1. What Are Heart Palpitations?

Heart Palpitations are sensations where you become unusually aware of your heartbeat. They are considered a symptom, not a medical diagnosis.

People often describe palpitations as:

Racing heartbeat
Pounding or thumping
Fluttering
Skipped beats

These sensations are usually felt in the chest but can also occur in the neck or throat. They may last for a few seconds, minutes, or even longer.

2. What Causes Heart Palpitations?

There are many possible causes, ranging from harmless triggers to underlying medical conditions.

2.1. Common Triggers

Stress and anxiety
Exercise
Excessive caffeine
Electrolyte imbalances (sodium, potassium, magnesium)

2.2. Medications and Substances

Certain medications can cause palpitations, including:

Decongestants
Asthma medications
ADHD treatments

Stimulants and drugs like cocaine or methamphetamine can also trigger symptoms.

2.3. Heart Rhythm Disorders

Some palpitations are linked to abnormal heart rhythms, known as Arrhythmia.

Examples include:

Atrial Fibrillation
Ventricular tachycardia

These are real medical conditions that require proper diagnosis and treatment.

Thyroid disorders
Anemia
Hormonal changes

In some cases, no clear cause is found—even after testing.
