Cardiac Conduction System: Function, Role & Diseases

The excitation conduction system of the heart consists of glycogen-rich specialized cardiac myocytes. They focus the contraction signals generated by the excitation generation system and transmit them to the muscles of the atria and ventricles in a specific rhythm, creating an orderly sequence of systole (beating phase of the ventricles) and diastole (relaxation phase of … Cardiac Conduction System: Function, Role & Diseases

Ventricular Replacement Rhythm: Function, Role & Diseases

Ventricular replacement rhythm is the electrical self-excitation of the ventricular muscles. When ventricular replacement rhythm occurs, the patient has a serious cardiac arrhythmia due to failure of the two upstream excitation centers, the sinus node and AV node. The body tries to ensure survival through the ventricular replacement rhythm. The ventricular beating rate is then … Ventricular Replacement Rhythm: Function, Role & Diseases
