The initial recognition of acute myocardial infarction at the time of the emergency department (ED) visit may be difficult in the absence of typical presentations such as chest pain, diaphoresis, and radiation tenderness. Headache angina, although reported in several instances in the past with
Cardiac ischemia typically causes chest pain, variously radiating elsewhere. Convergence of cardiac nerve fibers on central pathways receiving somatic afferents from the head is likely to be responsible for the perception of cardiac ischemic pain as headache. A 47-year-old man was admitted to the
We report 2 fatal cases of angina pectoris in patients who complained primarily of headache during the ischemic attack. The first patient, who was hospitalized because of headache and chest pain, demonstrated repeated ST-segment elevation and fatal ventricular fibrillation on ambulatory ECG
BACKGROUND
Dobutamine myocardial perfusion imaging is being used increasingly for assessment of coronary artery disease. Heretofore, there have been no large series documenting its tolerance and safety. The aims of this study were to assess the tolerance, hemodynamic changes, and safety of
OBJECTIVE
This study sought to document the safety of dobutamine stress echocardiography as it has evolved at a single center and to define predictors of adverse events.
BACKGROUND
The indications and protocol for dobutamine stress testing have evolved over 5 years of clinical use, but the influence
OBJECTIVE
Aneurysmal subarachnoid haemorrhage (SAH) is a relatively common cause of out-of-hospital cardiac arrest (OHCA). Early identification of SAH-induced OHCA with the use of brain computed tomography (CT) scan obtained immediately after resuscitation may help emergency physicians make
The chemistry, pharmacology, pharmacokinetics, clinical efficacy, adverse effects, and dosage of sotalol hydrochloride are reviewed. The chemical name of sotalol hydrochloride is 4'-[1-hydroxy-2-(isopropylamino)ethyl]methanesulfonanilide monohydrochloride. Sotalol is a class III antiarrhythmic that
The use of dobutamine stress echocardiography for the evaluation of coronary artery disease is rapidly expanding. Despite its widespread use, the feasibility and safety of dobutamine stress echocardiography has not been sufficiently documented. Between November 1992 and June 1995, we performed 1000
The chemistry, pharmacology, pharmacokinetics, clinical efficacy, adverse effects, and dosage of the Class I antiarrhythmic agent moricizine hydrochloride are reviewed. Moricizine is chemically similar to the phenothiazines but does not appear to block dopaminergic receptors. Its major
The antiarrhythmic effect of encainide was evaluated in 140 patients with documented symptomatic ventricular tachycardia or ventricular fibrillation refractory to conventional agents. In 102 patients with reproducible spontaneous arrhythmia, noninvasive methods, including ambulatory monitoring and
OBJECTIVE
To assess the effectiveness, cost-effectiveness, and demand in Ontario for catheter ablation of complex arrhythmias guided by advanced nonfluoroscopy mapping systems. Particular attention was paid to ablation for atrial fibrillation (AF).
OBJECTIVE
Tachycardia Tachycardia refers to a
BACKGROUND
Stress echocardiography is an established clinical testing method and is accurate for the detection of coronary artery disease. Despite its widespread use, the safety of stress echocardiography has not been sufficiently documented in Japanese laboratories.
OBJECTIVE
The feasibility,
A 33-year-old woman complained of sudden chest pain and intense headache. She was unconscious and underwent defibrillation for ventricular fibrillation in the ambulance. In the emergency room, she was placed on an artificial respirator. Diffuse wall hypokinesis and decreased left ventricular
Levosimendan increases the sensitivity of the cardiac fibrils to calcium, favorably affects hemodynamics in patients with heart failure. It is a positive inotrope and a peripheral vasodilator. The elimination half-life of the compound is about 1 hour. The drug decreases pulmonary capillary wedge
OBJECTIVE
To investigate the effect of pseudoephedrine on heart rhythm of children with rhinitis.
METHODS
The study included 25 children diagnosed with rhinitis from March 2009 through February 2010 in the Department of Pediatrics. Holter records were obtained for 24 h before and at the fourth day
