The Effects of COVID-19 Disease on Heart Rhythm

The COVID-19 disease caused by the novel coronavirus (SARS-CoV-2) created a public health crisis that has strained communities and healthcare systems around the world. Although, evolving research enables physicians to treat the complications of COVID-19 disease more effectively in emergency departments and intensive care units (ICU) worldwide. However, individuals with certain preexisting conditions continue to be disproportionately affected by the complications of this viral infection.


Latest Studies on Covid-19 in Relation to Heart Rhythm Disorders

Recent research has shown that infection with the novel coronavirus increases the risk for cardiac arrest and heart rhythm disorders (arrhythmias), including atrial fibrillation (Afib). Although COVID-19 appears to cause damage to heart cells, the viral infection may not represent the full picture. Therefore, researchers at the University of Pennsylvania discovered arrhythmias were more likely to develop in people with preexisting chronic diseases.

Furthermore, compared to healthy individuals, people infected with the novel coronavirus, who also live with cardiovascular disease have;

  • An increased risk of heart damage
  • Higher admission rates into ICU
  • Higher rates of death

Experts developing guidelines for the care of patients with arrhythmias and COVID-19 currently believe that atrial fibrillation alone is unlikely to increase the risk of getting infected with the novel coronavirus. However, afib usually comes with other underlying heart diseases, which weakens the heart and lungs causing inflammation in the body. Thus, people with chronic cardiovascular conditions are more likely to become severely ill and die if they develop COVID-19 disease. Moreover, weakened immune systems leave patients with heart disease and other chronic conditions particularly vulnerable to severe illness when infected with SARS-CoV-2. People with chronic diseases must limit social interaction and take precautions to reduce their risk of developing COVID-19.

If you have risk factors for atrial fibrillation or experienced irregular heartbeat symptoms, consult your physician or a cardiac electrophysiologist. Managing your heart rhythm disorder is a key component of caring for your health and avoiding severe complications. Dr. Alireza Nazeri and his team design individualized treatment plans for patients with Afib and other arrhythmias.

Early Detection of Atrial Fibrillation Can Save Lives!

Atrial fibrillation (Afib) is a strong risk factor for life-threatening diseases but thankfully, early detection of Atrial Fibrillation can save lives. However, in some cases, the arrhythmia remains undiagnosed until the patient is admitted to the hospital to manage an acute event such as a stroke.

People with Afib are five times higher at risk of a stroke compared with individuals without Afib.

This condition occurs when a blood clot blocks an artery that carries oxygenated blood to the brain, causes permanent damage to brain cells. Furthermore, many patients who had a stroke experience lifelong disability. Timely detection and diagnosis of Afib, followed by appropriate management such as treatment with blood thinners, could prevent a stroke, heart failure, and other disabling health conditions in patients with this type of arrhythmia.

A consultation with a cardiac electrophysiologist can benefits individuals with known risk factors for Afib including;

  • Obesity
  • High blood pressure (hypertension)
  • Family history of Afib
  • Sleep apnea
  • Diabetes
  • Thyroid disease
  • Heart failure
  • Previous heart attack


⚠️ In conclusion, the early detection of Atrial Fibrillation is vital ⚠️



So, If you have symptoms that suggest Afib, have been diagnosed with Afib, or have risk factors for developing Afib, you can schedule an appointment with Dr. Alireza Nazeri, a clinical cardiologist and cardiac electrophysiologist specializing in the diagnosis and treatment of heart rhythm disorders (arrhythmias). Standard office and virtual consultations are available. Visit Dr. Nazeri’s website at or call (713) 909-3166.

Ways to Detect Atrial Fibrillation at Home

Atrial fibrillation (AFib) is an abnormal heart rhythm that can occur suddenly and without warning. Characterized by skipping heartbeats and a racing heart rate, AFib can occur in people with heart conditions – but it can also occur in those without any known heart problems.

Having resources to monitor your heart rhythm at home is a great way to identify problematic heart rhythms. At-home monitors can be very helpful for the early detection of Atrial fibrillation (AFib) while connecting people to medical professionals faster. While they are not a replacement for professional medical care, these monitors can be a helpful diagnostic tool.

Dr. Nazeri discusses some of the available options for monitoring heart rhythms in the home setting:
