Increasing maternal mortality and incidence of arrhythmias in pregnancy have been noted over the past 2 decades in the United States. Pregnancy is associated with a greater risk of arrhythmias, and patients with a history of arrhythmias are at significant risk of arrhythmia recurrence during pregnancy.

A historical overview is given on the techniques to record the electrical activity of the heart, some anatomical aspects relevant for the understanding of arrhythmias, general mechanisms of arrhythmias, mechanisms of some specific arrhythmias and nonpharmacological forms of therapy.

Progress in Pediatric Cardiology, 2000
A spectrum of distinctive clinical presentations and electrocardiographic patterns have been recognized in neonates with ventricular arrhythmias. These may range from an incidental finding on a routine physical to cardiovascular collapse due to ventricular fibrillation.

The Indian Journal of Pediatrics, 2006
Neonatal arrhythmias are not uncommon; however, they rarely cause hemodynamic compromise. This paper aims to study the etiology, spectrum and outcome of neonates with arrhythmias who presented to a pediatric department.All neonates, either inborn or brought to the pediatric emergency with rhythm disorders, between August 1999 to August 2002, were ...

Cardiac Electrophysiology Review, 2003
Cardiac arrhythmias are difficult to define epidemiologically. It therefore follows that data available on their actual incidence and prevalence is limited. Although many of the available studies can be criticised due to methodological flaws, overall there do appear to be some differences in the incidence and prevalence of arrhythmias in different ...

The prevalence of arrhythmias in pregnant women are rising, particularly among women with a history of structural heart disease or prior arrhythmia. The physiological changes of pregnancy increase the risk of both benign and pathologic arrhythmias, with atrial fibrillation representing the most common pathologic arrhythmia.

The presence of arrhythmias in athletes is not infrequent. Bradyarrhythmias are more frequent in sportsmen than in the general population. This fact is often due to a 'relative vagal hypertony', owing to a training effect. Tachyarrhythmias are also present in sportsmen in almost the same percentage as in sedentary people.

Journal of Cardiovascular Pharmacology, 1991
In view of the broad spectrum of arrhythmias and their considerable spontaneous variability, there is a need for a classification of arrhythmias as a basis for scientific and clinical decision making. From the clinical point of view, a classification should consider (a) hemodynamic consequences, (b) prognostic significance of arrhythmias, and (c ...

Athletes and Arrhythmias. Athletes are thought the healthiest segment of the population. Yet, there is a general appearance that athletes are more prone to sudden cardiac death and arrhythmias than nonathletes. Bradycardias in athletes are nearly universal, but advanced heart block is usually pathologic.

Cardiologia (Rome, Italy), 1995
In this study, we assessed one particular aspect of the arrhythmogenic phenomena that occur during reperfusion secondary to thrombolysis, that is the therein involved metabolic mechanisms. The employed experimental model (isolated Langendorff-perfused rat heart) allowed us to distinguish which factor involved during ischemia, low coronary flow or low ...
