The experience of increased heart rate can happen to all people and at any age.... Abnormal heartbeat is called cardiac arrhythmia.... But in some cases, a person should be sensitive to this increase in heart rate....

What is cardiac arrhythmia?... A cardiac arrhythmia is a condition in which the heart beats irregularly, known as palpitations, or is too slow or too fast than normal. - Slow heart rate or bradycardia: heart rate less than 60 beats per minute - Fast heart rate or tachycardia: heart rate more than 100 beats per minute - Irregular heartbeat (fibrillation) Most cardiac arrhythmias are not severe and serious, but in some cases they may cause a stroke or cardiac arrest... It should be noted that not all tachycardias or bradycardias mean the presence of heart disease... For example, when exercising, the heart rate increases to receive enough oxygen... The heart has four chambers and the two lower chambers are called the ventricles... The heart rhythm is controlled by a natural pacemaker located in the right atrium and called the sinus node... The node of electrical messages initiates each beat.. The job of the AV node is to slow down the electrical messages before they are transmitted to the ventricles.. Because of this, the electrical messages with this optical delay allow the ventricles.. to have enough time to fill with blood.. In a normal process, the heart beats between 60 and 100 times per minute.. Cardiac arrhythmia is classified based on the change it causes in the heartbeat. The types of arrhythmias are: tachycardia A heart rate of more than 100 beats per minute is called bradycardia It is called a heart rate less than 60 times per minute.... But in these cases, you should note that not all tachycardia or bradycardia indicate heart disease.... For example, when we exercise, the heart rate increases.... So that enough oxygen is provided to the tissues of the body... Also, the heart rate decreases during sleep... Causes of cardiac arrhythmia Any disturbance in the impulses of the heart that stimulate the contractions of the heart can lead to cardiac arrhythmia. Cardiac arrhythmia is caused by improper functioning of the electrical impulses that coordinate the heartbeat. Several factors can cause improper functioning of the heart, including: - Alcohol abuse - Diabetes - Drinking too much coffee - Drug use - Heart diseases such as heart failure - High blood pressure - Stress - Hyperthyroidism - cigarettes - Taking some food and herbal supplements - Taking some medications - Changes in the structure of the heart, for example due to cardiomyopathy A person with a healthy heart rarely experiences long-term cardiac arrhythmias unless an external trigger such as medication or cardiac shock is involved. As a result, the presence of any heart problem means that electrical impulses do not pass through the heart properly, which can increase the risk of cardiac arrhythmias. People with a history of severe arrhythmias may have no symptoms, while some with no symptoms may have severe arrhythmias... Symptoms of arrhythmias depend on the type of arrhythmia as follows: **symptoms of slow heart rate (bradycardia):** - Chest pain - Impaired concentration - Distress and confusion - Difficulty exercising more than usual - Dizziness - Fatigue - Lightheadedness - Heart palpitations - shortness of breath - Fainting or symptoms close to it - Excessive sweating **Symptoms of fast heartbeat (tachycardia):** - Panting - Dizziness - Fainting or symptoms close to it - Chest shaking - Chest pain - Lightheadedness - Sudden weakness **Symptoms of irregular heartbeat (fibrillation):** - Panting - Dizziness - Heart palpitations - Fainting or symptoms close to it - Weakness Treatment of cardiac arrhythmia Cardiac arrhythmia treatment usually leads to control of slow, fast and irregular heartbeat.... Cardiac arrhythmia treatment is necessary when the person's condition is worsening or the person has severe symptoms.... Different arrhythmias have different treatments... - Treatment of slow heart rate (bradycardia) If the slow heart rate is caused by an underlying disease, the doctor will first treat the underlying disease. If there is no underlying disease, the doctor may suggest the installation of a pacemaker (tachycardia). There are several ways to treat a fast heartbeat: - Vagal maneuvers: Certain movements and exercises that a person can do at home may stop some arrhythmias that start in the lower half of the heart. - Cardiac defibrillation and implantable cardiac defibrillators (ICD): This is a method of converting an abnormal heartbeat into a normal heartbeat through a small electric shock... - Surgery **symptoms of cardiac arrhythmia** Cardiac arrhythmias have various complications, which include: Stroke: Cardiac arrhythmia increases the possibility of blood clot formation. As a result of breaking this clot and transferring it from the heart to the brain, there is a possibility of stroke. The following may increase the risk of cardiac arrhythmia in people: - **65 years old and above** - **Genetic and hereditary diseases** - **Underlying heart problems** - **hypothyroidism or hyperthyroidism** - **Consumption of some prescription drugs and non-prescription drugs** - **blood pressure** - **Obesity** - **uncontrolled diabetes** - **High and regular consumption of alcohol** - **excessive caffeine consumption** Given that some of these are unavoidable, a person can take small steps to reduce the risk of heart arrhythmia by making lifestyle changes, including being active, avoiding heavy and regular alcohol consumption, and limiting caffeine consumption.
