|
Sinus tachycardia |
Rapid regular rhythm originating in SA node
100-150 bpm |
|
|
Sinus bradycardia |
Slow rhythm originating in SA node
<60 bpm |
|
|
Supra-ventricular tachycardia |
Sudden onset of rapid heartbeat originating in atria
150-250 bpm |
|
|
Atrial fibrillation |
Electrical activity in atria disorganized (quivering)
May produce thrombi (clot) causing emboli in lungs or brain (stroke) |
|
|
Atrio-ventricular block |
Block in AV junction slows or impairs signals from SA node to ventricle |
|
|
Atrio-ventricular block |
Block in AV junction slows or impairs signals from SA node to ventricle |
|
|
Degrees of AV Block |
1st- asymptotic
2nd- vertigo, weakness, irregular pulse
3rd- hypotension, angina, bradycardia (~30) |
|
|
Premature ventricular contractions |
Abnormal heartbeats from right or left ventricular |
|
|
Ventricular tachycardia |
When 3 or more premature ventricular contractions (PVC) occur
>100 bpm |
|
|
Ventricular fibrillation |
Ventricular musculature of heart quivers
Most effective method to regulate fibrillation is defibrillation |
