The feeling of an arrhythmia may feel like fluttering or a racing heart, and it may not be harmful. However, some arrhythmias can cause distressing and sometimes even life-threatening signs and symptoms.
It may be normal, however, to have a fast or slow heart rate. For example, your heart rate may increase with exercise or slow while you sleep.
Treatment for arrhythmias can include medications, catheter procedures, implanted devices, or surgery to control or eliminate a fast, slow, or irregular heartbeat. A heart-healthy lifestyle can help prevent the heart from damage that can cause certain types of arrhythmias.
species
Arrhythmias are generally classified according to the speed of the heartbeat. For example:
Tachycardia, which is an increased heart rate. The resting heart rate is more than 100 beats per minute.
Bradycardia, which is a slowing of the heartbeat. The resting heart rate is less than 60 beats per minute.
fast heartbeat (tachycardia)
Types of tachycardia include:
atrial fibrillation. Disruption of heart signals causes the heart to beat faster and irregularly. This condition may be temporary, but some episodes of atrial fibrillation do not stop without treatment. Atrial fibrillation is associated with serious complications such as stroke.
flutter Atrial flutter is similar to atrial fibrillation, but with flutter, the heartbeat is more regular. Atrial flutter is also associated with stroke.
Supraventricular tachycardia. tachycardia is a broad term for a heart rhythm disorder that begins above the heart’s two lower chambers (ventricles). Supraventricular tachycardia causes episodes of heart palpitations that begin and end suddenly and rapidly.
slow heartbeat (bradycardia)
Although a heart rate below 60 beats per minute at rest is considered bradycardia, a low resting heart rate does not always indicate a problem. And if you’re in good physical shape, your heart may still be able to pump enough blood to your body at less than 60 beats per minute at rest.
But if you have a slow heart rate and it’s not pumping enough blood, you may have a type of bradycardia. Types of bradycardia include:
Sick sinus syndrome. The sinus node is the part responsible for regulating the heart rate. If there is an abnormality in its functioning, the heart rate may alternate between too slow (bradycardia) and too fast (tachycardia). Scarring near the sinus node can also cause sick sinus syndrome, slowing or blocking the transmission of electrical impulses. Sick sinus syndrome is more common among older adults.
Premature heartbeat
One-time extra beats, sometimes occurring in alternating patterns with a normal heartbeat. Premature impulses may come from the upper chamber of the heart or the lower chamber of the heart .
An early beat may look as if the heart has missed a beat. These extra heartbeats are generally not a cause for concern and rarely indicate that you have a more serious condition. However, an early pulse can cause a longer-lasting arrhythmia, especially in patients with heart disease. The recurrence of an early pulse and its persistence for several years may lead to a weak heart.
symptoms
Arrhythmias may not cause any signs or symptoms. A doctor may notice an irregular heartbeat while examining you for another health condition.
Signs and symptoms of an arrhythmia in general may include:
Flutter in the chest
Rapid heartbeat (tachycardia)
slow beat (slowing of the heartbeat)
chest pain
shortness of breath
Other symptoms may include:
anxiety
exhaustion
lightheadedness or dizziness;
Sweating
Loss of consciousness (fainting), or approaching loss of consciousness
When do you see a doctor?
If you feel like your heart is beating too fast or too slow, or if it misses a beat, make an appointment to see a doctor. Seek immediate medical help if you experience shortness of breath, weakness, dizziness, lightheadedness, fainting or near-fainting, and chest pain or discomfort in the chest.
A type of arrhythmia, called ventricular fibrillation, can cause your blood pressure to drop too low. This decrease may occur within seconds, and soon the person’s pulse and breathing will stop. If this occurs, the following steps should be taken:
Call 911 or call the emergency number in your area.
the reasons
To understand the causes of arrhythmias, it can be helpful to know how the heart normally works.
How does the heart beat?
The heart is made up of four chambers: two upper chambers (the atria) and two lower chambers (the ventricles).
Normally, the heart’s rhythm can be controlled by a natural pacemaker (called the sinus node) in the right upper chamber (atrium). The atrial node sends electrical signals that cause the heart to start beating normally. These electrical signals travel through the atria, causing the heart muscle to contract (contract) and pump blood into the ventricles.
risk factors
Factors that may increase your risk of developing an arrhythmia include:
Coronary artery disease and other heart problems and previous heart surgeries. Narrowed heart arteries, heart attack, abnormal heart valves, previous heart surgery, heart failure, cardiomyopathy and other heart-damaging conditions are risk factors for most types of arrhythmias.
Hypertension. This condition increases the risk of coronary artery disease. They may also cause the walls of the left ventricle to become stiff and thicken, which changes the way electrical impulses travel through the heart.
Congenital heart disease. Having a congenital heart disease may affect the heart rhythm.
Thyroid disease. Having an overactive or underactive thyroid gland may increase your risk of developing an arrhythmia.
complications
Complications depend on the type of arrhythmia. In general, complications of arrhythmias may include stroke, sudden death, and heart failure.
protection
Lifestyle changes that reduce the risk of heart disease can help prevent arrhythmias. A heart-healthy lifestyle includes:
A heart-healthy diet
Maintain physical activity.
Maintain a healthy weight.
Non-smoking
