A right bundle branch block ( RBBB) is a heart block in the right bundle branch of the electrical conduction system. [1] During a right bundle branch block, the right ventricle is not directly activated by impulses traveling through the right bundle branch. However, the left bundle branch still normally activates the left ventricle.
Right axis deviation. The electrical axis of the heart is the net direction in which the wave of depolarization travels. It is measured using an electrocardiogram (ECG). Normally, this begins at the sinoatrial node (SA node); from here the wave of depolarisation travels down to the apex of the heart. The hexaxial reference system can be used to ...
Bainbridge reflex. The Bainbridge reflex or Bainbridge effect (also called the atrial reflex) is a cardiovascular reflex causing an increase in heart rate in response to increased stretching of the wall of the right atrium due to increased filling of the right atrium with venous blood. It is detected by stretch receptors embedded within the ...

Cardiac ventriculography is a medical imaging test used to determine a person's heart function in the right, or left ventricle. [1] Cardiac ventriculography involves injecting contrast media into the heart's ventricle (s) to measure the volume of blood pumped. Cardiac ventriculography can be performed with a radionuclide in radionuclide ...
