Types of Palpitations

Atrial Fibrillation
Atrial Fibrillation

During atrial fibrillation, the upper chambers of your heart have an irregular beat, and quiver like a bowl of Jell-O. Your blood pools there, and it gets harder to pump it out to the rest of your body. When palpitations are from this condition, they often last longer than those brought on by anxiety.

Atrial Flutter

Atrial flutter is an uncommon arrhythmia but is associated with certain medical conditions such as heart failure, heart disease, alcoholism, diabetes, thyroid disease, or chronic lung disease. The best way to prevent atrial flutter is to try and avoid developing these medical conditions in the first place.

Premature Atrial Contractions
Premature Atrial Contractions

Atrial premature complexes (APCs) are a common kind of heart arrhythmia characterized by premature heartbeats originating in the atria. Another name for atrial premature complexes is premature atrial contractions. One of the most common symptoms of APCs is heart palpitations or unusual awareness of your heartbeats.

Premature Ventricular Contractions (PVCs)
Premature Ventricular Contractions (PVCs)

Patients with frequent premature ventricular contractions such as bigeminy (every other heartbeat is a premature ventricular contraction), couplets (two consecutive premature ventricular contractions), or triplets (three consecutive premature ventricular contractions) often report no symptoms.
