We examined the effect of chronically administered digoxin on atrioventricular (A-V) conduction in nine cardiac transplant recipients. We assessed A-V conduction by measuring the duration from the pacing stimulus to the onset of the QRS complex (S'R interval) and by determining the occurrence of Wenckebach periodicity during rapid atrial pacing. We made measurements during a control period and ...

This research is useful to improve the learning outcomes of students in class IVB ipas through puzzle media at SDN Peterongan. The used a Classroom Action Research (PTK) design and was conducted over two cycles. assessment shows that there an increase each cycle. In pre-cycle, who were complete 8 or percentage 33% while those not 16 incomplete 67%. cycle I, 67% incomplete. II, 20 83% 4 17% It c...

rates ranged between I58 and I94 a minute. This phnomenon (also observed by Lewis, Feil, and Stroud, I918-I920) was manifested by a gradual prolongation of the stimulus-to-atrial electrogram intervals until one stimulus failed to reach the recording electrodes. The localization of the site ofdelay and block could be made exclusivelyfrom the intracardiac recordings, since the surface leads showe...

The present case demonstrated a rare situation alternating between a repetitive atrial tachycardia (AT) and ventricular tachycardia (VT). A unique induction mechanism was noted in which the VT was induced after Wenckebach AV node conduction block following the repetitive rapid AT.

OBJECTIVE To describe the outcomes for patients treated at a single institution, who sustained incomplete bisphosphonate-induced femoral fractures. DESIGN Retrospective review. SETTING University-based academic medical center. PATIENTS Thirty-one patients with 43 incomplete fractures met the inclusion criteria. INTERVENTION Nonoperative management or surgical intervention for fractures ...

This article presents results from a small, introductory clinical study offering a simplified regimen medical abortion to women in Turkey. A total of 208 women from five sites were recruited from July 2000 through March 2001. All eligible consenting women were given 200 mg oral mifepristone at the clinic followed by 400 microg oral misoprostol 2 days later either at home or at the clinic. The o...

In addition to the familiar basic framework of the Categories, the current standards EN ISO 13849 Parts 1 and 2 (Safety of machinery – Safety-related parts of control systems – Part 1: General design principles [1], Part 2: Validation [2]) also describe a probabilistic assessment of the functional safety achieved. Whereby there have been misinterpretations during the application of the standard...

PURPOSE To analyze the effectiveness and occurrence of complications, in addition to hospitalization time and blood losses. METHODS Thirty patients were assigned alternatively and consecutively to one of two groups (15 to the Curettage Group and 15 to the Manual Vacuum Aspiration Group). The following variables were analyzed: effectiveness of the method, occurrence of complications, time befo...
