Examples of electrocardiogram in the following topics:

  • Nerve Conduction and Electrocardiograms

    • An electrocardiogram (ECG) is a record of the voltages created by the wave of depolarization (and subsequent repolarization) in the heart.
    • Explain purpose of the electrocardiogram and identify functions performed by electric currents in the nerve system

  • Electrocardiogram and Correlation of ECG Waves with Systole

    • An electrocardiogram, or ECG, is a recording of the heart's electrical activity as a graph over a period of time.
    • An electrocardiogram (ECG or EKG) is a recording of the heart's electrical activity as a graph over a period of time, as detected by electrodes attached to the outer surface of the skin and recorded by a device external to the body.

  • Statistical Literacy

    • The levels of troponin in subjects with and without signs of right ventricular strain in the electrocardiogram were compared in the experiment described here: http://www.bmj.com/content/326/7384/312.

  • Four Ways to Represent a Function

    • Examples include seismograph readings, electrocardiograms, and oscilloscope readings.

  • Electric Activity in the Heart

    • In the atria the electrical signal moves from cell to cell (see section on nerve conduction and the electrocardiogram) while in the ventricles the signal is carried by specialized tissue called the Purkinje fibers which then transmit the electric charge to the myocardium. shows the isolated heart conduction system.
    • Atrial and ventricular discharge through the Purkinje trees is assigned on a standard Electrocardiogram as the P Wave and QRS complex, respectively.

  • Syncope

    • Physical examination, and electrocardiogram are part of the initial evaluation of syncope and other more specific tools such as loop recorders may be necessary in clinically uncertain cases.

  • Heart Failure

    • An electrocardiogram (ECG/EKG) may be used to identify arrhythmias, ischemic heart disease, right and left ventricular hypertrophy, and presence of conduction delay or abnormalities (e.g. left bundle branch block).

  • The Cardiac Cycle

    • This information can be observed as an electrocardiogram (ECG): a recording of the electrical impulses of the cardiac muscle.
