Changing axis deviation and intermittent right bundle branch block during acute myocardial infarction
International Journal of Cardiology
|February 10, 2009
Summary
This study highlights a rare case of changing axis deviation with intermittent right bundle branch block during acute myocardial infarction. These electrocardiographic findings during myocardial infarction require careful attention.
Area of Science:
- Cardiology
- Electrocardiography
Background:
- Right bundle branch block (RBBB) has varied electrocardiographic (ECG) patterns.
- Prognosis of RBBB depends on underlying cardiac conditions, being good in isolation but poor with coronary artery disease.
- Changing bundle branch block and conduction disturbances are documented in medical literature.
Observation:
- Changing axis deviation, sometimes with atrial fibrillation, has been reported with acute myocardial infarction.
- Intermittent right axis deviation is rarely seen with left bundle branch block, atrial fibrillation, and acute myocardial infarction.
- Transient right axis deviation with left posterior hemiblock is an exceptionally rare finding, often linked to acute myocardial infarction.
Findings:
- This case presents changing axis deviation with intermittent right bundle branch block in a patient with acute myocardial infarction.
- The study emphasizes the occurrence and significance of these specific ECG changes during acute myocardial infarction.
Implications:
- Recognizing changing axis deviation and intermittent RBBB during acute myocardial infarction is crucial for accurate diagnosis and management.
- This case underscores the complexity of ECG manifestations in acute myocardial infarction and the importance of vigilant monitoring.
- Further research may elucidate the precise mechanisms and prognostic value of these dynamic ECG changes in ischemic heart disease.

01:19Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations
The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...
01:30Acute Coronary Syndrome I: Introduction
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...
01:18Dysrhythmias 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...
01:29Disturbances 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...

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...
01:25ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias
Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...
