 Normal Sinus Rhythm Rate: 60-100 beats/min Rhythm: Regular P Waves: Present, ↑, one before every QRS PR Interval: ≤ .20 QRS: .08-.12 Sinus Brady All normal criteria except a rate < 60 Rate: < 60 Rhythm: Regular P Waves: Present, ↑, one before every QRS PR Interval: ≤ .20 QRS: .08-.12 Sinus Tachycardia All normal criteria except a rate > 100 Rate: > 100 Rhythm: Regular P Waves: Present, ↑, one before every QRS PR Interval: ≤ .20 QRS: .08-.12 Sinus arrhythmia Rate: 60-100 beats/min Rhythm: Irregular P Waves: Present, ↑, one before every QRS PR Interval: ≤ .20 QRS: .08-.12 Sinus Block Rate: 60-100 beats/min Rhythm: Irregular due to pause. When you measure the R-R interval it will fit exactly in the pause P Waves: Present, ↑, one before every QRS PR Interval: ≤ .20 QRS: .08-.12 Sinus Arrest Rate: 60-100 beats/min Rhythm: Irregular due to the pause. When you measure the R-R Interval, it will not fit in the pause P Waves: Present, ↑, one before every QRS PR Interval: ≤ .20 QRS: .08-.12 Premature Atrial complex (PAC) The complex will come early and will have an upright P wave (usually a little skinner and taller than normal). Will have an irregular rhythm due to early beat. The underlying rhythm is usually sinus Atrial Tachycardia Rate will be > 150 with a visible P wave (There will be two humps between each complex) Supraventricular Tachycardia (SVT) Rate: > 150 Rhythm: Always Regular P wave: No visible P waves (One hump between each QRS complex) Wandering Atrial Pacemaker (WAP) Will have three different shaped P waves in 6-sec strip, will have a regular rhythm. It is rare. Due to different places in the atria trying to pace the heart. Multifocal Atrial Tachycardia (MAT) A WAP with a rate > 100 Never use electricity to treat only drugs Atrial Flutter Sawtooth or picket fence baseline Cannot tell P’s from T’s Atria is firing faster than the ventricle Can be regular or irregular If rate is > 100 uncontrolled ventricular response If rate is < 100 controlled ventricular response Atrial Fibrillation Most common dysrhythmia Will have at least two out of three criteria -chaotic baseline -irregular rhythm-ALWAYS -no identifiable P wave If rate is > 100 uncontrolled ventricular response If rate is < 100 controlled ventricular response Wolf Parkinson White Syndrome (WPW Syndrome) Will have a delta symbol in QRS Significance: Pt. is predisposed to lethal dysrhythmia’s because of vulnerability Junctional Rhythms (Rate: 40-60 beats/min) -The rhythm is ALWAYS regular -Will be no P wave or an inverted P wave Premature Junctional Complex (PJC) Early beat with no P wave or an inverted P wave Accelerated Junctional Rhythm Rate > than 60 with no P wave or and inverted P wave Junctional Tachycardia Rate > 100 with no P wave or inverted P wave Junctional Escape Beat A Junctional beat that comes late. Beat will have no p wave or inverted P wave that will come late Premature Ventricular Complex (PVC) Early complex with wide, bizarre QRS -unifocal: 2 PVCs that look alike -multifocal: 2 or more PVCs that don’t look alike -couplet: 2 PVCs in a row -bigeminy: every other beat is a PVC -trigeminy: every third beat is a PVC Idioventricular Rhythm (IVR) Rate:20-40 Normally regular rhythm Will have all ventricular beats (wide, bizarre QRS): Accelerated IVR (AVIR) Rate > 40 with all ventricular beats Ventricular tachycardia Wide, fast, regular Ventricular rhythm with rate > 100 Lethal rhythm Ventricular tachycardia Can be monomorphic V-Tach (Same shaped QRS) or polymorphic tach ( different shaped QRS) With monomorphic v-tach-check to see of they have a pulse or not if yes with pulse give O2, IV acess If no pulse defib If unstable with pulse Cardioversion Torsades de Pointe polymorphic v-tach Short Run of V tach 3 or more PVCs in a row Ventricular fibrillation (v-fib) Rate, rhythm, P wave’s, QRS, cannot be identified. Just looks like line is quivering (fibrillation) Asystole Total absence of ventricular activity There will be very little quivering of the baseline No pulse, No rate, No rhythm, No activity Action CPR, IV access, transcutaneous pacing, medication therapy Pulseless Electrical Activity (PEA) Rhythm will appear to be normal, but the patient will have no pulse Nothing is wrong with the electrical system of the heart, but the mechanical system is not working Action CPR The most common cause is hypovolemia 1st degree Heart Block All is normal except the PR interval is Greater than .20 Will have the same number of P’s as QRS’s 2nd degree Mobitz I (Wenkebach) Will have more P’s than QRS’s The PR interval will longer until the QRS gets dropped (the cycle will repeat) 2nd degree Mobitz II Will have more P’s than QRS The PR interval will be the same for each complex 3rd degree Complete Block Will have mores P’s than QRS PR interval will vary (no pattern) TREAT WITH PACEMAKER + Atropine
