Rapid Heartbeat

A rapid heartbeat, also known as tachycardia, is a condition where the heart beats too quickly. A normal heart rate for adults ranges from 60 to 100 beats per minute (bpm), while a rapid heartbeat is typically defined as a heart rate that exceeds 100 bpm.

Causes

• Anxiety or stress
• Dehydration
• Fever
• Anemia
• Hyperthyroidism (an overactive thyroid gland)
• Caffeine or nicotine consumption
• Certain medications, such as decongestants and asthma inhalers
• Heart conditions, such as atrial fibrillation or ventricular tachycardia
• Electrolyte imbalances, such as low potassium or magnesium levels

Symptoms

• A feeling of palpitations or fluttering in the chest
• Shortness of breath
• Dizziness or lightheadedness
• Chest pain or discomfort
• Fatigue or weakness
• Lack of energy

Diagnosis

A rapid heartbeat can be diagnosed using various tests, including:

• Electrocardiogram (ECG or EKG): a non-invasive test that measures the heart's electrical activity
• Holter monitor: a portable device that records the heart's activity over a 24-hour period
• Echocardiogram: an ultrasound test that evaluates the heart's structure and function
• Stress test: a test that monitors the heart's activity during physical exercise
• Blood tests: to check for underlying conditions, such as anemia or hyperthyroidism

Treatment

Treatment for a rapid heartbeat depends on the underlying cause. In some cases, no treatment may be necessary, while in other cases, medication or lifestyle changes may be recommended.

• Medications: such as beta blockers, calcium channel blockers, or anti-arrhythmic medications
• Lifestyle changes: such as reducing stress, avoiding caffeine and nicotine, and staying hydrated
• Catheter ablation: a minimally invasive procedure that uses heat or cold to destroy abnormal electrical pathways in the heart
• Pacemaker or implantable cardioverter-defibrillator (ICD): devices that help regulate the heart's rhythm
