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).
Normal heartbeat. Tachycardia is caused by something that disrupts the normal electrical impulses that control the rate of your heart's pumping action. Many things can cause or contribute to problems with the heart's electrical system.These factors include: 1  Damage to heart tissues from heart disease. Ventricular tachycardia. 2  Ventricular tachycardia is a rapid heart rate that originates with abnormal electrical signals in the ventricles. 3  The rapid heart rate doesn't allow the ventricles to fill and contract efficiently to pump enough blood to the body.
