Pathophysiology of Cardiac Causes of Tachycardia. Cardiac causes of tachyarrhythmias may either be a result of disturbance in the formation of an electrical impulse (i.e. abnormality of the sinoatrial node) or an alteration of the conduction of the same (e.g. bundle branch block, Wolf-Parkinson-White syndrome).
The heart rate (HR), as well as the stroke volume (SV) â volume of blood ejected from the heart with each contraction â both directly affect the cardiac output: CO=HR ÃSV; The major problem with cardiac dysrhythmias is that they alter the cardiac output. In the case of tachyarrhythmias, the heart is beating too fast to allow adequate filling of the ventricular chambers. Consequently, it is unable to eject sufficient blood to supply the organs of the body (especially the brain, kidneys and lungs).
