Blood Volume Changes and Sinus Node Functionowing atrial stimulation of 85 and 145/min, whereby pulmonary arterial pressure (PAP) and systemic intraarterial pressure (SAP) were continuously recorded, cardiac output (CO) measured by thermodilution and venous blood withdrawn for radioenzymatic determination of plasma norepinephrine (PNE) and ep

Long-Term Follow-Up of Paced Patients with Sick Sinus Syndromethods 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

Termination of Pacing in Patients with Sick Sinus Syndrome and Implanted Pacemakers who Developed Ch atrial fibrillation (AF) which terminates their clinical syndrome. In these pts, termination of permanent pacing (PP) may be considered. Among a group of 100 pts with SSS, treated with implanted PMs, 27 pts (27%) developed chronic AF following implantation. Of this group, long-term PP was terminate

Electrophysiologic Effects of Reduced Oxygen Supply on the Transmembrane Potential and Membrane Curr.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

Catheter Biopsy Assessed Cardiomyopathic and Postmyocarditic Changes in Cases with Atrioventricular endomyocardial biopsy which exceeds 1300 cases has revealed that biopsy is useful in diagnosing and assessing myocardial disease. A serial biopsy study in 10 cases with acute viral myocarditis has enabled us to define the histopathological criteria of postmyocarditic change (PMC). Eighty-eight cases

Atrial Contribution in VVI Pacing2 paced patients with complete A-V block. A ratio of the number of QRS complexes preceded by P waves to the total number of QRS complexes (atrial contribution rate, ACR) was calculated. ACR was also calculated as a ratio of T-R interval to P-P interval when atrial rate was fixed. Under ventricular p

Stability of AV Conduction in Patients with Implanted Atrial Pacemakersion. 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 chamb

Atrio-Ventricular and Ventriculo-Atrial Conduction in Patients with Symptomatic Sinus Node Dysfunctiwith 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
