Final answer:
The statement that junctional rhythm has a heart rate the same as sinus bradycardia is false.
Step-by-step explanation:
The statement that junctional rhythm has a heart rate the same as sinus bradycardia is false.
Sinus bradycardia refers to a condition where the heart rate is lower than normal (less than 60 beats per minute) due to a slower electrical signal initiation by the sinoatrial (SA) node, which is the natural pacemaker of the heart. On the other hand, junctional rhythm refers to a condition where the electrical signal originates from the atrioventricular (AV) node or the bundle of His, bypassing the SA node. This can result in a heart rate that is slower or faster than sinus bradycardia depending on the specific circumstances.
For example, in junctional rhythm, the heart rate can range from 40 to 60 beats per minute, while in sinus bradycardia, the heart rate is generally below 60 beats per minute.
