Common Symptoms of Arrhythmia

Arrhythmia can present a wide range of symptoms, varying from mild to severe. The specific manifestations depend on the type and severity of the condition. Below is a detailed overview of the possible symptoms:

Mild Symptoms of Arrhythmia

Some individuals may not experience any noticeable symptoms at all. In such cases, arrhythmia may only be detected during a routine physical examination when a doctor listens to the heart with a stethoscope and notices irregularities such as skipped beats or premature contractions. Others may report non-specific or atypical symptoms, including chest tightness, heart discomfort, palpitations, or a sensation of the heart skipping a beat. Some people may also feel unusually tired, fatigued, or weak. In children, arrhythmia might manifest as a fluttering or throbbing sensation in the chest or a heightened awareness of the heartbeat.

Severe Symptoms of Arrhythmia

In more serious cases, patients may experience episodes known as Adams-Stokes syndrome, or cardiac syncope. This typically occurs when the heart rate becomes dangerously fast or slow, leading to significant changes in blood flow and potentially causing a temporary lack of oxygen or blood supply to the brain. These episodes can result in fainting, seizures, or sudden loss of consciousness. In the most extreme cases, certain types of arrhythmia can lead to sudden cardiac death, sometimes without prior warning signs.

Diagnostic Recommendations

When symptoms of arrhythmia occur, it is crucial to obtain a standard 12-lead electrocardiogram (ECG) as soon as possible for accurate diagnosis. In some cases, a 24-hour Holter monitor may be necessary to capture intermittent rhythm abnormalities. For patients with a family history of sudden cardiac death or unexplained fainting episodes, long-term monitoring using an implantable cardiac monitor may be recommended. This device can continuously record heart activity for several months or even years, helping doctors detect and manage arrhythmias at an early stage.
