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).
Finally, junctional ectopic tachycardia (JET) is a rare tachycardia caused by increased automaticity of the AV node itself initiating frequent heart beats. On the ECG, junctional tachycardia often presents with abnormal morphology P-waves that may fall anywhere in relation to a regular, narrow QRS complex.
