Insights

P-wave dispersion (PWD) was prolonged in COVID-19 patients, correlating with inflammation markers. This electrocardiographic measure may help predict atrial fibrillation risk in these patients.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Biomarkers

Background:

  • COVID-19 is associated with cardiovascular complications, including atrial fibrillation.
  • P-wave dispersion (PWD) is an electrocardiographic parameter reflecting atrial electrical activity.
  • Inflammation plays a role in the pathophysiology of COVID-19 and its complications.

Purpose of the Study:

  • To evaluate P-wave dispersion (PWD) as a predictor of atrial fibrillation in patients with newly diagnosed COVID-19.
  • To investigate the relationship between PWD and inflammation markers (CRP, NLR) in COVID-19 patients.

Main Methods:

  • 140 COVID-19 patients and 140 healthy controls were included.
  • Electrocardiographic PWD was calculated to assess atrial fibrillation risk.
  • Inflammation markers including C-reactive protein (CRP) and neutrophil-to-lymphocyte ratio (NLR) were measured.

Main Results:

  • COVID-19 patients exhibited significantly higher PWD, white blood cell count, NLR, and CRP levels compared to controls.
  • PWD showed a significant positive correlation with CRP (rs=0.510) and NLR (rs=0.302) in COVID-19 patients.
  • A total of 9.3% of COVID-19 patients developed new-onset atrial fibrillation during follow-up.

Conclusions:

  • PWD is prolonged in patients with newly diagnosed COVID-19 compared to healthy individuals.
  • Elevated PWD correlates with increased inflammation markers (CRP, NLR) in COVID-19.
  • Pretreatment PWD evaluation may aid in predicting atrial fibrillation risk in COVID-19 patients.

Electrocardiogram01:29

Electrocardiogram

An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.
Three major waveforms are present in a typical ECG recording: the P wave, the QRS complex, and...

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Assessment of apical radial pulse

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Correlation between ECG and Cardiac Cycle01:25

Correlation between ECG and Cardiac Cycle

The electrical signals recorded on an electrocardiogram (ECG) occur before the mechanical processes of contraction and relaxation during the cardiac cycle.
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
