    Insights

    High mortality from advanced atrioventricular block with acute myocardial infarction can be reduced. Electrically pacing these patients with an endocardial catheter significantly lowers the expected mortality rate.

    Area of Science:

    • Cardiology
    • Electrophysiology

    Background:

    • Advanced atrioventricular block in acute myocardial infarction carries a high mortality rate.
    • Effective management strategies are crucial for improving patient outcomes.

    Observation:

    • Five patients with second- and third-degree heart block due to acute myocardial infarction were treated with endocardial pacing.
    • A silastic bipolar electrode catheter was utilized for pacing in these cases.

    Findings:

    • Pacing resulted in a considerable reduction in the expected mortality rate.
    • Four out of five patients spontaneously reverted to normal sinus rhythm within 10 days.
    • The average duration of pacing was 6.7 days.

    Implications:

    • Early introduction of endocardial pacing catheters is recommended for patients with atrioventricular block and acute myocardial infarction.
    • Continuous or demand pacing may significantly decrease mortality in this high-risk group.
    • This approach offers a potentially life-saving intervention for critical cardiac events.

    Electrophysiology of Normal Cardiac Rhythm01:19

    Electrophysiology of Normal Cardiac Rhythm

    The normal cardiac rhythm is a synchronized electrical activity that facilitates the regular and coordinated contraction of the heart muscle. This process is essential for efficient blood circulation throughout the body. The fundamental elements involved in establishing and maintaining this rhythm include the unique electrical properties of cardiac muscle cells, the sinoatrial (SA) node's pacemaker function, the specialized conducting system, and the ionic mechanisms underlying each phase of...

    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...
    Cardiac Action Potential01:30

    Cardiac Action Potential

    Cardiac action potentials are essential for proper heart function, enabling the rhythmic contractions needed for adequate blood circulation. Nodal cells and Purkinje fibers, specialized for electrical conduction, generate these action potentials.
    The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.

    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...

    ECG 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...
