What is the primary purpose of rhythm analysis in cardiac monitoring?
✔✔ To identify and diagnose abnormal heart rhythms and related cardiac conditions.
How can you distinguish between atrial fibrillation and atrial flutter based on their
characteristics?
✔✔ Atrial fibrillation typically shows an irregular rhythm without distinct P waves, while atrial
flutter features a regular rhythm with distinct flutter waves.
What does a prolonged PR interval usually indicate?
✔✔ It suggests a first-degree atrioventricular (AV) block.
What does a broad waveform often signify in cardiac monitoring?
1
, ✔✔ It may indicate a ventricular arrhythmia or conduction block.
What is the normal duration range for the QT interval?
✔✔ It should be less than 440 milliseconds in men and less than 460 milliseconds in women.
How do you recognize a rapid, wide complex rhythm?
✔✔ It suggests a ventricular origin, such as a ventricular arrhythmia or bundle branch block.
What can ST-segment elevation indicate in a patient experiencing chest pain?
✔✔ It may suggest an acute myocardial infarction.
