Insights

Cardiac brucellosis is rare but serious. Analyzing electrocardiograms (ECGs) in brucellosis patients revealed abnormalities in 28.7%, highlighting the need for early cardiac damage detection to reduce mortality.

Area of Science:

  • Infectious Diseases
  • Cardiology
  • Internal Medicine

Background:

  • Brucellosis is a zoonotic infection with potential systemic complications.
  • Cardiac involvement in brucellosis is not well-characterized.
  • Electrocardiography (ECG) can reveal cardiac abnormalities.

Purpose of the Study:

  • To investigate the prevalence and types of cardiac manifestations in brucellosis patients.
  • To analyze electrocardiogram (ECG) findings in a cohort of brucellosis-infected individuals.

Main Methods:

  • Retrospective analysis of 108 brucellosis patients' electrocardiograms.
  • Categorization and summary of all observed ECG abnormalities.

Main Results:

  • 71.3% of patients had normal ECGs; 28.7% showed abnormalities.
  • Common ECG findings included nodal tachycardia, sinus bradycardia, and abnormal ST-T waves.
  • Less frequent findings included bundle branch blocks and arrhythmias.

Conclusions:

  • Cardiac manifestations of brucellosis are uncommon but associated with high mortality.
  • Abnormal ECGs in brucellosis warrant further cardiac evaluation, such as echocardiography.
  • Early ECG detection can indicate cardiac damage and guide timely intervention.

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...

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...

Electrocardiogram Fundamentals

Introduction
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
Parts of an ECG
An ECG utilizes electrodes on the skin...

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...

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...
