29Q: What's the electrical conduction system of the heart?
A: It is essentially the [blank_start]wiring[blank_end] of the heart. These are cells that carry [blank_start]electricity[blank_end] through the heart and cause the heart to [blank_start]contract[blank_end] and [blank_start]relax[blank_end].
Cardiac Cells:
[blank_start]Pacemaker[blank_end] cells - primary function is to [blank_start]generate[blank_end] and conduct [blank_start]electrical[blank_end] [blank_start]impulse[blank_end] throughout the heart muscle
[blank_start]Myocardial[blank_end] cells - primary function is muscle [blank_start]contraction[blank_end] and [blank_start]relaxation[blank_end]- Awiring
- Belectricity
- Ccontract
- Drelax
- EPacemaker
- Fgenerate
- Gelectrical
- Himpulse

30[blank_start]Automaticity[blank_end] is the ability of a cell to "spontaneously" generate an electrical impulse.

31[blank_start]Depolarization[blank_end] - an electrical event expected to result in contraction
- ADepolarization
32The SA node:
- is located in the [blank_start]upper[blank_end] [blank_start]right[blank_end]-hand corner of the right [blank_start]atrium[blank_end]
- is known as the "[blank_start]normal[blank_end] [blank_start]pacemaker[blank_end]" of the heart; [blank_start]first[blank_end] [blank_start]intrinsic[blank_end] pacemaker
- initiates [blank_start]atrial[blank_end] depolarization --> produces the [blank_start]P[blank_end]-wave of an ECG
- normally possesses the [blank_start]highest[blank_end] level of automaticity; [blank_start]fastest[blank_end] intrinsic rate
- normally, cardiac electrical impulses begin in the [blank_start]SA[blank_end] [blank_start]node[blank_end]
- as the electrical impulse leaves the SA node, it's conducted through the [blank_start]atrium[blank_end], causing [blank_start]depolarization[blank_end], and contraction of the atrium
- impulse spreads across atria via [blank_start]intranodal[blank_end] and [blank_start]intra[blank_end]-[blank_start]atrial[blank_end] pathways

33The AV node:
- located in the [blank_start]lower[blank_end] [blank_start]left[blank_end]-hand corner of the right [blank_start]atrium[blank_end]
- primary function is to [blank_start]delay[blank_end] the conduction of the electrical impulse from the [blank_start]SA[blank_end] node as it travels to the [blank_start]bundle[blank_end] of [blank_start]His[blank_end] and [blank_start]bundle[blank_end] branches
- allows time for the [blank_start]atrium[blank_end] to fully [blank_start]contract[blank_end] and [blank_start]empty[blank_end] the blood into the ventricles
- creates the [blank_start]PR[blank_end]-[blank_start]Interval[blank_end] on the ECG
- can be the [blank_start]back[blank_end] [blank_start]up[blank_end] pacemaker if SA node fails; [blank_start]second[blank_end] intrinsic pacemaker

41QRS Morphology
The QRS complex can have different [blank_start]shapes[blank_end] which depend on how the electrical impulse is conducted through the [blank_start]bundle[blank_end] [blank_start]branches[blank_end].
Sometimes if an [blank_start]artery[blank_end] is blocked off due to heart disease, heart attack, or other factors, the electrical impulse cannot be conducted via its normal route so it has to take a detour in order to [blank_start]depolarize[blank_end] the ventricle.
In some cases, the electrical impulse could take [blank_start]longer[blank_end] to travel through the ventricle causing the [blank_start]QRS[blank_end] to appear wider than [blank_start]normal[blank_end].
