Fortunately the human heart has a couple of backup mechanisms that can help the heart in case of severe bradycardia. These escape mechanisms can occur in every part of the heart (i.e. atrium, AV, node, ventricle). In general, the rate of the escape mechanism is faster when the escape rhythm is located higher in the conduction system. | |||
To understand the pathophysiologic basis of most conduction disorders or disorders of impulse formation it is important to understand the physiology of cardiac conduction and mechanisms of arrhythmia as detailed in the general cardiac arrhythmia section [Link]. | To understand the pathophysiologic basis of most conduction disorders or disorders of impulse formation it is important to understand the physiology of cardiac conduction and mechanisms of arrhythmia as detailed in the general cardiac arrhythmia section [Link]. | ||
