Causes of heart rhythm problems. Heart rhythm problems happen when there's a fault with the electrical system that makes your heart beat. This can be the result of a heart rhythm condition, such as atrial fibrillation or supraventricular tachycardia (SVT).

An arrhythmia is an abnormal heart rhythm. Your heart is controlled by a conduction system which sends out electrical impulses. This causes a heartbeat. Arrhythmias are caused by a problem in this conduction system, which can make your heart beat too slowly, too quickly, or in an irregular way. There are different types of arrhythmia, the most comm...
The symptoms you have depend on what type of arrhythmia you have. The most common symptoms include: 1. palpitations(a thumping or fluttering sensation in your chest) 1. dizziness 2. feeling as if you may ‘black out’ 3. breathlessness 4. chest discomfort 5. feeling tired.
You should speak to your GP about your symptoms if: 1. your palpitations last a long time, don't improve or get worse 2. you have a history of heart problems 3. you're concerned about the palpitations. You should dial 999 for an ambulance if: 1. along with palpitations, you start to feel short of breath, have chest pain or feel faint or dizzy.
Some underlying conditions which could cause an arrhythmia are: 1. a heart attack 2. heart failure 3. cardiomyopathy 4. coronary heart disease. Some abnormal heart rhythms can be caused by inherited conditions, such as Long QT syndrome, Brugada syndrome, CPVT and PCCD. If this is the case for you, your doctor will talk to you about having family me...
Your GP might refer you for tests including: 1. an ECG 2. an echocardiogram 3. an electrophysiological (EP) study. An ECG may include different tests such as a 24hr ECG, exercise ECG, and an implantable loop recorder. Information on what these tests are and what to expect can be found above on our ECG page.
Your treatment will depend on your type of arrhythmia. Common treatments include: 1. medication 2. cardioversion 3. catheter ablation 4. inserting an implantable cardioverter defibrillator (ICD) or pacemaker.
Most arrhythmias are manageable. This means that with the right treatment you can carry on living as you were before you were diagnosed. Living with an abnormal heart rhythm can be emotionally challengingfor you and your family. It's important to manage anxiety and stress and get support from your GP or loved ones if needed. You might have to think...
- Lifestyle triggers. Common triggers of heart palpitations include: strenuous exercise. not getting enough sleep. drinks containing caffeine, such as coffee, tea and energy drinks.
- Emotional or psychological triggers. Heart palpitations are also often caused by emotions or psychological issues, such as: excitement or nervousness. stress or anxiety.
- Medicines. Palpitations can occasionally be triggered by some medicines, including: asthma inhalers, such as salbutamol and ipratropium bromide. high blood pressure (hypertension) medicines, such as hydralazine and minoxidil.
- Hormone changes. Heart palpitations in women can sometimes be the result of hormonal changes that happen during: periods. pregnancy. the menopause. In these cases, the palpitations are usually temporary and not a cause for concern.
Dec 15, 2023 · In tachycardia, an irregular electrical signal, called an impulse, starts in the upper or lower chambers of the heart. This causes the heart to beat faster. Tachycardia (tak-ih-KAHR-dee-uh) is the medical term for a heart rate over 100 beats a minute.
Sep 12, 2024 · Abnormal heart rhythms, or arrhythmia (also called irregular heartbeats), occur when the heart beats too fast, too slow, or irregularly, disrupting its normal function. They can be asymptomatic or cause noticeable symptoms, such as palpitations, dizziness, or shortness of breath.
Supraventricular tachycardia (SVT) happens when the electrical system that controls your heart rhythm is not working properly. This causes your heart to suddenly beat much faster. It can then slow down abruptly. A normal resting heart rate is 60 to 100 beats per minute (bpm).
Oct 13, 2023 · This rapid, irregular heart rate starts with faulty electrical signals in the lower heart chambers, called the ventricles. The rapid heart rate doesn't let the ventricles properly fill with blood. So the heart may not be able to pump enough blood to the body.
