Palpitations: Causes, Symptoms, and Treatment

1. Introduction Heart palpitations are the conscious, often distressing awareness of one’s own heartbeat, frequently described as a fluttering, racing, or pounding sensation within the chest. The most common causes include benign premature contractions, supraventricular tachycardias, and systemic metabolic triggers such as hyperthyroidism. Effective management relies on capturing the specific electrical anomaly on an electrocardiogram … Read more

What does it mean when your heart rhythm feels irregular for a few seconds?

1. Introduction When your heart rhythm feels irregularly paced for a few seconds, it usually indicates a premature ventricular contraction or a premature atrial contraction. These extra electrical signals cause the heart to pause momentarily and beat more forcefully on the next cycle, creating a sudden fluttering sensation. For the vast majority of individuals, these … Read more

What Does a Sudden Irregular Heartbeat That Takes Your Breath Away Indicate?

1. Introduction A sudden irregular heartbeat that takes your breath away strongly indicates a cardiac arrhythmia, such as premature ventricular contractions, supraventricular tachycardia, or atrial fibrillation. When the heart’s electrical conduction system misfires, the cardiac muscle contracts out of sync, temporarily diminishing the volume of oxygenated blood pumped to the lungs and brain. This sudden … Read more

How to Tell if an Irregular Heartbeat is Harmless or an Arrhythmia?

1. Introduction A harmless irregular heartbeat typically involves isolated, brief skipped beats or flutters that occur during periods of rest and resolve entirely without causing any accompanying systemic distress. An arrhythmia of clinical concern presents as a sustained, chaotic racing or profoundly slow rhythm that is overwhelmingly accompanied by severe shortness of breath, profound dizziness, … Read more
