Fast-glycolytic twitch fibers are useful for endurance events.

A dangerous toxin often used during warfare that is an acetylcholinesterase inhibitor is called __________________________________.

Using a stethoscope, you listen to the patient’s heart and you hear the expected “lub dub”. The “dub” sound indicates the closure of the __________________________________.

To recover normal rhythm, the surgeon decides to apply a few drops of __________________________, a substance usually released during sympathetic stimulation of the heart. 

During the Q wave, the conduction of the heart is moving through

The heart has no outside control, it is only controlled by the pacemaker cells of the heart.

These cells have _________________________________ that permit them to have an electrical syncytium, allowing for nearly simultaneous stimulation between them.

Thinking back to your physiology class, the cell type above has a unique structure that interlocks these cells together called the [cardiac1]. These junctions have adherence proteins called [cardiac2].

List all waves, intervals and segments of an ECG wave. Include the normal time range for each interval and segment.

A positive test in the patient’s blood would indicate the death of ____________________________ (cell type).
