An ECG Rhythm strip shows a ventricular rate of 46 BPM, a regular rhythm, a PR interval of 0.14 second, a QRS duration of 0.06 second, and one upright P wave before each QRS. This rhythm is___.

• Sinus rhythm

• Sinus bradycardia

• Sinus arrest

• Sinoatrial block

An ECG rhythm strip shows a ventricular rate of 128 BPM, a regular rhythm, a PR interval of 0.16 seconds, a QRS duration of 0.08 seconds, and one upright P wave before each QRS. This rhythm is sinus___.

• Irregular atrial and ventricular rhythm

• PR interval exceeding 0.20 seconds

The rate of sinus bradycardia is ___BPM.

• Slower than 60

• 60 - 100

• 80 - 120
