Relationship of Fibrillatory Waves and P Waves in the Electrocardiogram

Relationship of fibrillatory waves and P waves in the electrocardiogram.

ANALYSIS of the P wave in the electro-I X cardiogram has been found to be a useful indicator of certain alterations of cardiac function. The patterns of P mitrale and P pulmonale are generally well recognized. Morris and co-workers' reported that differences in the contour of the terminal portion of the P wave in precordial lead V, separated subjects with essentially normal hemodynam-ic finding...

Effect of Cold Drinking on Electrocardiogram Waves

La localisation et le delai d'apparition de changement de l'onde (T) a la suite de l'ingestion des boissens froide laisse supposer que le refroidissement se propage par con­tiguiter et n 'intresse que les couches superficielle de l'epi­carde. Ce qui peut expliquer !'apparition de l'onde (T) faiblement negative dans les derivation D3 et avf. 

The relationship of increased left atrial volume and pressure to abnormal P waves on the electrocardiogram.

SUMMARY Left atrial volume and pressure measurements in 23 normal subjects and 117 cardiac patients were compared with several electrocardiographic criteria for left atrial disease. Both P duration in lead II and V1 terminal force (the area inscribed by the terminal portion of the P in lead VI) showed a highly significant correlation with changes in left atrial volume but related less well to i...

the relationship between learners critical thinking ability and their performance in the reading sections of the tofel and ielts test

the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...
