The P wave on the ECG. The P wave is the first positive deflection on the ECG. The P wave represents atrial depolarisation.

The PR Interval indicates AV conduction time. In this step you should measure the interval from where the P wave begins until the beginning of the QRS complex.

Normal Intervals     P-R interval = 0.12 - 0.20 sec (3 - 5 small squares)     QRS width = 0.08 - 0.12 sec (2 - 3 small squares)     Q-T interval 0.35 - 0.43 sec     * The PR interval should really be referred to as the PQ interval; however it is commonly referred as the PR interval

Sinus arrhythmia often accompanies sinus bradycardia, but the P waves have a normal morphology unless atrial disease is present. (See "Normal sinus rhythm and sinus arrhythmia"). A PR interval of up to 0.21 is normal in sinus bradycardia.

First Degree AV Block The normal PR interval (PRI) is 0.12 - 0.20 sec, or 120 -to- 200 ms. 1st degree AV block is defined by PR intervals greater than 200 ms. This may be caused by drugs, such as digoxin; excessive vagal tone; ischemia; or intrinsic disease in the AV junction or bundle branch system.

This ECG Interpretation course will show how to identify normal versus abnormal cardiac anatomy, cardiac cycle and electrical conduction through the heart.

bklynmed:  Ventricular Tachycardia (VT) often results in haemodynamic compromise due to minimal ventricular filling time and the absence of atrial kick. VT also has a tendency to transition into ventricular fibrillation. The causes of VT can include myocardial ischaemia, cardiac drug toxicity and electrolyte imbalance. Pulseless VT requires urgent defibrillation.  Regularity: Regular, but sometimes can be slightly irregular. Rate: 100-250bpm P waves: None, or not associated with the QRS…

This guide features an introduction to EKGs and how they work and also includes detailed sections covering the main types of arrhythmias, such as sinus rhythms, atrial rhythms, junctional rhythms, ventricular rhythms, and heart blocks. Helpful illustrations, along with the rate, rhythm, P wave, PR interval, and QRS complex, of each rhythm covered are also included to help with identification. http://www.examville.com/examville/Ekgs%20&%20Ecgs%20%20%20-PRID1900 #nursing #medicine #health…
