Left ventricular dysfunction due to atrial fibrillation in patients initially believed to have idiopathic dilated cardiomyopathy.
TL;DR: In some patients initially considered to have idiopathic dilated cardiomyopathy, AF with rapid ventricular response may be the primary cause rather than the consequence of severe LV dysfunction, and LV dysfunction may be completely reversible with ventricular rate control.

Disturbances of rate, rhythm and conduction in acute myocardial infarction: A prospective study of 100 consecutive unselected patients with the aid of electrocardiographic monitoring
TL;DR: It seems that: it is most likely to occur on the first day and is often preceded by ventricular ectopic beats or ventricular tachycardia, and it is estimated that at least 25 per cent of patients with this arrhythmia could be resuscitated.
Journal ArticleDOI
Acute phase of myocardial infarction.
TL;DR: Early initiation of intensive care not only prevents deaths from ventricular fibrillation but also diminishes the incidence of shock and pump failure by preventing or immediately correcting dysrhythmias and limiting the size of the myocardial infarct.
Journal ArticleDOI
Myocardial Infarction and Atrial Arrhythmias
TL;DR: By combination of a knowledge of the anatomy and pathology of the human coronary arteries with the observation of atrial arrhythmias during acute myocardial infarction, an accurate diagnosis of the point of coronary occlusion can often be made.

Operant conditioning of heart rate in patients with premature ventricular contractions.
Theodore Weiss,Bernard T. Engel +1 more
TL;DR: In this article, the operator conditioning of heart rate (HR) was carried out in 8 patients with premature ventricular contractions (PVCs) and all of the patients showed some degree of HR control.

Differentiation of acute coronary insufficiency with myocardial infarction from coronary occlusion
TL;DR: This work has shown that in sudden death due to disease of the coronary arteries an acute occlusion frequently is not found, and that the two types of infarction differ sharply in their pathogenesis and in the pathologic changes they present.
Journal ArticleDOI
Cardiocirculatory Performance in Atrial Flutter
TL;DR: Data obtained in 12 patients with atrial flutter indicate that this arrhythmia was associated with a low cardiac output in those subjects with intrinsic heart disease and, in general, when failure existed, the type of pulmonary hypertension noted in subjects with flutter, differed from those in sinus rhythm.

Neosynephrine in treatment of paroxysmal supraventricular tachycardia.
TL;DR: These studies suggest that intravenous injection of Neosynephrine, or some other rapid-acting vasopressor substance, will prove to be the treatment of choice in selected cases of paroxysmal supraventricular tachycardia.
