Sudden Heart Palpitations

What is it?

Sudden heart palpitations are sensations of a rapid or irregular heartbeat that can occur unexpectedly and may be accompanied by other symptoms. This condition can be temporary or indicative of more serious heart issues.

Possible Causes

• Physical activity. Intense exercise can temporarily increase the heart rate.
• Stress or anxiety. Emotional states can trigger a faster heartbeat.
• Caffeine and stimulants. Excessive consumption of coffee, energy drinks, or certain medications can affect the heart rate.
• Heart arrhythmias. Irregular heart rhythms, such as atrial fibrillation, may cause sudden palpitations.
• Endocrine disorders. Conditions like hyperthyroidism can lead to an increased heart rate.

Symptoms

• Sensation of "fluttering" or "pounding" in the chest.
• Dizziness or weakness.
• Shortness of breath.
• Chest pain (in some cases).
• Sweating.

Diagnosis and Treatment

• Consulting a doctor. Immediate medical attention is required if palpitations are accompanied by chest pain, shortness of breath, or fainting.
• Diagnostic tests. Electrocardiogram (ECG), Holter monitoring, or blood tests can help determine the cause.
• Treatment of the underlying condition. This may include medication, lifestyle changes, or procedures like cardioversion.
• Avoiding triggers. Reducing stress and avoiding caffeine and stimulants can help prevent episodes.
