Palpitations And Heart Flutter: Understanding The Causes And Solutions

Palpitations refer to an uncomfortable awareness of the heartbeat, often described as a pounding or racing sensation in the chest. This common symptom in cardiology can arise from various causes. For example, individuals with hyperthyroidism often experience an intensified heartbeat, leading to feelings of anxiety and palpitations. Similarly, those suffering from chronic anemia or prolonged high fever may also feel significant cardiac discomfort.

Common Causes Of Heart Palpitations

One of the most frequent causes of palpitations is arrhythmia—abnormal heart rhythms. Tachyarrhythmias, or abnormally fast heartbeats, can lead to noticeable discomfort. Conditions such as sinus tachycardia can progress into supraventricular tachycardia, where some patients experience episodes of atrial fibrillation or flutter at night, causing sudden feelings of heart flutter and unease. On the other hand, bradyarrhythmias—slow heart rhythms—can also result in palpitations. Patients with significant conduction issues like second- or third-degree atrioventricular block often report sensations of fluttering or irregular heartbeats.

Psychological And Functional Factors

In some cases, heart palpitations may stem from psychological conditions rather than physical heart problems. Patients diagnosed with neurocardiogenic syndrome or anxiety disorders may experience palpitations due to autonomic nervous system imbalances. These functional disturbances often result from stress, anxiety, or panic attacks, which can mimic cardiac symptoms without underlying heart disease.

When To Seek Medical Help

If palpitations are frequent, persistent, or accompanied by symptoms like dizziness, shortness of breath, or chest pain, it's crucial to consult a healthcare professional. These could be signs of a more serious condition that requires diagnostic testing such as an electrocardiogram (ECG), Holter monitoring, or blood tests to identify underlying issues like thyroid dysfunction or anemia.
