Abstract

Prehospital treatment of new-onset supraventricular arrhythmias can be attempted by physician-staffed mobile intensive care units to decrease the hospitalization rate and expense. Identification of patients suitable for at-home pharmacological treatment may help in the triage of patients with new-onset atrial fibrillation (AF). In the present investigation, the value of several clinical variables to predict the success of pharmacological at-home cardioversion was tested. A total of 924 patients with new onset (less than 24 h) AF, rescued by the Florence Mobile Coronary Care Unit (MCCU), were included in the study. By univariate analysis, female sex, palpitations as symptoms leading to MCCU call and a short delay between symptom onset and MCCU intervention were associated with a favourable outcome of treatment, whilst dyspnoea as the main complaint requiring MCCU intervention and the association of AF with an acute cardiovascular event (angina, acute myocardial infarction or pulmonary oedema) were negatively associated with the success rate of treatment. The cardioversion rate was not significantly different in patients with underlying heart disease or in patients with lone atrial fibrillation. By multivariate analysis, only sex...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
