Occurrence Of Syncope Research Articles

Micturition syncope. Report of 24 cases.

THE occurrence of syncope associated with micturition in healthy males is an event that until recently was not widely recognized in medical circles. Before the article by Proudfit and Forteza1 there were no detailed reports in the literature. Gastaut,2 in discussing a series of 200 cases of nocturnal loss of consciousness, mentioned 40 cases of syncope occurring before, during or after micturition. Treires,3 in 1957, referred to a single case of micturition syncope. In a series of 82 cases of syncope in healthy young males, Dermksian and Lamb4 noted 4 associated with voiding. In a questionnaire, surveying 1980 United States . . .

The outlook for children with congenital aortic stenosis

A study to determine the course and prognosis of congenital aortic stenosis in children is presented. Of the seventy-three patients on whom a follow-up study was accomplished, forty-one are asymptomatic, twenty-six have symptoms, and six are dead. Five of the six patients died suddenly; and all six were under the age of 16 years. Although the occurrence of sudden death has been mentioned frequently by earlier writers, the 8.2 per cent mortality rate found in this series is higher than one is led to expect from most previous reports. For this reason, it would seem that selected cases should be considered for aortic valvulotomy. The principal indications for surgery, based upon this study, are the occurrence of syncope and easy fatigability, cardiac enlargement, and marked left heart strain.

Some Clinical Features of Complete Heart Block

A review was made of 251 cases of complete heart block. They were divided into the following groups: coronary artery disease (nonacute), 58 cases; myocardial infarction (acute), 49 cases; hypertensive heart disease, 62 cases; rheumatic heart disease, 21 cases; miscellaneous, 16 cases; "etiology undetermined," 18 cases; and digitalis intoxication, 27 cases. Among the various clinical features analyzed were the sex and age factors, the occurrence of syncope, palpitation, congestive failure, anginal pain, and the duration of life after the onset of major symptoms. Methods of treatment are discussed.

Syncope in aortic stenosis.

SYNCOPE as a manifestation of aortic stenosis was first mentioned by Cowper in 1706.1He described a patient with this disease who complained of great faintness, and now and then pain about the heart.... The occurrence of syncope in aortic stenosis was not, however, generally recognized until recently. The reports of Gallavardin,2Gravier,3Marvin and Sullivan4and Contratto and Levine5have emphasized this symptom. This report is based on a clinical analysis of 63 patients with aortic stenosis observed during a three year period at the Minneapolis Veterans Administration Hospital. A clinical diagnosis of aortic stenosis was accepted only when both an aortic systolic murmur and a thrill were present or when calcific aortic valves could be demonstrated by fluoroscopy. In 23 patients the diagnosis was proved at autopsy. ANALYSIS OF PATIENTS WITH SYNCOPE Syncope occurred in 16 of 63 patients (table 1). In 14

SYNCOPE, CONVULSIONS AND THE UNCONSCIOUS STATE

The occurrence of syncope and convulsions due to a hyperactive carotid sinus reflex has been receiving deserved emphasis lately. 1 The carotid sinus is the bulbous dilatation at the bifurcation of the common carotid artery. Normally an increase in intrasinal pressure reflexly produces a moderate decrease in arterial tension, cardiac rate and output of epinephrine, while respiration and peristalsis are increased. In a patient with a hypersensitive carotid sinus, stimulation of the sinus by pressure will often induce syncope or convulsions as well as other manifestations. The three dominant sinal responses are: (1) the vagal type, with the efferent impulse traveling over the vagus nerve to produce sinoauricular or auriculoventricular block, with resultant asystole and syncope; (2) the depressor type, the efferent arc of which over the aortic depressor nerves accounts for vasodilatation and hypotension unassociated with bradycardia, and (3) the cerebral type, in which syncope occurs without cardiovascular changes.
