    Insights

    Patients with ischemic heart disease frequently experience ventricular arrhythmias, including precursors to ventricular fibrillation. This study identifies electrophysiological criteria for diagnosing various heart rhythm disorders.

    Area of Science:

    • Cardiology
    • Electrophysiology
    • Cardiac Arrhythmias

    Context:

    • Ischemic heart disease (IHD) is a major cause of morbidity and mortality.
    • Arrhythmias are common complications of IHD.
    • Advanced diagnostic tools are crucial for understanding cardiac electrical activity.

    Purpose:

    • To investigate the prevalence of ventricular arrhythmias in patients with ischemic heart disease.
    • To establish electrophysiological criteria for diagnosing various supraventricular and ventricular tachycardias.

    Summary:

    • Continuous electrocardiogram (ECG) monitoring, intracardiac electrography, and programmed electrical stimulation were used.
    • Ventricular extrasystoles, potential precursors to ventricular fibrillation, were found in 66% of chronic IHD patients and 95% of acute myocardial infarction patients.
    • Electrophysiological criteria for diagnosing sino-atrial, atrial, nodal atrio-ventricular, supraventricular, and ventricular paroxysmal tachycardias were determined.

    Impact:

    • Provides insights into the high incidence of ventricular arrhythmias in IHD.
    • Offers diagnostic electrophysiological markers for various tachyarrhythmias.
    • Aids in risk stratification and management of cardiac arrhythmias in ischemic heart disease patients.

    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...
    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 the T...

    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...
