We talked in an article before about the natural slowing of the heartbeat that can occur in a normal physiological manner, and today we will talk about the slowing of the heartbeat that is the result of a medical condition and requires treatment. In these cases, the pulse rate will be less than 60 beats per minute, and it can reach up to 20-30 beats. The slower the pulse, the more symptoms increase. One of the symptoms that accompanies a slow pulse is severe dizziness that makes the person unable to stand or focus on what is around him, and it can lead to fainting, which occurs frequently when the person stands up.
As for the reasons that lead to a slow pulse, they include:
Poor blood supply to the nodes that generate the electrical signal in the heart, whether they are the atrial or ventricular nodes, and this can occur due to atherosclerosis or a heart attack.
Fibrosis of the cells responsible for generating the electrical signal as a result of aging or chronic diseases that cause the accumulation of harmful fibers in the nodes.
External pressure on the nodes due to severe calcifications in the walls of the heart valves, or the accumulation of fluid and pus around the valves due to their proximity to the ventricular nodes.
Taking some medications that affect the atrial and ventricular nodes and slow them down in a harmful way.
