The cusps (flaps) of the bicuspid and tricuspid valves are anchored to the ventricle walls by fibrous “cords” called chordae tendineae, which attach to the wall by papillary muscles. This prevents the valves from being pushed up into the atria during ventricular systole.
Notice that five small squares on the paper form a larger square. The width of a single small square on ECG paper represents 0.04 seconds.
A common length of an ECG printout is 6 seconds; this is known as a "six second strip."
Each one of the figures represents an ECG pattern displaying three types of abnormal rhythms: Tachycardia, Bradycardia, and Arrhymthmia. Identify each.
