All About Cardiovascular System and Disorders

When heart contracts, blood is pushed into the blood vessels through the aorta from the left ventricle. This increases the blood pressure at that time.

EVOLVO study found that remote monitoring of defibrillators is useful in terms of reducing ER visits, total health care usage and better quality of care.

Dyeless angiography is possible with magnetic resonance imaging where the signals from the moving hydrogen particles in blood give the image.

Many of the cardiac arrhythmias can be worsened with psychological stress.

Defibrillator abolishes disorganized electrical activity of the heart by giving a high voltage shock so that the heart restarts on its own in normal rhythm.

Only some unfortunate victims of heart attack die suddenly, while many survive to reach hospital and lead near normal lives after discharge.

Supraventricular ectopics can mimic a ventricular ectopic when there is aberrant ventricular conduction either pre-existing or phasic.

Myocardial infarction is the medical name for heart attack. It is damage to a region of heart muscle due to abrupt cessation of blood supply to that region.

Cryoablation is a method used to treat heart rhythm disorders by freezing the abnormal region using a cryoprobe.

RF ablation is radiofrequency catheter ablation. It is an important method to treat heart rhythm disorders.
