Malin Nordström,Karin Axelsson,Ulf Melinitude of the atrial potential in patients with Sick Sinus Syndrome (SSS) was significantly lower than in those with Atrio-Ventricular Block (AVB) (by PSA, 2.2 ± 1.3 mV vs. 3.9 ± 1.1 mV, p < 0.001; by endocardial electrogram, 2.7 ± 1.5 mV vs. 4.6 ± 1.7 mV, p < 0.001). The slew rate was slightly, butIndecisive 发表于 2025-3-27 03:57:39

Peter M. Bednar,Christine Welchthods employed were atrial pacing (AP) in 36 (including 2 cases of sequential atrioventricular pacing) and ventricular pacing (VP) in 42 patients. The study was made to compare AP with VP with respect to cardiac output, symptoms and incidence of thromboembolism, and to evaluate the long-term results无意 发表于 2025-3-27 17:01:24

Jonna Kangas,Anna-Leena Lastikka.5 mllmin. Within 10 minutes, all the hearts showed a 2 º AV block, with significant prolongation of intraatrial (16%), intra-A V nodal (223%) and His-Purkinje (23%) conduction times before the 2 º A V block developed. Effects of hypoxia were studied in 7 spontaneously beating small (0.2 x 0.2 x 0.1认为 发表于 2025-3-27 23:36:20

Bodil Formark,Heta Mulari,Myry Voipioion. Despite the accepted observation that many patients with sinus node dysfunction also have atrioventricular conduction disease, data does not exist on the development of atrioventricular block in those patients with permanent single chamber atrial pacing. Of 70 patients who received single chambPRO 发表于 2025-3-28 11:49:40
Aino Tormulainen,Heta Mulari,Myry Voipiowith symptomatic sinus node dysfunction (SND) electro physiological studies were performed before pacemaker implantation. Patients were divided into two groups: Group I pts (18) with intact antegrade A V conduction (A VNW ≥ l30/min); Group II pts (8) with impaired antegrade AV conduction (AVNW < 130
