The effect of atrial pacing on atrial flutter was evaluated in 36 consecutive episodes in 33 patients. Seventeen episodes occurred in a pulmonary setting, 14 of these in patients with chronic pulmonary disease. Twenty-four (67 percent) of the 36 episodes converted to sinus rhythm within one minute
A case of antepartum atrial tachyarrhythmia was detected in the 36th week of pregnancy. Cardiotocograph recordings done twice daily enabled close surveillance of the fetal condition after oxytoxin challenge testing had failed to show evidence of hypoxia. After a diagnosis of fetal cardiac arrhythmia
Experiments were conducted with 159 dogs to investigate the mechanism of persistent dysrhythmias clinically encountered after atrial-level operations. Those found after incisions to the internodal pathways (INPs) of the right atrium were analyzed using cardiac mapping in an anesthetized or
OBJECTIVE
To assess the clinical, functional state, and complications late (15-20 years) after palliative Mustard operation.
METHODS
Examination and evaluation of all patients presenting in adolescence and adult life after palliative Mustard operation for transposition of the great arteries and
METHODS
A 72-year-old man with chronic heart failure had received implantation with a pacemaker for type III sick sinus syndrome in 2002. Mixed type sleep apnea syndrome (SAS) was diagnosed in 2004, and continuous positive airway pressure (CPAP) treatment was started. However, CPAP use become
Subclinical hyperthyroidism is an increasingly recognized entity that is defined as a normal serum free thyroxine and free triiodothyronine levels with a thyroid-stimulating hormone level suppressed below the normal range and usually undetectable. It has been reported that subclinical
Patients with chronic obstructive pulmonary disease (COPD), especially during acute exacerbations of their disease, show a greater incidence of cardiac arrhythmias than healthy subjects of the same age. The type of arrhythmias found may be supraventricular (premature atrial beats, paroxysmal
OBJECTIVE
To assess the cardiac disturbances in African-American patients treated with paclitaxel.
METHODS
One-hundred-nineteen African-American patients received paclitaxel for various cancers at Howard University Hospital during the years 1993-2001. Medical records of 100 patients were available
The positive inotropic and chronotropic actions of enoximone were confirmed. At concentrations within the clinical range, enoximone prolonged the chronotropic and hypotensive action of isoproterenol in pithed rats. Very high doses of both enoximone and isoproterenol caused ventricular fibrillation
This paper reviews cardiac dysrhythmias occurring in the perioperative period. Electrocardiography was the first application of electronic monitoring to anesthesia care. The detection of dysrhythmias remains the most important use of this technology today. While the description of dysrhythmias dates
BACKGROUND
Positive pressure therapy (CPAP) in patients with cardiac arrhythmias and obstructive sleep apnea (OSAS) may have favorable effects by correcting intermittent hypoxemia and sympathetic activation.
OBJECTIVE
To assess the effect of CPAP added to pharmacological treatment in the rate
Electrocardiograms of 90 patients with arteriographically documented acute submassive or massive pulmonary embolism and no associated cardiac or pulmonary disease were studied. Patients were derived from the Urokinase-Pulmonary Embolism Trial National Cooperative Study. In massive embolism, the
Introduction: The impact of atrial arrhythmias on COVID-19-associated outcomes are unclear. We sought to identify prevalence, risk factors and outcomes associated with atrial arrhythmias among patients hospitalized with COVID-19.
