|
Sympathetic Nervous System
|
Releases Norepinephrine
Increases conduction Increases heart rate Increases force of contration |
|
|
Parasympathetic Nervous System
|
Releases Acetycholine
Decreases aonduction Decreases heart rate Decreases force of contration |
|
|
Normal Sinus Rhythm
(NSR) |
Impulse originates from the SA node, normal P wave, normal QRS complex
Rate 60-100 BPM |
|
|
Sinus Arrhythmia
|
Impulse originates from the SA node, normal P wave, normal QRS. SA node forms impulses irregularly
|
|
|
Sinus Bradycardia
|
Impulse originates from the SA node, normal P wave, normal QRS complex. Rate slower than 60 BPM
|
|
|
Sinus Tachycardia
|
Impulse originates from the SA node, normal QRS, rate faster than 100 BPM
|
|
|
Supraventricular Tachycardia
|
Impulse originates somewhere above the ventricle. P waves are not seen or are buried in the previous complex; normal QRS complex. Faster rate than 100 BPM
|
|
|
Premature Atrial Contration
(PAC) |
Premature beat is preceded by an etopic P wave; normal QRS
|
|
|
Atrial Flutter
|
Impulse originates from multiple atrial foci; normal QRS, ventricular rhythm is irregular. The baseline is wavy and irregular or sometimes flat and straight
|
|
|
Atrial Flutter
|
Impulse originates from the ectopic atrial foci; normal QRS. Atrial rate is 250-350 BPM. The baseline resembles a swatooth or flutter pattern
