Sinus Bradycardia
Sinus Bradycardia
Normal EKG tracing but there is a heart rate of less than 60/min
Sinus Tachycardia
Sinus
... [Show More] Tachycardia
Normal EKG tracing but the heart rate is greater than 100/min
Sinus Dysrhythmia
Sinus Dysrhythmia
Slight irregularity in the rhythm and is most likely associated with normal breathing patterns
Sinus Arrest
Sinus Arrest
A break in the normal EKG pattern. The SA node failed to fire and is not significant unless it lasts longer than 6 seconds
Atrial Flutter
Atrial Flutter
More severe than any sinus arrhythmias. It is a condition in which the atria are contracting much faster than the ventricles contracting
Atrial Fibrillation
Atrial Fibrillation
No organized contraction of the atria. They are in a quivering state, where blood clot formation due to stagnation of the blood in the ventricles is possible
Premature Junctional Complex
Premature Junctional Complex
An early impulse that occurs before the next expected beat. The P wave could occur before, after, or even buried within the QRS complex, causing irregularity in the rhythm
Junctional Escape Rhythm
Junctional Escape Rhythm
Reflects an impulse originating from the AV node, which is acting as the backup pacemaker. Atria and ventricles receive the impulse simultaneously, resulting in an absent P wave (P wave could be inverted). Heart rate will not exceed 60/min and the patient can exhibit signs of reduced cardiac output due to slower heart rate and lack of atrial kick
Accelerated Junctional Rhythm
Accelerated Junctional Rhythm
Same as escape rhythm but the rate is 60 to 100/min. Unlikely that the patient will exhibit signs of decreased cardiac output
Junctional Tachycardia
Junctional Tachycardia
Same as escape and accelerated but the heart rate is between 100 to 150/min. Faster the rate, the more likely the patient is to experience symptoms of palpitations or fluttering
Supraventricular Tachycardia/Narrow Complex Tachycardia
Supraventricular Tachycardia/Narrow Complex Tachycardia
Impulse comes from any area above the ventricles. The impulse is not following the normal electrical conduction pathway. Heart rate will be greater than 150/min. Due to the rapid nature of the heart rate, P waves are usually not visible
Premature Ventricular Complex
Premature Ventricular Complex
Ventricles contract out of normal sequence initiated by an ectopic focal point within the ventricles. P wave is not visible and the QRS complex is often wider than normal within an unusual shape. They are classified as occasional if there are 1-5 in 1 minute and frequent if there are 6 or more per minute
Ventricular Tachycardia
Ventricular Tachycardia
3 or more PVCs in a row with a ventricular rate greater than 100/min. Continuous state of contraction and relaxation of the ventricles, resulting in poor cardiac output. No noticeable P waves, QRS complexes are wide and unusual, and the T wave is deflected in the opposite direction
Ventricular Fibrillation
Ventricular Fibrillation
Emergency state in which the ventricles are not contracting, but quivering and there is no cardiac output. There are no discernible waves and the dysrhythmia is not compatible with life. Patient will most likely be unconscious due to extremely poor cardiac output and tissue oxygenation
