electrocardiogram

Examples of electrocardiogram in the following topics:

• 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.

• 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).
