Arrhythmia refers to an abnormal heart rhythm characterised by irregular or erratic beating of the heart. Normally, the heart beats in a regular, coordinated rhythm, pumping blood efficiently throughout the body. However, in arrhythmia, this rhythm is disrupted, leading to irregular heartbeats that may be too fast (tachycardia), too slow (bradycardia), or irregular. Arrhythmias can occur in the upper chambers (atria) or lower chambers (ventricles) of the heart and may be harmless or potentially life-threatening, depending on their type and severity (1). Common types of arrhythmias include atrial fibrillation, ventricular tachycardia, and atrial flutter.

Heart arrhythmia can manifest in various ways, often causing palpitations, a sensation of fluttering or rapid heartbeat. Other common heart arrhythmia symptoms include dizziness, fainting, chest discomfort, shortness of breath, fatigue, and lightheadedness (1). These symptoms may vary in severity and frequency, and some individuals may not experience any noticeable symptoms at all, making regular check-ups and screenings essential for early detection and intervention.

Heart arrhythmias vary in severity, with some causing minor discomfort and others posing significant health risks. While occasional irregular heartbeats may not be cause for concern, persistent or frequent arrhythmias can lead to complications such as blood clots, stroke, heart failure, or sudden cardiac arrest. The seriousness of a heart arrhythmia depends on various factors, including the underlying cause, the frequency and duration of abnormal heart rhythms, and the individual’s overall health status. Prompt medical evaluation and appropriate management are crucial in determining the potential risks associated with a heart arrhythmia and implementing interventions to mitigate these risks effectively (1). It’s essential for individuals experiencing heart arrhythmia symptoms of heart arrhythmia to seek medical attention promptly to receive an accurate diagnosis and develop a personalised treatment plan tailored to their specific needs.

Understanding the irregular heartbeat causes is key to managing heart arrhythmia effectively. While the condition can occur in individuals without any underlying heart issues, it’s often associated with factors such as coronary artery disease, high blood pressure, thyroid disorders, electrolyte imbalances, congenital heart defects, and previous heart attacks (3). Lifestyle choices like excessive alcohol consumption, smoking, illicit drug use, and high levels of stress can also contribute to heart rhythm disturbances.

Diagnosing heart arrhythmia typically involves a series of tests and evaluations to assess heart function and rhythm. These may include an electrocardiogram (ECG or EKG), Holter monitor, event monitor, stress test, echocardiogram, or electrophysiology study (3). Continuous monitoring may be necessary to capture intermittent arrhythmias and assess their severity accurately. Regular check-ups with a healthcare professional are essential for monitoring heart health, evaluating treatment effectiveness, and adjusting treatment plans as needed.

Treatment aims to restore normal heart rhythm, alleviate heart arrhythmia symptoms, and reduce the risk of complications. Depending on the severity and underlying causes of the arrhythmia, treatment options may include medication therapy, such as antiarrhythmic drugs or blood thinners, to prevent blood clots. In some cases, procedures like catheter ablation, cardioversion, or implantation of a pacemaker or implantable cardioverter-defibrillator (ICD) may be recommended to regulate heart rhythm and prevent life-threatening arrhythmias (4).

In some cases, heart arrhythmia symptoms may resolve on their own without intervention. For instance, transient arrhythmias triggered by factors like stress, caffeine, or certain medications may subside once the underlying trigger is removed or managed. Additionally, occasional irregular heartbeats may not necessarily indicate an underlying heart condition and may resolve spontaneously (2). However, persistent or recurrent arrhythmias often require medical evaluation and treatment. Depending on the underlying cause and severity of the arrhythmia, treatment options may include medication therapy, lifestyle modifications, or medical procedures.

While some risk factors for heart arrhythmia cannot be modified, several lifestyle modifications can help prevent or manage the condition. Maintaining a heart-healthy diet rich in fruits, vegetables, lean proteins, and whole grains, along with regular exercise, can improve cardiovascular health and reduce the risk of arrhythmias. Managing stress, maintaining a healthy weight, avoiding tobacco use, limiting alcohol and caffeine intake, and following a prescribed treatment plan for underlying health conditions are also important preventive measures (2).

Heart arrhythmia is a complex condition that requires careful management and monitoring. By recognising heart arrhythmia symptoms, understanding the causes, and adopting preventive strategies, individuals can take proactive steps to safeguard their heart health. Regular consultations with healthcare professionals and adherence to prescribed treatment plans are essential for effectively managing heart arrhythmia and reducing the risk of complications.
