Part B Practice Interpreting — Electrocardiograms Answer Key

What is the interpretation of this ECG tracing?

ECG tracing shows a heart rate of 60 bpm, with a regular rhythm and a prolonged PR interval (0.30 seconds). The QRS complex is 0.10 seconds.

Ventricular bigeminy

First-degree AV block is characterized by a prolonged PR interval (>0.20 seconds), with a normal QRS complex duration. part b practice interpreting electrocardiograms answer key

ECG tracing shows a heart rate of 40 bpm, with a regular rhythm and a widened QRS complex (0.20 seconds). There are no discernible P waves.

ECG tracing shows an irregularly irregular rhythm with a heart rate of 80 bpm. There are no discernible P waves, and the QRS complexes are of varying widths.

Ventricular escape rhythm is characterized by a slow heart rate, regular rhythm, and widened QRS complex. What is the interpretation of this ECG tracing

First-degree atrioventricular (AV) block
