Development, Reliability, and Validity of the Medical Helping Relationship Inventory
(SAGE PUBLICATIONS, INC., 1991)
Results of five studies; which were conducted over a 4-year period, provide initial evidence that a new instrument, the Medical Helping Relationship Inventory (MHRI), can reliably and validly be used in the evaluation of ...
Results of electrophysiologic testing and long-term prognosis in patients with coronary artery disease and aborted sudden death
(Elsevier, 1991-10)
The purpose of this study was to evaluate the results of electrophysiologic testing and the long-term prognosis of 56 patients with coronary artery disease who presented with aborted sudden death unrelated to acute myocardial ...
Effects of encainide and amiodarone on the adaptation of ventricular refractoriness to an increase in rate
(Elsevier, 1990-07-15)
The ventricular effective refractory period (VERP) adapts gradually to an increase in rate, and up to several minutes may be necessary before the maximum shortening of VERP is realized when the rate increases.1,2 Quinidine ...
Management of Nonsustained Ventricular Tachycardia Guided By Electrophysiological Testing
(Blackwell Publishing Ltd, 1993-05)
Cost of catheter versus surgical ablation in the wolff-parkinson-white syndrome
(Elsevier, 1990-07-15)
In this retrospective study of 22 patients with the Wolff-Parkinson-White (WPW) syndrome, the cost of catheter ablation in 11 patients was compared with that of surgical ablation in another 11 patients. All patients in the ...
The effect of quinidine and mexiletine on the adaptation of ventricular refractoriness to an increase in rate
(Elsevier, 1991-02)
The purpose of this study was to determine the effects of quinidine and mexiletine on the adaptation of ventricular refractoriness to a change in heart rate. The ventricular effective refractory period was measured at a ...
Acute changes in pacing threshold and R- or P-wave amplitude during permanent pacemaker implantation
(Elsevier, 1990-04-15)
This study examines the changes in pacing threshold and R- or P-wave amplitude during the first 30 minutes after implantation of tined and screw-in leads. The leads examined were those of 1 manufacturer (Medtronic) and ...
Effect of rate augmentation and isoproterenol on the amplitude of atrial and ventricular electrograms
(Elsevier, 1990-07-01)
Recent studies have shown a decrease in the amplitude of intracardiac electrograms during exercise in patients with permanent pacemakers.1-3 However, the mechanism by which exercise decreases the amplitude of the intracardiac ...
Safety and Toxicity of Catheter Gene Delivery to the Pulmonary Vasculature in a Patient with Metastatic Melanoma
(Mary Ann Liebert, Inc., publishers, 1994-09-01)
Overview summary Transcatheter delivery of HLA-B7 DNA and cationic liposomes into a segment of a pulmonary artery was safely performed in 1 patient with tumor nodules in the lung. No immunologic or organ toxicities were ...
