25

Paper of how many mm/sec is used for rhythm and morphology as it has a larger number of complexes?

50

Paper of how many mm/sec is used for measurements as it has fewer complexes? Each large box is 0.1 seconds.

Sinus

What type of arrhythmia is phasic and associated with respiration, and increases with inspiration and decreases with expiration? It involves slower rates and vagal tone involvement.

Atrial

A P wave that increases in amplitude or duration is likely due to enlargement to either of which heart chamber type?

Amplitude

An increase in which component of an R wave is due to left ventricle enlargement?

Duration

An increase in which component of an R wave is due to left bundle branch block?

Amplitude

An increase in which component of an S wave is due to right ventricle enlargement?

Duration

An increase in which component of an S wave is due to a right bundle branch block?

Low

Will low or high amplitude on an ECG occur due to pleural effusion, pericardial effusion, obesity, hypothyroidism, pneumothorax, diffuse myocardial disease, and normal variations?
