Normal Sinus Rhythm
Impulse starts in the SA Node• Rate: Atrial & Ventricular 60-100 [normal limits]• Rhythm: Atrial and Ventricular are regular• P waves: Normal; each followed by QRS• PRI: 0.12 - 0.20 [normal limits]• QRS: 0.04 - 0.10 [normal limits]
Sinus Bradycardia
Impulse also starts in SA Node• These rhythms follow all the criteria for Normal sinus rhythm except for the rate.• Rate: Atrial and Ventricular < 60
Sinus Tachycardia
Impulse also starts in SA Node• These rhythms follow all the criteria for NSR except for the rate.Rate: Atrial and Ventricular 100-150
Premature Atrial ComplexUnderlying rhythm must first be identified!Ex. SR with a PAC
early P wave noted, which may appear slightly different than other P waves but PRI within normal limits.QRS within normal limits
Nonconducted PAC
Premature Atrial Complex in which their is a P wave but no QRS, this is called?
Atrial Flutter
The impulse originates in the Atria• The Atrial rate is 250-350 and rhythm regular• The PRI is not measurable (N/A) - Characteristic saw- tooth wave (called F waves) for atrial activity• The Ventricular rhythm may be regular or irregular• QRS within normal limits• If the Ventricular rate is 100 it is uncontrolled ____ ____.
Atrial Fibrillation
unable to measure [N/A] atrial rate• No discernable P waves - PRI & Atrial rhythm cannot be measured [N/A]• The Ventricular rhythm is irregular• QRS within normal limits• If the Ventricular rate is > 100 the rhythm is uncontrolled _____; if the Ventricular rate is < 100 the rhythm is controlled ______
Supraventricular Tachycardia
Regular Ventricular rhythm & rate > 150- 2. QRS: 0.04 - 0.10 [normal limits]• P waves may be seen but are often lost in the T waves: Atrialrate, rhythm, PRI is non-measurable [N/A]
Escape Junctional Rhythm
Ventricular Rhythm: Regular• Ventricular Rate: 40-60 bpm• QRS is usually within normal limits• Possible presentations of P waves- 1. P wave inverted and PRI is less than 0.12- 2. Upright P waves with PRI less than 0.12- 3. P wave is absent- 4. P wave is retrograde or coming behind the QRS
Accelerated Junctional
Same criteria as Junctional Rhythm, except the Ventricular rate is 60-100.
