Score _____ for cardiac pauses greater than 3 seconds for ages 6 years through adult.

Each large block on ECG graph paper (made up of 5 small boxes) represents ____ in amplitude.

We learned in Experiment 08 that the molecular weight of the Heavy species is 7 times greater than the molecular weight of the Light species.  In the current experiment, at a given temperature with the same number of molecules, we found that their pressures were about the same.  How is it possible for the Light species to exert the same pressure as the Heavy species? 

Score _____ if there is an irregularly irregular ventricular rhythm associated with replacement of consistent P waves by rapid oscillations that vary in size, shape, and timing.

A pattern of AV block in which there are varying PR intervals. Usually, there is progressive prolongation of the PR interval until a P wave is not conducted.

Sustained sinus tachycardia lasts at least:

VT originates in the _____.

A digital polysomnography (PSG) recording viewed in a ___ second window corresponds to a traditional ink pen recording at a paper speed of ___ mm/sec.

An ECG wave will be ____ (deflected _____) if the electrical activity of the heart approaches the positive lead.

A premature ectopic impulse originating in the ventricles. Usually caused by increased automaticity and electrical irritability in the ventricular conduction system or muscle tissue.
