ventricular contraction

Ventricular contraction rate is thus reduced by 15-40 beats per minute.

This can be seen most dramatically in the case of premature ventricular contraction.

The rate was again steady for several minutes followed by three premature ventricular contractions in a row.

At first it was only one premature ventricular contraction followed by a compensatory pause.

It prevents the backflow of blood into the right atrium during ventricular contraction.

Digoxin can also strengthen ventricular contractions so that the heart is able to pump more blood with each beat.

"She didn't fibrillate but she did have premature ventricular contractions.

Then a premature ventricular contraction appeared.

This effect leads initially to bigeminy: regular ectopic beats following each ventricular contraction.

For example, some cases of premature ventricular contraction have a mitral-valve prolapse which can be determined through the physical examination.

This increases the likelihood of a premature ventricular contraction occurring during the recording period and is therefore more useful in diagnosis.

When looking at an electrocardiograph premature ventricular contractions are easily spotted and therefore a definitive diagnosis can be made.

Catecholamines will increase the heart rate and increase the strength of ventricular contraction, directly increasing cardiac output.

During ventricular contraction, the wave of depolarization moves from endocardial to epicardial surface.

A single case of premature ventricular contractions appeared causally linked to administration of modafinil.

Fagel said that 27 percent of Gathers's heart beats during exercise were of a type called premature ventricular contractions.

Cardiac output, therefore, would be expected to increase due to enhanced stroke volume, with an uncompromised filling time and a more powerful ventricular contraction.

Ventricular contraction begins at the apex of the heart, progressing upwards to eject blood into the great arteries.

Premature ventricular contractions can occur in a healthy person of any age, but are more prevalent in the elderly and in men.

Premature ventricular contractions (PVCs) often cause this feeling.

Premature ventricular contractions (PVCs) are heartbeats that occur earlier than they should.

After these first symptoms, the heart may be affected by tachyarrhythmia, bradyarrhythmia, premature ventricular contractions, or atrioventricular blockage.

Treatment of ventricular tachyarrhythmias and premature ventricular contractions can be achieved by lidocaine treatment.

The premature ventricular contraction causes early emptying of the left ventricle (LV) into the aorta.

Atrioventricular (AV) dyssynchrony occurs when there is a difference in timing between atrial and ventricular contractions.
