Premature Ventricular Depolarization
ثبت نشده
چکیده
ADIFFERENCE has been observed in certain instances between the onset of QRS in intracavitary and surface limb leads. Simultaneous tracings demonstrate that when premature ventricular depolarization exists the early rapid growth in magnitude of potential recorded by intracavitary leads may be nearly or totally inapparent in surface leads. Following premature depolarization changes occur in intracavitary and surface leads that shed light on the electrical basis for surface electrocardiographic inscription of " fusion beats," initial and terminal QRS abnormalities, and secondary ST-T wave changes.

ABSTRACT: Mitral Valve Prolapse (WVP) in one of the commonest cardiac abnormalities. Echocardiography has generally been accepted as the diagnostic modality of choice, To assess the characteristic symptoms signs and electrocardiographic abnormalities of MVP results of prospective 500 age and sex matched healthy subjects without echocardiographic MVP (control subjects). The diagnostic criteria...

متن کاملRelationship of ventricular excitability characteristics to ventricular arrhythmias in dogs.
The relationship of the form of ventricular anodal strength-interval curves to the types of arrhythmias induced by trains of low-intensity stimuli was studied in 16 dogs. Strength-interval curves were determined after basic atrial driven beats and after induced premature ventricular depolarizations. The test stimuli for these determinations were 2-msec anodal square waves delivered in 1-msec de...
متن کاملThe differences in atrioventricular conduction of premature beats in young and adult goats.
Atrioventricular (AV) conduction was studied in anesthetized, open-chest, 1-35-day-old goats. Atrial, bundle of His, and ventricular bipolar electrograms were recorded, and the functional refractory periods of the AV conduction system and the ventricles were determined. Supraventricular premature excitation invaded the ventricles during their vulnerable period. This AV conduction property is di...
