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).
This is because frequent premature ventricular contractions can diminish the ability of the heart to pump blood to the other organs (diminished cardiac output), resulting in low blood pressure. Patients with three or more consecutive premature ventricular contractions in a row have ventricular tachycardia. Ventricular tachycardia that is prolonged can result in low cardiac output, low blood pressure, and fainting (syncope).
