EKG Chapter 6 Atrial Dysrhythmias Study Guide 2023 LATEST QUESTIONS AND ANSWERS ALREADY PASSED A+

1. Myocardial infarction, valvular problems, neurological influences: What medical conditions place pressure on the atria, causing atrial dysrhythmias to occur? 2. the waveform has an equally positive and negative deflection on the ECG tracing: In a premature atrial complex (PAC), the P wave may be biphasic. This means: 3. Premature Atrial Complexes (PAC): Which atrial dysrhythmia has a cardiac complex that occurs too soon, has a positively deflected P wave, and other than being early, has no other abnormal features? 4. Three: How many different P wave configurations in the same lead indicate a wandering atrial pacemaker (WAP)? 5. Organic heart disease and drug toxicity: WAP is a normal finding in children, older adults, and well-conditioned athletes. It may also be found in patients with . 6. Wandering Atrial Pacemaker (WAP): Identify the following rhy 7. 60 to 100 beats per minute: What is the rate of wandering atrial pacemaker rhythm (WAP)? 8. 101-150 beats per minute: What is the rate of multifocal atrial tachycardia (MAT) rhythm? 9. multifocal atrial tachycardia (MAT): Identify the following rhyt 10. 250-350 beats per minute: What is the rate of atrial flutter rhythm? 11. atrial flutter: Identify the following rhythm: 12. Atrial kick: What occurs immediately prior to ventricular systole when blood is ejected from the atria into the ventricles? 13. 10% to 30%: The loss of atrial kick contributes to what percent decrease in cardiac output? 14. atrial fibrillation: What atrial dysrhythmia has lower-case "f" waves, chaotic atrial electrical activity, and irregular R to R intervals? 15. atrial fibrillation: Identify the following rhythm:
