Common Symptoms of Heart Rhythm Disorders and When to Get Tested
Contributed by Graham.
The heart depends on accurate electrical impulses to keep the heartbeat regular. Disruptions to these signals can create a range of conditions known as arrhythmias. Some are benign, and others can be life-threatening without treatment. It is imperative to be aware of the symptoms and when to consult a doctor. One of the most well-known symptoms is an irregular heartbeat, but there are various other symptoms to be aware of.
Palpitations and Fluttering
One of the first symptoms people notice is a feeling of fluttering, pounding or racing in the chest. Palpitations may last for seconds or minutes, and occur with little to no warning. While occasional palpitations may be caused by stress, caffeine or lack of sleep, persistent or worsening episodes should be evaluated by a professional. Monitoring how often and how long these sensations occur helps doctors determine if a rhythm disorder is present.
Dizziness and Light-Headedness
Disrupted heart rhythms can mean that the brain does not get enough blood to function correctly and can cause dizziness or a feeling of being light-headed. These episodes can disrupt daily activities and may be a warning that the heart is not pumping effectively. Although there are many causes of dizziness, when it is accompanied by palpitations or other symptoms, further testing may be necessary.
Fainting or Near-Fainting
Sudden loss of consciousness, called syncope, may result when the heart is unable to maintain stable circulation. Even fainting episodes that last only a few minutes should not be ignored, especially if they occur during exertion. Near-fainting, in which a person feels like they are about to faint but does not, may also be a sign of an underlying rhythm disorder. Because these symptoms may indicate serious conditions, medical evaluation is strongly recommended.
Chest Discomfort and Pain
An irregular heartbeat sometimes causes tightness, pressure, or pain in the chest. These sensations can resemble the symptoms of angina or heart attack. Any new or unexplained chest pain should be looked at by a healthcare professional as it can be a sign of many heart issues, including arrhythmia. Early detection can help slow down or prevent heart issues from getting worse.
Fatigue and Reduced Exercise Tolerance
Heart rhythm disorders may also lead to fatigue or loss of stamina. When the heart is not pumping efficiently, the body receives less oxygen, which causes exhaustion even after minor activity. Some people experience a decrease in exercise tolerance, finding they tire much more quickly than before. While these changes may develop slowly, they can be important clues to an underlying cardiac issue.
When to Seek Medical Advice
Symptoms such as palpitations, fainting or unexplained chest discomfort should never be ignored.People experiencing these signs should book an appointment with their GP, who can provide an initial assessment and, if necessary, refer them to a cardiologist. Prompt and proactive action when experiencing these symptoms can help minimise the risk of complications and ensure that treatment starts as soon as it is needed.
Managing and Treating Detected Arrhythmias
Treatment depends on the type and severity of the rhythm disorder. Some patients will need only to be monitored, while others may benefit from medication to help manage heart rate and rhythm. For more severe cases, people may require catheter ablation or need to get a pacemaker. Lifestyle changes such as avoiding caffeine, limiting alcohol, and stress management can also help promote heart health.
Staying Alert to Warning Signs
Heart rhythm disorders range in severity, but it's important to recognise the symptoms early. Palpitations, dizziness, fainting, chest discomfort and fatigue are all serious symptoms that require medical attention, especially if they are severe and persistent. Seeking professional medical advice as soon as possible can help ensure proper treatment, prevent conditions from worsening and maintain long-term heart health.
