atrioventricular block/headache

Influenza virus causes annual epidemics of respiratory illness characterized by sudden onset of fever, malaise, myalgias, headache, cough, and other respiratory complains. Each year in the United States, it is estimated that this debilitating respiratory illness accounts for 294,000 excess

Background: The biological behaviour and clinical significance of mercury toxicity vary according to its chemical structure. Mercury differs in its degree of toxicity and in its effects on the nervous, digestive and immune systems as well as on organs such as the lungs, kidneys, skin, eyes and

A 35-year-old man was hospitalized after a sudden onset of transient syncopal attack without accompanying complaints of headache or nausea. He was slightly disorientated but neurologically normal. He had a blood pressure of 150/90mmHg and a pulse rate of 40/min. An ECG showed marked sinus

BACKGROUND Paroxysmal atrioventricular (AV) block is an ill-defined entity, previously described in sporadic cases in association with vasovagal reaction, coronary angiography and distal conduction disease. METHODS We describe 20 patients (10 women) aged 26 to 80 years with symptomatic paroxysmal AV

BACKGROUND High dose verapamil is an increasingly common preventive treatment in cluster headache (CH). Side effects include atrioventricular block and bradycardia, although their incidence in this population is not clear. METHODS This audit study assessed the incidence of arrhythmias on high dose

ACT-280778 is an oral, non-dihydropyridine, dual L-/T-type calcium channel blocker. This phase 2a, double-blind, randomized, placebo- and active-controlled study investigated the efficacy and safety of 10 mg ACT-280778. Patients with mild-to-moderate essential hypertension received once-daily

Cerebral hyperperfusion syndrome is a rare but well-described complication following carotid endarterectomy or stenting. Clinical signs are ipsilateral, throbbing, unilateral headache with nausea or vomiting, seizures, and neurological deficits, with or without intracerebral abnormalities on CT

A 34-year-old man with AIDS was admitted to the hospital with a one-week history of cough, chest pain, and fever. Radiography revealed a cavitating left upper lobe lesion. Two weeks later he developed a headache associated with a contrast enhancing lesion in the right parietal lobe. The patient had

BACKGROUND Lacosamide is an antiepileptic drug whose exact mechanism of action remains unknown. It acts by increasing the slow inactivation of the voltage-dependent sodium channels of the cell membranes. It is indicated in the treatment of focal seizures with or without secondary generalisation and

Borrelia burgdorferi (B. burgdorferi) is a spirochete bacterium that is transmitted via the Ixodes tick. Infection results in Lyme disease with possible cardiac manifestations, which is also known as Lyme carditis. Patients can present with bradycardia due to rapidly fluctuating

A 23-year-old black female was referred to the University Hospital of Oklahoma because of "sleep trouble." She complained of falling asleep easily during the daytime. A sleep study was performed which showed prolonged apnea, up to 35 seconds, and prolonged asystole, up to seven seconds, with

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

Diprafenone is a new antiarrhythmic drug with a dominant local anaesthetic action and an additional beta-sympathicolytic activity. In this study, the results of long-term treatment (8 months on average) obtained from 27 patients with chronic ventricular arrhythmias are reported. Before diprafenone,

The goals of stable angina pectoris treatment are: (i) symptom relief and increase in angina-free walking time; and (ii) reduction of mortality and adverse outcome. Strategies used for plaque stabilisation resulting in a reduction in cardiovascular mortality and morbidity are: smoking cessation;
