• Arrhythmia: An abnormal heart rate or rhythm. • Artifact: A substance, structure, or event that does not naturally occur in a situation. Examples include interference or electrical “garbage” on an ECG, crystals, lint, or contamination of a staining technique. • Bipolar: Having two poles or electrical charges. • Caliper: A pocket-sized tool used for measuring the height and width of the ECG waves and intervals. • Dextrocardia: The condition in which the heart is located on the right side of the chest, and the apex is pointing to the right. • Echocardiography: The use of ultrasonic waves directed through the heart to study its structure and motion. The visual record produced is called an echocardiogram. • Electrocardiogram: A record or recording of electrical impulses of the heart as produced by an electrocardiograph. • Electrodes: Adhesive patches that conduct electricity from the body to the ECG machine wires. • Ion: An electrically charged atom or the smallest component of an element. • Unipolar: Having one pole or electrical charge.
