Analysis.
They are both sinus rhythms, which are normal rhythms that originate in the heart’s sinoatrial
node.
Breakdown of the rhythms.
Top rhythm.
This rhythm has a rate of about 75 beats per minute, which is within the normal range of 60 to
100 beats per minute. The P waves, QRS complex, and T waves are all upright, and the PR
interval and QT interval are within normal limits. This is a normal sinus rhythm.
Bottom rhythm.
This rhythm has a rate of about 85 beats per minute, which is also within the normal range. The
P waves, QRS complex, and T waves are all upright, and the PR interval and QT interval are
within normal limits. This is also a normal sinus rhythm.
Top rhythm.
•
Rate: 75 bpm (within normal range of 60-100 bpm)
•
P waves, QRS complex, T waves: Upright
•
PR interval and QT interval: Within normal limits
Bottom rhythm.
•
Rate: 85 bpm (within normal range of 60-100 bpm)
•
P waves, QRS complex, T waves: Upright
•
PR interval and QT interval: Within normal limits
Both rhythms appear to be regular in their morphology, suggesting no underlying
cardiac abnormalities in this instance.
