Cardiac arrhythmias during exercise in severe chronic obstructive pulmonary disease.
We studied the effect of maximal exercise on the prevalence of arrhythmias in 122 subjects with severe COPD. At rest, ten subjects had supraventricular arrhythmias while 13 had unifocal VPB greater than or equal to 6/min or ventricular bigeminy. At peak exercise, six subjects had supraventricular arrhythmias while 24 had VAs. Univariate and multivariate analysis with logistic regression did not...
متن کاملThe International Sepsis Forum's frontiers in sepsis: high cardiac output should be maintained in severe sepsis
Despite a usually normal or high cardiac output, severe sepsis is associated with inadequate tissue oxygenation, leading to organ failure and death. Some authors have suggested that raising cardiac output and oxygen delivery to predetermined supranormal values may be associated with improved survival. While this may be of benefit in certain patients, bringing all patients to similar, supranorma...

node as the region responsible for activation of the heart.1 Laslett first suggested sinus node dysfunction as a cause of bradycardia in 1909, and during the 1950s and 1960s Short, Ferrer, Lown, and others described the clinical spectrum of sinus node dysfunction that is commonly called the “sick sinus syndrome resting sinus bradycardia.”2-5 Sinus node dysfunction can have multiple electrocardi...
متن کاملStress and Cardiac Arrhythmias
Stress can exert adverse effect on cardiovascular health. Psychosocial stress adversely affects the autonomic homeostasis. This in turn can result in metabolic abnormalities, inflammation and dysfunction of endothelium [1]. Changes in the autonomic homeostasis can be a major trigger for ventricular tachyarrhythmias [2]. Increased sympathetic nervous activity can cause increased proarrhythmic re...
متن کاملCardiac arrhythmias and pacing.
Clinical trials. In the last two years, a number of landmark clinical trials have been published which further our understanding and clinical management of patients with atrial fibrillation (AF). Two of the major goals in the treatment of this condition include reducing progression or recurrence of the arrhythmia and decreasing the risk of cardiovascular events, thereby improving quality of lif...
