The aim of the study was to evaluate the prevalence of electrocardiography (ECG) abnormalities in subjects with spontaneous pneumothorax. Forty consecutive patients (mean age 43.7 +/-19.1 years) with spontaneous pneumothorax participated in the study. There were 22 cases of left-sided and 18 cases of right-sided pneumothorax. The mean relative volume of pneumothorax was 51.4 +/-24.7% according ...

The early pathological accounts of poliomyelitis were limited to descriptions of the changes in the neuraxis. Wickman (1907) in his classical monograph on the disease alluded to the common occurrence of lymphoid hyperplasia, as did Harbitz and Scheel (1907), and Peabody et al. (1912), but none of these writers mentioned myocardial lesions. Robertson and Chesley (1910) observed swelling of myoca...

One of us (Rogen, 1957) has reported a patient in whom extensive cardiographic abnormalities were associated with massive urticaria, the abnormalities being of short duration and clearing with rapid recovery from the urticaria. Her condition is summarized shortly as Case 2. The first patient reported here as Case 1 had associated mild urticaria only, but the electrocardiogram showed features si...

Fabry disease is an X-chromosome-linked lysosomal storage disease characterized by a deficient activity or, in most males, absence of the enzyme α-galactosidase A (a-Gal A) leading to systemic, primary lysosomal accumulation of globotriaosylceramide (Gb3) (1). Recent literature refers to an overall birth prevalence of 1:40,000-170,000; however, such data do not allow an estimation on an actual ...

An electrocardiographic study of 110 patients with old myocardial infaretion was made. Chan.Ige of posture, by causing rotation of the heart on its axes, frequently altered the evidence of infarction. These changes were most evident in posterior infarction. The "labele(l" area (lid the following with respect to the exploring electrode: (1) disappeared, (2) if absent in the supine posture, the e...

The electrocardiograms were compared in two groups of schizophrenic patients (Experimental group N=43, Control group N=60). The selected cases were given 4 mg of Trifluoperazine daily by IM route for five days. A 12 lead ECG was taken thrice in each case. A statistical analysis of the data showed definite changes in many of the ECG variables. Comparatively more changes were noticed in the exper...

the results obtained in the present investigations point to a definite correlation between the onset of myocardial injury, electrocardiographic changes and biochemical changes. changes in the electrocardiogram and elevated serum levels were paralleled by an increased excretion of magnesium in urine as early as one hour. serum calcium and serum potassium levels did not show any significant resul...

Y THE TIME the patient with acute myocardial infarction is first examined, his electrocardiogram may already show changes in the RS-T segment alone, in the T wave alone, in the QRS complex alone, or in any combination of the three. Changes in any of these portions of the ventricular complex and particularly in the QRS may not appear for hours or days. Some never show distinctive electrocardiogr...
