Cholesterol and cardiac arrhythmias
Expert Review of Cardiovascular Therapy, 2010Cardiac arrhythmias are a leading cause of morbidity and mortality in the Western world. Ventricular arrhythmias are reportedly responsible for the majority of sudden cardiac deaths and atrial fibrillation is responsible for 15% of all strokes in the USA. Recent evidence suggests a role for cholesterol in the development of these arrhythmias.

Revista Española de Cardiología (English Edition), 2006
The aim of this study was to review published data on gender differences in cardiac electrophysiology and in the presentation and clinical treatment of arrhythmias. The evidence from studies published to date show that women have a higher mean resting heart rate, a longer QT interval, a shorter QRS duration, and a lower QRS voltage than men. Women have

Cardiac Arrhythmias in Children
Annual Review of Medicine, 1984Recent interest in cardiac arrhythmias in children has been stimulated by a growing awareness of primary rhythm disorders in children, by the appearance of rhythm disorders following repair of many congenital heart defects, and by recent developments in clinical electrophysiology. This chapter focuses on developmental clinical cardiac electrophysiology,

Connexins and Cardiac Arrhythmias
2006During cardiac remodeling, impulse conduction in the heart is altered by changes in excitability, electrical coupling, and tissue architecture. The impairment of normal impulse conduction is one of the factors that increases the propensity for arrhythmias. This chapter focuses on the relationship between electrical coupling between ventricular myocytes

Management of Cardiac Arrhythmias
Hospital Practice, 1985Ventricular ectopic activity that is not associated with symptoms may be an indicator of underlying coronary heart disease and should alert the physician to the need for a full evaluation of the patient's cardiovascular status and prognosis. The factors that increase the risk of sudden cardiac death are discussed, as is appropriate antiarrhythmic ...

Current Opinion in Cardiology, 1993
Cardiac arrhythmia surgery has changed dramatically in the past several years, as indicated by the articles published during the past year dealing with the surgical treatment of supraventricular and ventricular arrhythmias. With the increasing use of radiofrequnecy ablation for the treatment of arrhythmias, the Maze procedure for the cure of atrial ...

Cardiac Surgery for Arrhythmias
Journal of Cardiovascular Electrophysiology, 2004Cardiac arrhythmia surgery was initiated in 1968 with the first successful division of an accessory AV connection for the Wolff‐Parkinson‐White syndrome. Subsequent surgical procedures included the left atrial isolation procedure and right atrial isolation procedure for automatic atrial tachycardias, discrete cryosurgery of the AV node for AV nodal ...

Stroke and cardiac arrhythmias
Journal of Stroke and Cerebrovascular Diseases, 2002Stroke is frequently followed by electrocardiographic (ECG) changes. The aim of the present study was to evaluate the global incidence of these changes after ischemic or hemorrhagic strokes, but it focused on cardiac arrhythmias. In ischemic strokes, these were correlated with the side of the lesion(s).

CARDIAC ARRHYTHMIAS IN THE ELDERLY
Age and Ageing, 1982A study of 20 asymptomatic elderly people living at home or in residential care and 20 symptomatic elderly subjects (with falls, 'collapse', dizziness, 'funny turns' etc.) revealed that cardiac arrhythmias are common in both groups. Only three of the asymptomatic group and two of the symptomatic group had sinus rhythm throughout their 24-hour ...

Mechanisms of Cardiac Arrhythmias
Annual Review of Physiology, 1982The mechanisms involved in the disruption of the rate and rhythm of the heart have classically been categorized' as those due to abnormalities in impulse formation (automaticity) or those due to abnormalities in impulse conduction (59, 66). Current knowledge has expanded these concepts to include additional mechanisms of arrhythmogenesis that are just ...
