It is called bradycardia to the rhythm cardiac that results slower than the one that usually registers. In a picture of bradycardia, the sinoatrial nodule issues less than sixty beats per minute .
It should be noted that the sinoatrial node is called the structure where the electrical impulse that causes the heartbeat is born. If the sinoatrial node does not work, the task is assumed by the atrioventricular nodule . This second nodule usually generates between forty five and fifty-five beats per minute , a figure that also implies bradycardia.
It can be said, therefore, that bradycardia appears when the sinoatrial node emits less beats per minute than normal or when the atrioventricular node assumes the function of producing the electrical impulse but with reduced heart rate.
The origin of bradycardia is found in the interruption of electrical impulses which, in a normal situation, regulate the rhythm of the beats. This failure may be due to a disease congenital ; damage or infection of heart tissues; hypertension (high blood pressure); hemochromatosis (excess iron); hypothyroidism; lupus; or a low body temperature, for example. Certain medications can also generate bradycardia.
It is important to keep in mind that bradycardia can be a symptom of a heart disease or of one brain injury . Once bradycardia is detected, the doctor must perform a thorough evaluation to discover its cause as it can reveal the existence of a congenital disorder or an infection, to name two possibilities. If the patient in question is an athlete, knowing the cause of bradycardia can save his life because certain congenital diseases prevent the performance of intense physical activity.
One of the most effective tips to prevent bradycardia is to lead a life fury , eliminating harmful foods, exercising regularly, controlling body weight, cholesterol and blood pressure, avoiding tobacco and excess alcohol. These are some of the points to consider, but they all reduce the risk of almost any heart disease.
That said, not all patients can or should receive the same treatment for bradycardia, it depends on a number of factors, such as the cause of the slow heart rate, the severity of symptoms and the kind of electrical conduction problem. When bradycardia appears as a consequence of an underlying disorder, such as obstructive sleep apnea or hypothyroidism, then treating this problem may be enough to solve the other.
It is important to highlight that certain medications can cause bradycardia, and among them are some of those used to fight other heart diseases. In a case like this, the doctor can indicate to the patient alternative drugs after a careful evaluation. For example, slow heart rate can be corrected in this way or even by reducing the dose . If it is not possible to resort to another treatment, then there is a need for a pacemaker.
The pacemaker is a device that is located under the collarbone through an operation. For its operation you need a constant supply of energy, which you get from the batteries. The implant also contemplates the placement of a series of cables that pass through the veins and reach the heart, where they join the woven with the help of small electrodes.
Many bradycardia patients should turn to the pacemaker as part of their treatment. This device has the task of generating electrical impulses and controlling the heart rate at a level considered adequate for the proper functioning of the organism. Almost all pacemaker models can also collect and register data which, later, doctors use during controls. Follow-up appointments should be scheduled regularly.
