What Can Be Mistaken For Heart Palpitations?


Just like many other complications, heart palpitations are often confused with conditions which themselves are not heart palpitations. The problem with this is that you may ignore heart palpitations yet you’re dealing with something more serious. So, it is natural to wonder, what can be mistaken for heart palpitations?

One of the most common cardiovascular issues that can be mistaken for heart palpitations is atrial fibrillation (AFib). AFib is characterized by rapid and irregular contractions of the heart’s upper chambers which also poses serious risks like stroke and heart failure if untreated.

As explained, the problem with AFib is that the symptoms often overlap with other common conditions which sometimes make it harder to tell if you’re dealing with AFib or something else. If you’re experiencing rapid, fluttering, or pounding heartbeats and not sure if you’re dealing with heart palpitations or AFib, here are a few tips to tell the difference:

1) Duration and Associated Symptoms

AFib: Palpitations due to AFib generally tend to last for extended durations longer than those caused by anxiety. If you get palpitations that are accompanied by symptoms like nausea and sweating, you may be dealing with AFib.

Palpitations: Transient and anxiety-induced palpitations may pass swiftly. They may not come with additional symptoms.

2) Use Rhythmic Analysis

AFib: The heartbeat in AFib is wildly erratic. Mostly, they show irregular and chaotic patterns.

Palpitations: While palpitations elevate the heart rate, it follows a steadier rhythm and gradually return to normal.

3) Consider the Context

AFib: Context matters if you’re not sure if you’re dealing with AFib or something else. If you’re getting palpitations in tense or anxious situations, it’s likely a response to heightened emotions.

Palpitations: Stress-induced palpitations are often a result of the brain releasing hormones. This is what may cause the temporary acceleration in heart rate.

4) Age and Health Factors

AFib: People over 65, particularly those with pre-existing heart or thyroid conditions, face a higher likelihood of AFib.

Palpitations: Occasional palpitations may occur in individuals of various ages. These incidences may be triggered by stress or external factors.

5) Monitoring Heartbeat Patterns

AFib: Consistent irregularities in the heart’s upper chambers distinguish AFib. You may want to make use of monitoring devices to detect these erratic patterns.

Palpitations: A regular pattern during palpitations, without sustained irregularities, aligns more with stress-induced or benign causes.
