Insights

COVID-19 can cause advanced atrioventricular block (AVB), a serious heart condition. This case study highlights a persistent AVB in a COVID-19 patient, emphasizing the need for monitoring and potential intervention.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Internal Medicine

Background:

  • The COVID-19 pandemic necessitates understanding its diverse clinical manifestations, especially cardiovascular complications.
  • Advanced atrioventricular block (AVB) is an uncommon but serious cardiac complication of COVID-19, with limited reported incidence.
  • The pathophysiology linking COVID-19 infection to AVB remains incompletely understood.

Purpose of the Study:

  • To report a case of advanced atrioventricular block (AVB) in a patient with COVID-19.
  • To highlight the persistence of AVB following COVID-19 recovery.
  • To discuss potential pathophysiological mechanisms and management strategies for COVID-19-associated AVB.

Main Methods:

  • Case report of a 48-year-old male with COVID-19 infection.
  • Clinical presentation, diagnostic confirmation (PCR, pulmonary involvement), and electrocardiographic findings of complete AVB.
  • Follow-up assessment of cardiac conduction post-recovery.

Main Results:

  • The patient presented with symptoms for 5 days prior to diagnosis of complete AVB.
  • COVID-19 diagnosis was confirmed with PCR and evidence of pulmonary involvement.
  • The atrioventricular block persisted for over one month after the patient's recovery from COVID-19.

Conclusions:

  • COVID-19 infection can lead to advanced atrioventricular block (AVB).
  • Potential contributing factors include inflammatory response, immune dysregulation, myocarditis, and medications.
  • While conservative management may suffice, pacemaker implantation is a consideration for persistent conduction defects.

Pulse rhythm

Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac muscle...
Disturbances in Heart Rhythm01:29

Disturbances in Heart Rhythm

Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Dysrhythmias IV: Characteristics of Bradyarrhythmias

Bradyarrhythmias are cardiac rhythm disorders characterized by a slower-than-normal heart rate, typically defined as fewer than 60 beats per minute. Some of which are discussed here:Sinus BradycardiaSinus bradycardia presents a heart rate lower than 60 beats per minute, with a regular rhythm originating from the SA node. The ECG typically shows normal P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and a normal QRS duration (0.06 to 0.10 seconds).First-Degree AV...

Cardiomyopathy II: Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
