Thirty-five consecutive patients with unilateral posterior dislocation of the hip were studied for complications at an average follow-up of 4.6 years (range 2–10 years). Thompson–Epstein type IV dislocation was most frequent (10/35), reflecting an increase in high-speed motor vehicles in the developing countries. It is also a severe injury that leads to a… (More)
OBJECTIVES The purpose of this study was to determine whether patients with paroxysmal "lone" atrial fibrillation (AF) have an abnormal atrial substrate. BACKGROUND While "AF begets AF," prompt termination to prevent electrical remodeling does not prevent disease progression. METHODS Twenty-five patients with paroxysmal lone AF, without arrhythmia in… (More)
INTRODUCTION Sites of complex fractionated atrial electrograms (CFAEs) and highest dominant frequency (DF) have been proposed as critical regions maintaining atrial fibrillation (AF). This study aimed to determine the minimum electrogram recording duration that accurately characterizes CFAE or DF sites for ablation without unduly lengthening the procedure.… (More)
The number of patients with implantable cardioverter-defibrillator (ICD) is rapidly increasing due to their expanding indications. Amongst the various types of electromagnetic interferences, little is reported about the effects of radiotherapy. We report a case of electrical reset of a single chamber ICD by scattered irradiation from radiotherapy.
BACKGROUND This study was undertaken to determine the prevalence of coronary artery disease in patients with rheumatic heart disease undergoing valve surgery. METHODS AND RESULTS Consecutive patients with rheumatic heart disease (n=376) who were above the age of 40 years, and scheduled for valve surgery underwent diagnostic coronary angiogram to delineate… (More)
AIMS To characterize the atrial remodelling in mitral stenosis (MS). METHODS AND RESULTS Twenty-four patients with severe MS undergoing commissurotomy and 24 controls were studied. Electrophysiological evaluation was performed in 12 patients in each group by positioning multi-electrode catheters in both atria to determine the following: effective… (More)
Atrial fibrillation (AF) is the most common sustained arrhythmia to occur in humans. Several predisposing substrates such as increasing age, heart failure, hypertension and valvular heart disease have been identified. The use of illicit drugs as the substrate for AF is not frequently recognized.
PURPOSE To compare the efficacy of sublingual piroxicam 40 mg with intramuscular diclofenac 75 mg in treatment of acute renal colic. The secondary objective was to look for factors that can affect the severity of the pain and pain relief in acute renal colic. MATERIALS AND METHODS One hundred patients with acute renal colic were randomized into two… (More)
Evidence from noninvasive studies suggests magnesium has a differential effect on atrioventricular nodal (AVN) pathways. To further explore the electrophysiologic effects of intravenous magnesium sulfate (MgSO(4)) on supraventricular tachycardia, with particular reference to AVN conduction pathways, we studied 23 patients with supraventricular tachycardia… (More)
OBJECTIVES The aim of this report was to study the effect of chronic stretch reversal on the electrophysiological characteristics of the atria in humans. BACKGROUND Atrial stretch is an important determinant for atrial fibrillation. Whether relief of stretch reverses the substrate predisposed to atrial fibrillation is unknown. METHODS Twenty-one… (More)
