobitz II is much more likely than Mobitz I to be associated with haemodynamic compromise, severe bradycardia and progression to 3rd degree heart block. Onset of haemodynamic instability may be sudden and unexpected, causing syncope (Stokes-Adams attacks) or sudden cardiac death.
14 sie 2023 · The prognosis for Mobitz type II varies based on the cause of the rhythm. Patients require placement of implanted pacemaker devices to avoid complications of Mobitz type II AV blocks such as decreased cardiac output, symptomatic bradycardia, and sudden cardiac arrest.
