Why is a permanent pacemaker needed? In case the heart rate slows down excessively because the warning center (sinus node) cannot generate a warning at a sufficient rate or there is any interruption in the conduction paths, pacemakers placed in the body are needed to provide the necessary heart rate for the patient to maintain

What is cardiac catheterization and angiography, why are these procedures needed? Cardiac catheterization and angiography are diagnostic methods, not treatment. It is based on imaging the heart cavities and coronary arteries during the administration of contrast material (a kind of medical dye) and taking motion pictures using “X” rays. The data obtained are very valuable

What is the electrical system of the heart? Our heart has a system similar to the electricity grid of a city. In fact, the stimuli originating from the main center (sinus node) in the right atrium, after passing through an intermediate station (atrioventricular node) located between the atria and ventricles, with a short delay, are
