To identify the cardiac rhythm
What is the method for calculating heart rate in regular rhythms?
Dividing 300 by the number of large squares between two successive R waves
What is the normal duration of the QRS complex in a normal sinus rhythm?
Less than 0.12 seconds
What is the characteristic of P waves in a normal sinus rhythm?
Present and normal, upward, and rounded
What is the interpretation of an ECG with a heart rate between 60-100 bpm and a regular rhythm?
Normal sinus rhythm
What is the next step after calculating the heart rate in ECG interpretation?
Assess the P waves
Test your understanding of ECG rhythm and its components, including atrial depolarization, ventricular depolarization, and repolarization. Identify the principles of ECG and what each area indicates. This quiz is perfect for nursing students and professionals looking to review their knowledge of ECG and arrhythmia.
