The Impact of COVID-19 on Cardiac Arrhythmias

The COVID-19 pandemic has had far-reaching impacts on health, with one of the more concerning effects being the increased incidence of cardiac arrhythmias among recovered patients. Cardiac arrhythmias, which involve irregular heartbeats, can range from benign to life-threatening. Dr. Vanita Arora, an expert in cardiac electrophysiology, has highlighted the importance of understanding these risks and managing them effectively to ensure long-term heart health.

The Link Between COVID-19 and Cardiac Arrhythmias

COVID-19 is primarily known as a respiratory illness, but its effects extend far beyond the lungs. The virus has been shown to cause inflammation in various organs, including the heart. This inflammation, known as myocarditis, can lead to scarring of heart tissue, which in turn can disrupt the electrical signals that regulate the heartbeat, resulting in arrhythmias.

Patients who have recovered from COVID-19, especially those who experienced severe symptoms or required hospitalization, are at a higher risk of developing arrhythmias. These can manifest as palpitations, dizziness, or even sudden cardiac events. The stress that COVID-19 places on the heart, combined with the possible effects of medications used during treatment, further complicates the risk.

Recognizing the Symptoms

It’s crucial to be aware of the symptoms of cardiac arrhythmias, especially in the post-COVID period. Symptoms can include:

• Palpitations: A sensation that the heart is racing or fluttering.
• Dizziness or Fainting: Sudden feelings of light-headedness or blacking out.
• Shortness of Breath: Difficulty in breathing, even when resting.
• Thumping in the Chest / Chest Pain: Any discomfort or pain in the chest area.

These symptoms should not be ignored, as they may indicate a serious underlying condition that requires immediate medical attention.

Managing Post-COVID Cardiac Arrhythmias

If you’ve recovered from COVID-19 and are experiencing any symptoms of arrhythmia, it’s essential to consult a cardiologist. Dr. Vanita Arora stresses the importance of regular heart check-ups and monitoring. Diagnostic tools like electrocardiograms (ECG) and Holter monitors can help detect arrhythmias early, allowing for timely intervention.

Treatment for post-COVID arrhythmias varies depending on the severity. It may include medications to control the heart rate, anti-arrhythmic drugs, or in some cases, procedures like catheter ablation. Lifestyle modifications, such as reducing stress, following a heart-healthy diet, and engaging in moderate physical activity, can also play a significant role in managing the condition.
