One P wave before every QRS. No variation in P wave morphology.
What is Normal Sinus Rhythm?
The primary pacemaker of the heart.
What is the Sinoatrial node?
*Mode
*Heart Rate
*Atrial Output and Ventricular Output (mA)
*Capture Threshold
*Sensitivity
The P wave is prolonged.
What is 1st degree Heart Block?
*Fast and irregular
*Originating from multiple foci in ventricular myocardium
*Erratic waveforms
*Always non-pulsatile
*"Bag of worms"
What is Ventricular Fibrillation?
Twisting of the points, polymorphic ventricular tachycardia.
What is Torsades de Pointes?
The bunny ears on the EKG.
What is a bundle branch block?
The "I" stands for this in pacemaker modes.
What is "Inhibited"?
The fetus has a low heart rate and Mom has Lupus.
What is a congenital heart block?
*Drugs: Lidocaine, Amiodarone
*Cardioversion
*Wide QRS, no discernible P or T waves
*Fast and Irregular
*Brief or sustained
*Pulsatile or non-pulsatile
What is Ventricular Tachycardia?
Progressively increasing PR interval followed by a blocked conduction (QRS complex).
What is 2nd Degree Heart Block: Mobitz I (Wenckebach)?
The electrical connection from the top of the ventricles to the electrical system throughout the ventricle musculature.
What is the Bundle of His?
Pacemaker spikes with no conduction after the spike.
What is "Loss of Capture"?
The cardiac output drops by 15% with the loss of the atrial kick from this arrhythmia.
What is junctional rhythm?
2J/KG
What is the dose for defibrillation?
*Saw tooth flutter p waves
*variable conduction based on refractory period
*atrial rate 200-300 bpm
*normal qrs complex with normal rate
What is Atrial Flutter?
The conduction system throughout the musculature of the ventricles.
What is the Purkinje Fibers?
Pacemaker spikes at random places throughout the EKG.
What is under-sensing?
*Vagal maneuvers
*Adenosine
*Cardioversion
What is the treatment for SVT?
Ventricular issue in Tetralogy of Fallot.
What is Right Ventricular Hypertrophy?
*Automatic regular rhythm with narrow QRS complexes
*More p waves than QRS complexes
*Variable R-R intervals (variable conduction)
*Abnormal P wave morphology
*Atrial depolarization
*Ventricular depolarization
*Ventricular repolarization
This is stored on the defibrillation cart in the top drawer and is used to turn off a pacemaker in an emergency or patient demise.
What is a magnet?
*Reduce exogenous catecholamines
*Cool to 35-36degrees C
*Paralyze with NMB
*Correct/prevent acidosis
*Atrial overdrive pacing
*Amiodarone
What are ways to manage JET (Junctional Ectopic Tachycardia?
The ventricle doesn't form in utero due to mitral atresia or stenosis and leads to this syndrome.
What is Hypoplastic Left Heart Syndrome?
