Common Ecg Ekg Rhythms Nurse Ekg Interpretation Cardiac Nursing

Interpreting ekg rhythm strips practice strip 1.

Common ekg rhythms. Arrhythmia or dysrhythmia are disturbances in the normal cardiac rhythm of the heart which occurs as a result of alterations within the conduction of electrical impulses. Pr interval measure from beginning of p to beginning of qrs 0 16 5. This area covers the most common questions asked about each rhythm.

Feel free to leave a comment or question as you review the content. Most ekg strips are 6 seconds the graph paper has a marking on the top or bottom to indicate every 3 seconds. Basic ecg rhythm interpretation objectives at the completion of this course the learner will be able to.

You will also find a question and answer section below each rhythm video. An ekg uses electrodes attached to the skin to detect electric current moving through the heart. Identify the sequence of normal electrical activation of the heart.

These impulses stimulate and coordinate atrial and ventricular myocardial contractions that provide cardiac output. P waves p wave for every qrs. Hr of boxes between r s 19 spaces 79bpm 2.

You can also count the large boxes 30 large boxes equal 6 seconds most 12 lead ekgs are 10 seconds long. Given a rhythm strip identify sinus atrial junctional and ventricular dysrhythmias and atrioventricular. Rhythm regular or irregular regular r r s are equal 3.

Examples of each ecg tracing are provided and after each article is a short video that simulates the acls ecg on a defibrillator monitor. Qrs measure from start of q to end of s 0 08.
