The generation of pacemaking stimuli
SA node located
Upper posterior wall of the right atrium
Each depolarization wave emitted by the SA node spreads through both atria producing a ...
The simultaneous contraction of the atria forces the blood they contain to pass through the ...
Atria-Ventricular valves between the atria and the ventricles
The only conducting path between the atria and the ventricles is the...
Depolarization conducts slowly through the AV node, since it is carried by slow moving ...
His Bundle and both bundle branches are bundles of rapidly conducting ...
Prukinje fibers use fast moving ions for the conduction. These are?
Depolarization of the entire ventricular myocardium produces a ...
The first downward wave of the QRS complex is the ...
Q wave, is often absent on EKG
The downward Q wave is followed by an upward
Any downward wave preceded by an upward wave is an
Rapid phase of ventricular repolarization is represented by the
Begins with the QRS and persists until the end of the T wave
Ventricular systole (contraction)
As a simple rule of thumb, the QT interval is considered normal when it is less than of the R to R interval at normal rates.
Precise QT interval measurements corrected for rate are called
