The heart is the central organ of the circulatory system and its mechanism is very complex. When the heartbeat is irregular, it is called arrhythmias or heart rhythm disorders.
The heart is located in the center of the chest between the two lungs and slightly inclined to the left. One can easily understand that at the slightest failure of its operation, serious consequences occur for health. Among the many heart diseases, heart rhythm disorders are issues that should not be neglected.
Beats of the human heart
Each beat of the heart is naturally done throughout our lives, without one can really realize. The frequency of heartbeat varies from one person to another, but averages between 60 and 80 beats per minute. This is called heart rate. The heart muscle consists of four cavities and performs its work by contracting with each electrical pulse. The pulsations are triggered by a natural stimulator located in the center of the four cavities. At each pulse, the blood is delivered to the two lower chambers (ventricles) and the upper ones (atria), ensuring the distribution of blood throughout the body.
It is called cardiac arrhythmias (irregular beats) when the synchronism of the pulsations between the atria and the ventricles is disturbed. An arrhythmia can be manifested in two ways either by bradycardia or tachycardia. Bradycardia is a lack of electrical pulsations that lower the pulse rate below 60 beats per minute. In the case of tachycardia, it is the contrary situation, the electric pulsations exceed 100 beats per minute.
Bradycardia, therefore, slows the heart rate and blood can not reach the whole body. Tachycardia increases the heart rate, the blood circulates too quickly between the cavities and can cause the formation of a blood clot.
Transient arrhythmia is not a threat to health. Sometimes stress or consuming too much caffeine or alcoholic beverages increases the heart rate. By eliminating these causes, the problem usually goes away naturally. However, it is important to consult a doctor when an arrhythmia continues for a few days or if discomfort is felt.
Symptoms of arrhythmias
The symptoms are different for each person. They can vary depending on the condition of a person’s heart and the severity of the arrhythmia. A great fatigue (chronic) that persists even after rest is the first symptom. Shortness of breath and dizziness may occur as well as loss of consciousness in some cases. These symptoms are typical for bradycardia.
The person who suffers from tachycardia will feel very fast and very irregular heartbeats in his chest and neck area. His general condition will be very uncomfortable. The person will experience dizziness, weakness, sweating, and often these symptoms will be accompanied by chest pain. It is important to see a doctor as soon as possible, in both types of arrhythmias.
Causes and treatments
Congenital malformations, aging, certain medications, and certain diseases can cause heart arrhythmia. Bad lifestyle habits can also be the cause. To treat the problem, medications are prescribed to restore a regular heartbeat. In more serious cases, the installation of a pacemaker will be necessary. In addition to these interventions, it will be recommended to have a good lifestyle, to exercise and avoid stress to the extent possible or to be able to manage it well.
