Heart Palpitations: Causes and When to Seek Help - Cardiology

Skipped heartbeat


Hello, Doctor! I had an echocardiogram and blood tests done last August, and everything has been relatively good since then.
However, after having a meal yesterday, my heart suddenly started to skip beats and then my heart rate increased.
After resting, my heart rate stabilized somewhat, but I still experienced skipped beats.
What could be the reason for this? I feel like it keeps cycling; whenever I have skipped beats, I feel like my heart is about to start racing again.
Please help me understand.
Thank you!

Heart palpitations can be concerning, especially when they occur suddenly after eating or during periods of rest. Based on your description, it seems that you experienced a sensation of skipped beats followed by an increased heart rate, which can be distressing. Understanding the causes of palpitations and knowing when to seek medical help is crucial for your peace of mind and overall health.

Palpitations are often described as the feeling that your heart is pounding, fluttering, or beating irregularly. They can be triggered by a variety of factors, including:
1. Dietary Influences: Consuming large meals, especially those high in carbohydrates or sugar, can lead to palpitations. This is often due to the body’s increased demand for blood flow to aid digestion, which can temporarily affect heart rhythm.

2. Caffeine and Stimulants: High caffeine intake from coffee, energy drinks, or certain medications can lead to increased heart rate and palpitations. If you consume these regularly, consider reducing your intake.

3. Stress and Anxiety: Emotional stress or anxiety can significantly impact heart rhythm. The body's fight-or-flight response can lead to increased heart rate and sensations of palpitations.

4. Hormonal Changes: Fluctuations in hormones, such as those experienced during menstruation or pregnancy, can also lead to palpitations.

5. Physical Activity: Engaging in vigorous exercise can cause temporary changes in heart rhythm, especially if you are not accustomed to it.

6. Underlying Health Conditions: Conditions such as anemia, hyperthyroidism, or heart disease can also contribute to palpitations. Given that you mentioned having a hemoglobin level of 10.8, which indicates mild anemia, this could be a contributing factor. Anemia can lead to increased heart rate as the body tries to compensate for reduced oxygen-carrying capacity.

7. Medications: Certain medications, including those for asthma or high blood pressure, can cause palpitations as a side effect.

In your case, the fact that the palpitations occurred after eating and were followed by a feeling of skipped beats suggests that it could be related to dietary factors or possibly anxiety about the sensations you were experiencing. The good news is that many palpitations are benign and do not indicate a serious underlying condition, especially in younger individuals without a history of heart disease.

However, it is essential to monitor your symptoms closely. Here are some guidelines on when to seek medical attention:
- Persistent Symptoms: If your palpitations continue or worsen, or if they occur frequently, it is advisable to consult a healthcare professional.

- Associated Symptoms: Seek immediate medical help if you experience chest pain, shortness of breath, dizziness, or fainting along with palpitations, as these could indicate a more serious condition.

- Family History: If you have a family history of heart disease or arrhythmias, it is prudent to discuss your symptoms with a doctor.

In conclusion, while occasional palpitations can be normal, especially in response to lifestyle factors, it is essential to remain vigilant. Given your recent experiences and mild anemia, I recommend scheduling an appointment with a healthcare provider for a thorough evaluation. They may suggest further testing, such as an electrocardiogram (ECG) or a Holter monitor, to assess your heart's rhythm over time. Additionally, addressing lifestyle factors such as diet, stress management, and regular exercise can help reduce the frequency of palpitations.
