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).
There is an eclectic collection of causes of tachyarrhythmias. 1  It may be easier to think of these causes as those originating outside the heart (non-cardiac) and those caused by a disease process within the heart (cardiac). However, the specific cause of the tachyarrhythmia (if one exists) is often dependent on the type of tachyarrhythmia the patient has.
