What is Tachycardia?
Tachycardia is a condition where the heart beats faster than normal while at rest. For adults, a heart rate of more than 100 beats per minute (bpm) is generally considered tachycardia.
Symptoms of Tachycardia
The symptoms of tachycardia can vary depending on how severe the condition is and how well the heart is functioning. Common symptoms include:
- Rapid heartbeat
- Shortness of breath
- Chest pain or discomfort
- Dizziness or lightheadedness
- Fatigue
- Heart palpitations
- Fainting (syncope)
Causes of Tachycardia
Tachycardia can be caused by a variety of factors, including:
- Heart-related conditions: High blood pressure (hypertension), coronary artery disease, heart valve disease, or heart failure.
- Other medical conditions: Hyperthyroidism, anemia, or lung disease can also cause tachycardia.
- Stimulants: Caffeine, nicotine, and drugs such as cocaine or amphetamines.
- Stress or anxiety: Emotional stress or panic attacks can trigger tachycardia.
- Electrolyte imbalance: Abnormal levels of electrolytes in the blood can affect the heart’s electrical impulses.
- Medications: Certain prescription medications can cause tachycardia as a side effect.
Treatment Options for Tachycardia
The treatment for tachycardia depends on the underlying cause and the severity of the condition. Common treatment options include:
- Medications: Antiarrhythmic drugs, beta-blockers, and calcium channel blockers can help control the heart rate.
- Medical procedures: Catheter ablation, a procedure to destroy small areas of heart tissue that cause abnormal heart rhythms.
- Implantable devices: Pacemakers or implantable cardioverter-defibrillators (ICDs) can help regulate the heart rhythm.
- Lifestyle changes: Reducing intake of caffeine and other stimulants, managing stress, and following a heart-healthy diet.
- Surgery: In severe cases, surgery may be necessary to correct the underlying problem causing tachycardia.
- Monitoring and follow-up: Regular check-ups with a healthcare provider to monitor the condition and adjust treatment as needed.
