Palpitations: Causes, Diagnosis, and Treatment Options - Pulmonology

Palpitations, or the sensation of feeling your heart beating, can be a concerning symptom for many individuals, regardless of age. While it is true that palpitations are often associated with older adults, they can occur in younger individuals as well. The causes of palpitations can be varied and complex, ranging from benign to more serious conditions.


Causes of Palpitations
1. Physiological Causes: Stress, anxiety, and panic attacks can lead to palpitations. When the body is under stress, it releases adrenaline, which can increase heart rate and cause the sensation of palpitations.

2. Lifestyle Factors: Caffeine, nicotine, and alcohol can stimulate the heart and lead to palpitations. Additionally, certain medications, including decongestants and some herbal supplements, can also cause this symptom.

3. Medical Conditions: Palpitations can be associated with various medical conditions, including:
- Arrhythmias: Abnormal heart rhythms can cause the heart to beat irregularly, leading to palpitations.

- Hyperthyroidism: An overactive thyroid can increase metabolism and heart rate.

- Anemia: Low red blood cell counts can lead to increased heart rate as the body tries to compensate for reduced oxygen delivery.

- Electrolyte Imbalances: Imbalances in potassium, magnesium, and calcium can affect heart rhythm.

4. Structural Heart Issues: Conditions such as mitral valve prolapse or other structural heart diseases can also lead to palpitations.


Diagnosis
To diagnose the cause of palpitations, healthcare providers typically perform a thorough evaluation, which may include:
- Medical History: Discussing symptoms, lifestyle factors, and any underlying medical conditions.

- Physical Examination: Checking for signs of heart disease or other conditions.

- Electrocardiogram (ECG): This test records the electrical activity of the heart and can identify arrhythmias.

- Holter Monitor: A portable ECG device worn for 24-48 hours to capture heart rhythms over time.

- Echocardiogram: An ultrasound of the heart to assess its structure and function.

- Blood Tests: To check for thyroid function, electrolyte levels, and other potential causes.


Treatment Options
The treatment for palpitations depends on the underlying cause. If the palpitations are benign and not associated with any serious condition, lifestyle modifications may be recommended, such as:
- Reducing caffeine and alcohol intake.

- Managing stress through relaxation techniques or therapy.

- Regular exercise and a healthy diet.

If a specific medical condition is identified, treatment may involve:
- Medications: Such as beta-blockers for arrhythmias or medications to manage thyroid levels in hyperthyroidism.

- Lifestyle Changes: As mentioned, to reduce triggers.

- Procedures: In some cases, procedures like catheter ablation may be necessary to correct arrhythmias.


When to Seek Help
It is important to seek medical attention if palpitations are accompanied by other symptoms such as chest pain, shortness of breath, dizziness, or fainting. These could indicate a more serious condition that requires immediate evaluation.


Conclusion
In your case, it is understandable to feel confused about the diagnosis of palpitations, especially when tests like X-rays and ECGs have returned normal results. While it may seem that palpitations are more common in older adults, they can occur in younger individuals due to a variety of factors. If you are considering alternative treatments, such as seeing an osteopathic physician, it is crucial to discuss this with your primary healthcare provider to ensure a comprehensive approach to your health. They can help guide you on the best course of action based on your specific situation and symptoms.
