TL;DR: Although serial plots of heart rate and MET costs were similar to those previously reported for different population samples, the present data further refined these values.

TL;DR: In four patients with Prinzmetal's variant form of angina, the attack was induced by the combined administration of epinephrine and propranolol and severe spasm of a large coronary artery mediated by alpha-adrenergic receptors is responsible for the attack.

TL;DR: The utility of the QT interval as an indicator of cardiac states vulnerable to arrhythmias should be further investigated and mechanisms operating in the reflection of ventricular recovery by theQT interval are elucidated.

TL;DR: Total anomalous pulmonary venous connection (TAPVC) is failure of development of the common pulmonary vein, with consequent ersistence and enlargement of embryonic collaterals between the lungs and the systemic veins.

TL;DR: The goal should be the surgical correction of truncus during the first and second months of life, in view of the difficulties associated with pulmonary artery banding.

TL;DR: The ST segment in a single right-sided chest lead, CR4R, has been studied in 92 consecutive patients with acute inferior transmural left ventricular myocardial infarction, and strongly indicated a significant extension of the infarctions to the posterior free right ventricular wall according to autopsy findings.

TL;DR: The view that protection against VF during coronary artery occlusion and release may require different antiarrhythmic measures is supported, whereas the changes in VF threshold following reperfusion may be due to washout products of cellular ischemia.

TL;DR: The right and left cardiac sympathetic nerves have a different influence upon cardiac excitability, and blockade of the right stellate ganglion reduced or abolished occlusion-induced arrhythmias.

TL;DR: Sixty-five cases of nonbacterial thrombotic endocarditis (NBTE) were discovered at autopsy during a 10 year period-an incidence of 1.6 per cent in the adult autopsy population; adenocarcinoma represented the most frequent histologic type of related neoplasm.

TL;DR: Breeding experiments confirm that discrete subaortic stenosis in Newfoundland dogs is a specific inherited trait and indicate that SAS is inherited as a polygenic trait or as an autosomal dominant trait with modifiers.

TL;DR: It is suggested that suppression of plasma FFA with GIK infusion may be associated with a significant reduction in the hospital mortality rate of acute myocardial infarction.

TL;DR: There is, therefore, no physiologic basis for advising cardiac patients to utilize the MOB position during sexual intercourse, and the differences in mean HR, BP, and pressure rate product (PRP) were not statistically significant with regard to position at rest intromission, orgasm, or during the recovery period.

TL;DR: Cessation of anticoagulation for 3 to 5 days appears safe in patients with aortic prostheses who require subsequent noncardiac operations, and the incidence of thromboembolism in patients after mitral or combined valve replacement is high.

TL;DR: It is concluded that lupus cardiomyopathy associated with an impairment of left ventricular function may be apparent in young women with SLE who have no clinical signs of cardiac dysfunction.

TL;DR: The evidence presented suggests a causal relationship between administration of dextroamphetamine and the cardiomyopathy, and the similarities to the myocarditis associated with pheochromocytoma are discussed.

TL;DR: Significant clinical predictors of fatal outcome included pulmonary vascular congestion, "northwest" axis deviation, and a cardiac index less than three L./min./M.2.

TL;DR: This sequence fills the gap as an intermediate phase between the normal and the two individuals described here who developed pain after anaphylactic shock, then proceeded, perhaps through this phase, to develop transmural infarction.

TL;DR: Data demonstrate that, in addition to the lack of specificity of the lung perfusion scan for the diagnosis of pulmonary thromboemboli, there is a considerable problem of interpretation in this patient population.

TL;DR: It is concluded that disopyramide is effective and safe with serum levels ranging from 2.39 to about 3.60 mug per milliliter, and this can be maintained with 100 mg.

TL;DR: Oral mexiletine was well tolerated in most patients and regular hematological and biochemical screening revealed no problems of toxicity.

TL;DR: Patients with serious underlying disease or with diminished hepatic clearance of lidocaine appear to be predisposed to adverse effects from this drug, which is more common in elderly individuals, in those who died, and in those with long hospitalizations.

TL;DR: Alcoholic subjects differ in the incidence of cardiomyopathy, and abnormal myocardial function was evident in males but not in females, suggesting that sex is a determinant of the toxic effects of ethanol on myocardium.

TL;DR: This article summarizes and classifies 15 different types of artifacts observed from dynamic electrocardiography which appear partly as pseudo-arrhythmias mimicking supraventricular, ventricular, junctional, and dissociative rhythms and can be misleading in the interpretation of Q-waves, S-T-segments, and T-waves.

TL;DR: Extended ethanol intake in the absence of evident malnutrition resulted in demonstrable intraventricular conduction abnormalities and morphologic alterations which were related to duration of ingestion, consistent with a cumulative toxic effect of ethanol.

TL;DR: Unstable angina is a syndrome which comprises a spectrum of symptomatic manifestations of coronary artery disease which lies between stable angina pectoris and acute myocardial infarction and the drug has effectively controlled pain in several studies and is now widely used to manage unstable angina.
