Insights

Electrocardiogram (ECG) findings like incomplete right bundle branch block (RBBB), defective T wave (DTW), and crochetage R wave can aid in the early detection of atrial septal defect (ASD). These ECG markers show higher prevalence in ASD patients, aiding diagnosis.

Area of Science:

  • Cardiology
  • Medical Diagnostics

Background:

  • Atrial septal defect (ASD) is a common adult congenital heart defect.
  • Late diagnosis of ASD can lead to heart failure, arrhythmias, and embolism.

Purpose of the Study:

  • To evaluate the diagnostic significance of specific electrocardiographic (ECG) findings in atrial septal defect (ASD).

Main Methods:

  • Compared ECGs of 61 ASD patients with 66 healthy controls.
  • Assessed for right bundle branch block (RBBB), incomplete RBBB, defective T wave (DTW), and crochetage R wave.
  • Echocardiography confirmed ASD type and diameter.

Main Results:

  • Incomplete RBBB, DTW, and crochetage R wave were significantly more frequent in ASD patients (56%, 48%, 57% vs. 5%, 3%, 8%).
  • Specificities for these findings were high (95%, 97%, 92%).
  • Crochetage R wave showed a trend towards correlation with ASD diameter.

Conclusions:

  • ECG findings of RBBB, DTW, and crochetage R wave can assist in the early diagnosis of ASD.
  • These superficial ECG markers offer valuable diagnostic clues.

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...

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...

Dysrhythmias V: Evaluating Dysrhythmias

Dysrhythmias, also known as arrhythmias, are disturbances in the heart's rhythm that range from benign to life-threatening. A thorough evaluation is crucial for appropriate management and involves a comprehensive medical history, physical examination, and various diagnostic tests.Medical HistorySymptoms: Collect detailed information on palpitations, dizziness, syncope, chest pain, and fatigue. Note their onset, frequency, and triggers.Previous Cardiac Issues: Document any history of heart...

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...

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...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...
