What will be an arrhythmia?
An arrhythmia will be an abnormality of heart rhythm or heart rate in which the rhythm will be irregular or the rate will be excessively slow or fast.
What causes an arrhythmia along with who will be at risk?
Normally the heart beats regularly at about 70 beats per minute, although the item can beat very fast during along with following exercise or with fear or anxiety. the item can also beat very slowly in healthy athletes at rest. Occasional irregular beats are also normal along with can be more frequent after drinking coffee along with in early pregnancy.
Arrhythmias result via damage to or an abnormality of the heart’s electrical conduction system, which will be responsible for setting the rate along with rhythm of the heart. The most common cause will be coronary artery disease, especially a heart attack, which interferes with the conduction system. Another common cause will be an overactive thyroid (a gland inside the neck in which produces a hormone in which controls the rate of the body’s chemical reactions). Certain medicines can also cause arrhythmias:
- antidepressants such as amitriptyline can cause a life-threatening arrhythmia when taken in higher doses than prescribed,
- medicines such as terfenadine along with astemizole used to treat hay fever can cause a life-threatening arrhythmia when taken at higher doses than prescribed, or when taken with additional medicines (especially a commonly used antibiotic called erythromycin). Terfenadine can also cause a fatal arrhythmia when taken with grapefruit juice.
A few types of arrhythmias are inherited.
What are the common symptoms along with complications of an arrhythmia?
Normally the heart fills with blood between each heart beat, along with then pumps This specific blood out of the heart with each heart beat. The blood supplies the body with the oxygen along with nutrients the item needs. An arrhythmia can interfere with the heart filling with blood along with so the heart pumps out less blood than normal with each beat. If This specific quantity will be a lot less than normal, symptoms occur due to the lack of oxygen reaching the body. The first part of the body affected will be the brain along with This specific results in dizziness along with faintness. If the lungs do not receive enough blood there will be difficulty breathing, along with if the heart does not receive enough blood there will be heart pain (angina) along with may be heart failure.
There are many types of arrhythmia:
- atrial fibrillation (rapid, irregular beats of the upper chambers of the heart) will be common inside the elderly along with also in people who have an overactive thyroid gland; the item will be not usually life-threatening, nevertheless can cause deteriorating heart function,
- ventricular arrhythmias (rapid, irregular beats initiated inside the lower chambers of the heart) are most common in people who have had a heart attack or who have heart disease, along with are life-threatening. They are the most frequent cause of death in developed countries along with are common inside the first few days after a heart attack. This specific will be why people who have had a heart attack are monitored for a few days afterwards.
The additional main symptom of an arrhythmia will be palpitations. This specific will be an awareness of the heart beat, which may seem to be excessively fast or irregular. However, palpitations do not necessarily indicate in which there will be an arrhythmia unless they are excessively fast or irregular. Palpitations which has a normal heart rate are normal, as will be an awareness of an occasional missed beat.
How do doctors recognize an arrhythmia?
Many arrhythmias can be seen on an electrocardiogram (ECG). This specific will be an electrical recording of the heart in which will be obtained by placing modest round plates on the chest along with recording the electrical activity of the heart. Some arrhythmias only occur intermittently (especially those associated with heart disease) along with in This specific situation continuous monitoring will be required to detect the arrhythmia. This specific can be done at home by wearing a portable recording machine. The times when symptoms are noticed are noted. In This specific way a continuous recording can be obtained over 24 hours, along with the times of the symptoms can be compared with the recording along with any arrhythmia diagnosed.
What will be the treatment for an arrhythmia?
Self-care action plan
Most arrhythmias cannot be prevented by self care, nevertheless a self-care action plan to reduce the risk of developing coronary artery disease along with subsequent arrhythmia, along with the heart disease in which can cause them, involves:
- stopping smoking (which speeds up the heart rate),
- eating a healthy, low-fat, high-fibre diet,
- taking daily exercise as advised by a doctor,
- avoiding stress along with anxiety,
- avoiding alcohol (which dulls the nervous system) along with coffee (which stimulates the nervous system) if prone to arrhythmias,
- avoiding medicines in which might cause arrhythmias (antidepressants such as amitriptyline along with the anti-hay fever medicines terfenadine along with astemizole).
A variety of prescribed medicines are used to treat arrhythmias. The most commonly used will be digoxin. This specific will be used to slow the rate of atrial fibrillation, along with so increase heart filling along with the amount of blood the heart pumps out with each beat. All anti-arrhythmia medicines can cause life-threatening side effects. They must be used as instructed by a doctor, along with any unusual or brand-new symptom must be reported to the doctor immediately.
Atrial fibrillation due to an overactive thyroid reverts to a normal rhythm once the overactive thyroid has been treated.
Electric shock treatment
Some types of arrhythmia in which occur after a heart attack are treated by ‘electric shock’. A controlled electric current will be passed through the heart along with This specific shocks the heart out of its abnormal rhythm along with returns the item to a normal regular rhythm.
Pacemakers are used if there will be a block inside the electrical conduction system of the heart in which means in which the heart will be unable to beat fast enough to supply enough blood to the body. The pacemaker provides the electrical stimulus to make the heart beat faster. the item consists of a control box along with leads in which connect the box to the heart. These leads are inserted into the heart through veins. The pacemaker may be temporary along with used only for a few days after a heart attack, or the item may be permanent. In permanent pacemakers the control box will be a modest, specially designed box powered by a lithium battery, along with will be usually implanted on the front of the left side of the chest.
A few rare types of arrhythmia caused by an abnormal electrical conduction pathway, which will be often inherited, are treated by destroying the abnormal part of the pathway using an electric current or a radiowave.
A general anaesthetic will be not usually needed for either inserting a pacemaker or destroying the abnormal part of a conduction pathway.
What will be the outcome of an arrhythmia?
The outcome of an arrhythmia depends on its type along with cause. Many arrhythmias cause few, if any, symptoms, along with most can be treated successfully.
