Excerpt The association of paroxysmal ventricular tachycardia with acute left ventricular failure and pulmonary edema in an individual with no demonstrable organic heart disease is a rarity. Such e...

We reviewed electrocardiograms of 23 patients with intermittent left bundle-branch block. A characteristic electrocardiographic pattern consisting of right and mid-precordial deep symmetrical T-wave inversions was detected during normal conduction in 19 of the 23. Of the seven patients who had cardiac catheterization, only two had findings suggestive or organic heart disease and only one had significant obstructive coronary disease. Thus we conclude that patients with intermittent left bundle-branch block frequently have T-wave inversions in right and mid-precordial leads during normal conduction that do not necessarily reflect coronary disease. These T-wave changes are similar to those after termination of chronic right ventricular pacing (left bundle-branch pattern), suggesting that both patterns of abnormal ventricular activation can produce abnormal repolarization when activation returns to normal.

Excerpt Although atrial fibrillation is generally associated with organic heart disease, it can also occur without any evidence of structural or functional alterations in the heart (1). It then can...

Excerpt Paroxysmal ventricular tachycardia is most often associated with organic heart disease and in this setting is of ominous prognostic import (1-3). Less commonly, this arrhythmia occurs in yo...

Excerpt Because of the recent interest in the syndrome of the short P-R interval associated with a prolonged QRS complex, without organic heart disease (Wolff-Parkinson-White syndrome), as evinced ...

Excerpt Until a few years ago inversion of the T-waves in Lead I or II of the electrocardiogram was considered evidence of organic heart disease. Recently, however, certain exceptions to this gener...

Excerpt Paroxysmal supraventricular tachycardia is a common functional heart disorder of all ages but particularly of young adults without organic heart disease. Relatively few attacks are seen by ...

Excerpt The purpose of the present communication is to present seven cases of organic heart disease in which there is isolated involvement of the pulmonary artery or valve, and to indicate the impo...

Excerpt The onset of auricular fibrillation is generally considered an unfavorable event in the course of organic heart disease. The reports in the literature indicate that the average duration of ...

Excerpt That anemia can be the primary cause of organic heart disease is doubtful; it can, however, give rise to quite abnormal subjective and clinical signs. For such disturbances to arise it is n...

Excerpt The mechanism of heart failure is still the subject of investigation. In recent years, however, observations have been made which lead to a clearer understanding of its pathological physiol...

Excerpt The importance of determining the functional capacity of the myocardium in organic heart disease has engaged the attention of cardiologists for many years; but in 1922, Brittingham and Whit...

Excerpt That paroxysmal ventricular tachycardia may occur in the absence of underlying organic heart disease has been established by numerous individual case reports1-14and studies of large groups ...

Excerpt Paroxysmal ventricular tachycardia in a patient without demonstrable organic heart disease is comparatively rare. Armbrust and Levine1in a review of 107 cases reported no organic heart dise...

Excerpt An evaluation of the ability of the patient with organic heart disease to withstand operation is a matter of great importance and also of great difficulty. In 1930, Butler, Feeney and Levin...

The amplitude of the fibrillatory waves and the magnitude of the P terminal force in lead V1of the electrocardiogram were examined in 30 patients without evident organic heart disease who ...
